How to 3D Print Figures from Start to Painted Finish

Trying to 3D print your first figure but unsure whether to go with FDM or resin printing, or where things tend to go wrong? As a general rule, resin printing has the edge for small-scale figures where facial details and hair strands matter, while FDM works well for larger or chibi-style prints you want to produce without fuss. In my experience, resin tends to shine at the small end of the scale (roughly 7-10 cm), while deformed-style figures over 15 cm often look perfectly good printed on an FDM machine. These boundaries shift depending on the printer, settings, and finishing approach, so treat them as tendencies rather than hard rules.

With that in mind, this guide walks through the entire workflow: support placement and split-line planning, primer prep, drying pitfalls, resin safety essentials (ventilation, protective gear), and practical benchmarks like sanding from 400 to 1000 grit, spraying at roughly 30 cm distance, applying 2-3 thin coats, and curing for about a week.

Choosing a Printing Method for Figures

A 3D printer builds objects layer by layer from digital data, but for figure making, the method you choose shapes the outcome far more than the machine's raw capabilities. The two main options for home use are FDM (Fused Deposition Modeling, which melts and deposits plastic filament) and resin printing (which cures UV-sensitive resin with light). Both use a slicer (software that converts 3D data into layer-by-layer instructions), but their strengths for figure work diverge sharply.

FDM keeps material costs low and is relatively straightforward to operate, but surfaces tend to show visible 積層痕 and reproducing fine facial features, thin hair strands, or sharp accessory edges straight off the printer is tough. Resin printing, on the other hand, handles small parts and delicate sculpted detail far better, producing surfaces with a cohesive sense of depth even before paint. The trade-off is that you need to account for support removal marks, washing, and post-curing (exposing the washed print to UV light for final hardening).

In my workshop, 7-10 cm character figures almost always look better in resin. The skin surfaces connect more smoothly and the hair catches light in a natural way. At that scale, the resin print already feels like it is winning before any paint goes on. On the flip side, deformed-style figures over 15 cm have turned out just fine on FDM. When you build up the cheek and clothing surfaces a bit thicker and commit to proper priming, the slight roughness of FDM can actually add a sense of volume.

When FDM Is the Right Call

FDM really comes into its own for larger figures. Home machines commonly offer build volumes of 180 x 180 x 180 mm or 256 x 256 x 256 mm, and that pairs well with squat chibi proportions or display pieces where the base is part of the presence. Materials are mainly PLA and ABS filaments, and the workflow from printing to cleanup is relatively simple, making it the easier entry point if you have never used a 3D printer before.

The obvious weakness is 積層痕, but for figures, the real question is not whether lines appear but where they appear. On busy surfaces like flowing hair or fabric folds, roughness is more noticeable. On rounded chibi faces or broad cloak surfaces, sanding and primer go a long way toward cleaning up the impression. When I print larger mascot-style figures on FDM, I deliberately avoid chasing fine detail and instead design for a thicker primer coat. That approach makes it easier to balance the finished piece.

Another advantage is the low psychological cost of failure. Cleanup after a bad print is lighter than with resin, so it is easy to iterate on pose variations or rethink split lines. Since splitting directly affects both paintability and where seams show, starting with a rough FDM proof to verify the big shapes before committing to a final print is a very practical workflow.

When Resin Printing Is the Right Call

Resin printing excels at small, detail-rich figures. Facial contours, eyelash areas, hair strand edges, and ornamental steps, the kind of detail that "sells if you can see it," all come through cleanly. The difference is especially noticeable at the 7-10 cm scale. Even using the same 3D data, resin produces smoother skin surfaces and more natural-looking highlights on hair. The silhouette reads as tight even without paint, which makes it easier to gauge the sculpt's quality early on.

That quality, however, comes with post-processing strings attached. Resin prints must be washed to remove uncured resin immediately after printing, then post-cured under UV light. On top of that, poorly placed supports leave visible marks on prominent surfaces, making support strategy extremely important. In practice, slicers like CHITUBOX let you manually redistribute supports so the marks land in less visible spots, and for figures, this makes a huge difference. Concentrating supports on the front of the face or the outer edge of the hair leads to shapes that distort during sanding, so the standard approach is to route them to the back side and mating surfaces.

Resin printing is not simply "high detail, therefore beginner-friendly." A more accurate description is "high-detail output is achievable, but the method demands preparation that extends to your workspace." Handling resin requires ventilation and protective equipment as baseline requirements, and the process does not fit neatly on a single desk. You gain a better finish at the cost of more workflow management. Even so, if getting the face area right is your top priority, resin is the first method to consider.

Method Comparison Table

Text alone can make the decision feel harder than it is, so here is a table summarizing the differences for figure work. The goal is not to declare a winner but to show where the effort lands.

With the table in front of you, the beginner's decision becomes clearer. For small, high-detail work where faces, hair, and fine ornaments matter, resin is the primary choice. For chibi proportions or prints over 15 cm, FDM is perfectly capable. Add proper sanding and primer, and FDM pieces look impressive at normal viewing distances.

If you wanted to visualize this comparison, a five-axis radar chart (print quality, post-processing, safety, cost, difficulty) or a two-column table like the one above works well.

Method Selection Flowchart

Choosing a method is easiest when you weigh three factors: size, desired level of detail, and workspace conditions. For figure work, running through them in this order keeps things straightforward.

1. Decide whether you are making something small or large.
2. Decide how much fine detail you need in the face, hair, and accessories.
3. Check whether you can set up washing and ventilation space.

Following this sequence: if you want a 7-10 cm figure with strong facial detail, lean toward resin. If it is a deformed-style figure over 15 cm and you plan to shape the surface with primer and paint, FDM is a strong candidate. For in-between sizes, pick resin if hair texture and costume sculpting are priorities, or FDM if a round silhouette and lower cost matter more. Resin also assumes you have somewhere to wash and post-cure, so if that space is hard to arrange, FDM will keep the overall workflow moving more smoothly.

As a diagram, you could start with "Are you making something small and high-detail?" Branch to resin for "yes" and to "Is it a deformed-style figure over 15 cm?" for "no." Layer on "Do you have ventilation and a wash station?" and even a beginner can make a grounded decision. Personally, if someone wanted to maximize the thrill of a finished piece, I would point them toward resin for a small character. If the goal is to get a larger piece into physical form without overthinking, FDM is the better starting point.

Equipment, Materials, and Software

3D Printer and Materials

Before you start building, matching your desk setup to your chosen method prevents mid-project supply runs. The bare minimum for figure making is a 3D printer, material, and a 3D model to print. A 3D printer builds objects layer by layer from digital data. For home use, FDM and resin are the dominant methods.

If you go with FDM, grab PLA filament alongside the printer. It is the most approachable material. For figure work, it handles deformed proportions and larger sizes well. Home FDM machines with build volumes from the 180 x 180 x 180 mm range up to 256 x 256 x 256 mm give a useful reference point. Whether you can print the head in one piece or need to split off the arms and base depends on that build volume, and the choice matters more than you might expect. I find that leaving this vague causes problems not at the printing stage but during modeling. A 12 cm figure fits easily, but spread the pose wide or add a base, and you eat up space fast.

For resin printing, the essentials are the printer and UV-curable resin. This is the route when small faces, hair strands, and accessory details are the priority, but printing is only part of the equation. You also need to plan for washing. The resin itself is hard to forget, but in practice, you need wash alcohol, a work tray, and plenty of paper towels for the process to flow without interruption. In my setup, keeping extra trays and kitchen paper on hand for resin washing speeds up cleanup significantly. Running out of space for wet parts causes more mess than the resin itself.

At this stage, you are ready to start if you have:

• A 3D printer (FDM or resin)
• Material (PLA filament or resin)
• A 3D model to print
• A small test part for initial calibration

The 3D model can be your own creation or a downloaded file, but for figures, split-line placement directly impacts the finish. Thinking about not just paintability but also where seams will be visible saves a lot of rework later.

Slicers and Modeling Software

Even with a printer and materials ready, you cannot print without two types of software: modeling software to create the shape, and a slicer to convert it into printable layers. The workflow goes like this: sculpt in ZBrush or Blender, export as STL or 3MF, load into a slicer like CHITUBOX, PrusaSlicer, Ultimaker Cura, or OrcaSlicer, slice, and then print.

For figure sculpting, ZBrush is the industry standard, and Blender is a fully capable free alternative. Blender runs on Windows, macOS, and Linux and includes sculpting tools. When you want to work on overall proportions and part splitting in one environment, Blender is extremely convenient. One thing to watch is that high-density meshes sent straight to the slicer can cause slowdowns and glitches. Optimizing or decimating dense figure sculpts before slicing reduces those issues.

Slicer choice follows your printing method. For FDM, Ultimaker Cura, OrcaSlicer, and PrusaSlicer are popular. OrcaSlicer reads STL, 3MF, OBJ, STEP, and more, with deep tuning options. PrusaSlicer supports STL, OBJ, and AMF with fine-grained control including manual supports. For resin, CHITUBOX is the go-to. For figures, relying solely on auto-generated supports is risky; manually adjusting them makes it much easier to keep marks off visible surfaces. Simply avoiding the front of the face and the outer hair line in favor of the back side and joint surfaces noticeably improves the result.

Pre-work checklist:

• Modeling software (ZBrush or Blender)
• Export format (STL or 3MF)
• Slicer (Cura, OrcaSlicer, PrusaSlicer, CHITUBOX)
• Ability to generate and adjust supports
• 3D data that is already split or has splitting planned

Post-Processing and Painting Supplies

A freshly printed figure is closer to raw material than a finished product. Getting it to look good requires tools for support removal, sanding, washing, priming, and painting. Postponing this prep means even a clean print will not reach its potential.

The post-processing basics are nippers, sandpaper, a tack cloth, and cleaning supplies. Nippers handle support removal and gate trimming. FDM involves cutting thicker excess, while resin work means removing finer supports, so thin-blade nippers work well for both. Sanding follows the principle mentioned earlier: 400 to 1000 grit covers the range from rough shaping to surface refinement. A tack cloth for wiping away dust before priming is a small step that pays off. For resin, you also need alcohol to wash off uncured material.

Painting supplies center on primer/surfacer, paint, brushes, spray cans, and topcoat. Since 3D-printed surfaces are never perfectly uniform, the priming step is especially important. For brush painting, fine-tip and flat brushes work. For even coverage on large areas, an airbrush or spray can is the better tool. Entry-level airbrush kits typically come with a 0.3 mm nozzle, which handles base coats well. With spray cans, holding about 30 cm from the part and building up 2-3 thin coats rather than one heavy pass reduces the risk of runs and uneven coverage.

Organizing what you need by category makes it easier to track:

• Post-processing supplies

Nippers, hobby knife, sandpaper, tack cloth, alcohol, paper towels

• Priming supplies

Primer/surfacer, filler/putty as needed

• Painting supplies

Water-based acrylic paint, brushes, spray can or airbrush, topcoat

For beginners, I recommend building around water-based acrylics. The ease of cleanup is just as valuable as the color quality. Painting fine details by brush and covering large surfaces with primer and spray is a combination that works extremely well for figures.

Safety Gear and Workspace

For figure making, your workspace setup can matter more than the tools themselves. Resin printing in particular trades high detail for real workspace demands. The four safety essentials are gloves, goggles, a mask, and ventilation. These protect you not only during resin handling but also when sanding and spray-painting.

Even with FDM, ventilation deserves attention. For resin, roughly dividing your workspace into zones for printing, washing, drying/curing, and waiting-for-paint prevents chaos. I found that confining messy work to a tray rather than spreading it across the desk is dramatically easier. Washed parts, in particular, need a clear staging spot; if that is vague, your efficiency drops fast. You do not need a full workshop. Just separating the wet zone from the dry zone makes a big difference.

Safety prep checklist:

• Gloves
• Safety goggles
• Mask
• Ventilated workspace
• Tray for messy work
• Paper towels and waste bin
• Drying space for painted parts

Looking at the whole desk setup, comfort depends more on having the small accessories than on the printer itself. Connecting the software workflow (modeling screen to slicer screen) with your physical desk layout in your mind prevents bottlenecks like "the file is ready but there is nowhere to wash" or "there is nothing to wipe dust with before painting."

Preparing the 3D Model and Planning Splits

Getting Data and Checking Licenses

Figure 3D data comes from two sources: downloading from a sharing platform or making it yourself. Downloading gets you to a testable shape quickly; sculpting your own gives freedom over pose, clothing, and expression. I find that using a downloaded model for the first figure to learn the workflow, then moving to Blender or ZBrush for the second, is a natural progression.

For self-made models, Blender (free, with sculpting via Dyntopo and voxel remesh for roughing out shapes, good for checking fabric flow and hair volume) and ZBrush (the standard for figure-oriented sculpting, strong for refining organic surfaces) are the main options.

When using downloaded data, the easy thing to overlook is the license. Skipping this can be fine for personal display but creates problems with exhibitions, sales, or publishing modified files. Check commercial use, modification rights, and redistribution rights before anything else. For figures, even light adjustments like pose changes or adding split lines can count as modification, so reading the terms matters more when the data is designed for fabrication.

Scale, Wall Thickness, and Mesh Optimization

Before throwing your data into a slicer, sort out size and wall thickness to reduce failures. Figures are often sized by visual impression, but what actually drives printability and post-processing ease is how thin the wrists, ankles, hair tips, and accessory points get. Making things too thin for appearance's sake causes more breakage during support removal and sanding than during printing itself.

For hollow resin prints, plan wall thickness from the start. A common starting point is around 1.2 mm, but the ideal value varies with resin and printer. Planning drain holes for uncured resin inside hollow parts is essential. Rather than picking a fixed diameter, test iteratively: start at 1 mm, check how resin flows out during washing, then step up to 1.5 mm or 2 mm as needed (most cases settle somewhere in the 1-3 mm range). Always test-print with your actual machine and resin, and verify compatibility with your wash method (ultrasonic, agitation, or flushing). These numbers are starting points for experimentation, not final specifications.

Polygon count cleanup also matters. Sculpts pushed to high detail in ZBrush or Blender may look fine but cause slow slicer imports, strange artifacts, or long processing times. Decimation helps here, reducing polygon count while preserving outlines and key surfaces. Rather than importing every hair strand and fabric wrinkle at maximum mesh density, keeping detail only where it visually matters results in more stable data and more predictable prints.

Splitting Strategy and Hiding Seams

When splitting a figure, you are designing not just for printer fit but also for gluing ease and paintability. A common mistake is splitting along visible surfaces just because it is easier to print that way. Cutting across the side of the face, the center of the chest, or the front of the thigh puts seams right where the eye goes, and no amount of post-processing makes that comfortable.

The baseline rule: avoid splitting on visible surfaces. Then, aim to split along boundaries that make painting easier. For example, separating front and back hair sections makes brush access simple, and detaching arms from the torso opens up the underarms and clothing seams for brush or spray. Over-splitting for painting convenience, though, increases total seam area and can pull down overall quality. Paintability and seam concealment should always be weighed together.

Good places to hide seam lines include fabric folds, hair part lines, the back side of ornaments, and collar or sleeve edges. I once aligned a shoulder split with the collar edge, and the glue line disappeared into the shadow, barely visible in the finished piece. Routing the split through areas that already look like boundaries makes post-processing noticeably easier. It is more effective to blend the seam into the sculpt's existing information than to run a straight line across a smooth surface.

For parts designed to be glued, add alignment pins and sockets to stabilize assembly. Arms and hair strands where angle misalignment is immediately obvious benefit from interlocking shapes rather than flat mating surfaces. Too-shallow pins shift during gluing, and too-tight ones block the paint layer from fitting, so the design needs to account for the entire assembly sequence.

A diagram showing how split lines follow clothing edges and hair seams, and which surfaces remain visible after assembly, would clarify this concept. The difference between a line visible from the front and one that only shows at an angle is significant.

Modeling with Support Marks in Mind

During modeling, thinking ahead about where support marks will land makes post-processing much easier. Figures naturally draw your attention to the front, but the real planning happens in areas like underarms, the inside of the hair, under skirts, and base contact surfaces, places where some roughness is acceptable and easy to fix. Anticipating which surfaces will need supports gives you more freedom when orienting the model in the slicer.

For example, if you make the outer surface of the hair a large, smooth plane, any support marks that land there become painful to correct. Building a little texture into the back side or creating mating surfaces that will be hidden after assembly lets you process marks without affecting appearance. Ornamental detail on figures is not purely decorative; it also functions as real estate for hiding support contact points.

This thinking connects directly to split design. Making the inside of mating surfaces and hidden back faces slightly larger gives you space to work on support marks. Auto-generated supports tend to place contact points on prominent surfaces, so designing the model with manual adjustment in mind leads to more consistent results. Surfaces that absolutely must stay clean, like the face and the front of the legs, benefit from conscious protection at the modeling stage. The stress difference after printing is substantial.

Diagrams would help here too. Showing the split-line routing alongside support-mark hiding spots (underarms, inner hair surfaces, ornament backs, base undersides) makes it intuitive to see how much of the finishing should be designed into the model before printing.

Slicer Settings and Printing Tips

The Shared Workflow

Slicer settings involve many parameters, but for figure work, running through them in the same order every time produces more consistent results than starting from scratch. Whether you are using an FDM slicer like Cura, OrcaSlicer, or PrusaSlicer, or a resin slicer like CHITUBOX, the core logic is largely the same. The priority is: first ensure the print does not detach mid-build, then route support marks to inconspicuous locations.

A repeatable sequence:

1. Import the model
2. Set the orientation
3. Auto-generate supports as a starting framework
4. Manually relocate supports from prominent surfaces
5. Check the slice preview for island geometry and unsupported overhangs
6. Adjust build plate adhesion
7. Export the output file (G-code, ctb, etc.)

When setting orientation, rotate the model so that the face front, leg fronts, and chest, the showcase surfaces, avoid support contact points. The base underside, inner hair surfaces, costume linings, and faces hidden after assembly are all acceptable spots for some residual marks. This is where the "support mark escape zones" discussed earlier get put into practice.

Auto-generated supports are useful for an initial layout, but on figures they often place contact points on the cheeks or outer legs. I find it fastest to let the auto-generator reveal gaps, then manually move the conspicuous ones. It is quicker than placing everything by hand and cleaner than leaving everything on auto.

Build plate adhesion takes priority over detail tuning. If adhesion fails, no amount of careful support placement or orientation matters because the print detaches and you start over. Dial in adhesion first, then refine for appearance.

A visual comparison of bad support placement (contact points on the cheeks and base top surface) versus good placement (routed to inner hair and base underside) would make this immediately clear.

Resin Printing Settings (Introduction)

Resin printing delivers fine detail, but support contact placement translates directly to finish quality. The following section covers orientation decisions, manual support techniques, and base-tilting strategies that have proven effective in practice. Try mapping these to your own model as you read.

For hollow models, think about not just the outer shell but how resin drains from the interior. Without drain holes, uncured resin gets trapped inside, and shapes that are hard to wash out create ongoing problems. Place holes low and on inconspicuous surfaces, like the inside of a leg, the base underside, or a mating surface hidden after assembly. If the model has multiple connected chambers, provide more than one drain path. Rather than locking in a fixed hole size, prioritize confirming that the cavity shape and wash path actually allow resin to flow out.

For exposure time, layer height, and lift parameters, working from the printer and resin manufacturer's recommended profile is far more reliable than guessing. Resin printing tempts you to tweak everything, but starting from recommended values and adjusting only where necessary keeps failure rates low. Beginners in particular tend to misattribute exposure problems to support setup, so treating parameter calibration and placement adjustment as separate tasks helps maintain clarity.

In the slice preview, focus on thin elements likely to fail: hair tips floating in air, weapon protrusions, and sleeve ends. Resin printing reproduces surfaces beautifully, but missing the first support contact on these fragile features leads directly to chips and deformation.

FDM Settings

With FDM, support marks are less sharp than resin, but managing 積層痕 becomes the central finishing challenge. The core tension is that reorienting the model reduces supports but makes layer lines more visible, and vice versa. For figures, balancing this trade-off is the main game.

For example, tilting the face upward reduces front-face supports but introduces stair-stepping on the cheeks and forehead. Standing the model too upright increases supports on outstretched arms and legs. My approach is to mentally separate "surfaces where support marks are easy to fix" from "curved surfaces where 積層痕 are hard to sand." The back of the hair and the sides of the base tolerate some support residue, while the cheeks and outer thighs, with their broad curves, are painful to smooth out if layer lines run across them.

Layer height is a direct trade-off between appearance and print time. Thinner layers make curves smoother but extend print time. Thicker layers print faster but increase the sanding burden. For FDM figure work, evaluating total time (including sanding and priming) rather than just print time is the practical approach. Settle on a quality-versus-time target first, then dial in the layer height.

Before printing, systematically eliminating failure points beats adding more settings. A checklist for figure-specific concerns:

1. Are support contact points concentrated on visible front surfaces?
2. Does the orientation cause strong 積層痕 on the face or front of the legs?
3. Has auto-support generated unnecessary supports?
4. Do thin tips and overhang starts have adequate support?
5. Is build plate adhesion sufficient?
6. For hollow resin models, is the drain path clear?
7. Are drain holes positioned away from visible surfaces?
8. Does the slice preview show any island geometry or unsupported floating sections?
9. Is the output file format correct for your printer?
10. Is the division between "finished surfaces" and "acceptable roughness surfaces" still intact?

This checklist is less about verifying settings than about protecting the finished appearance. A figure is not half-done when it prints successfully; the impression is set by what you see after sanding and finishing. Thinking about supports in terms of "where will the finished piece look best?" rather than "can a support go here?" cuts through most of the decision paralysis.

A side-by-side comparison of good and bad support layouts on the same model, showing contact points on the cheeks and front thighs versus the inner hair and back surfaces, would make the value of manual adjustment obvious.

Post-Print Processing

Resin: Washing and Post-Curing

Even when a resin print looks clean off the build plate, skipping the pre-paint prep leaves tackiness and support marks intact. Figures concentrate viewer attention on small areas like the face and hands, so following the wash-and-cure sequence consistently makes a major difference in how primer sits later.

1. Start by removing supports. Use hobby nippers or flush cutters to clip at the base before prying away, which keeps the contact mark shallow. Early on I tended to just pull supports off, but that chips fingertips and hair ends easily and creates more repair work. Working slowly, reducing contact points before removal, gives cleaner results. A close-up photo of clipping at the support base would illustrate this well.
2. Wash off uncured resin with alcohol. Figures with lots of detail trap liquid in grooves and undercuts, so do not just swirl the surface; make sure the wash reaches recesses. If a slippery film remains, sandpaper clogs quickly in the next step. A shot of the wash container with parts arranged inside helps readers visualize the process.
3. Dry thoroughly after washing. Moving to the next step before the part is fully dry risks leaving liquid hidden in recesses, which shows up as uneven patches after post-curing. Hollow parts especially need attention to whether resin has drained completely through the drain paths.
4. Post-cure once dry. This step sets the surface hardness so the part is ready for sanding and priming. Uncured parts feel unstable under sandpaper and do not sand evenly. A photo comparing the surface texture before and after curing would be effective here.
5. Sand the support marks after curing. Focus on leveling only the raised areas to avoid flattening surrounding detail. Sandpaper in the 400-1000 grit range covers the progression from rough removal to surface refinement. On broad surfaces like cheeks and skin areas, use a flat backing or sanding sponge rather than finger pressure alone to prevent waviness.
6. Fill only the chipped or deeply marked areas with putty as needed. Apply just enough to fill the bottom of the defect rather than coating the whole area, and the re-sanding step stays short. A comparison of a cheek or hair back before and after thin putty application would be practical.
7. Remove sanding dust for a final check. Rather than brushing by hand, wipe with a tack cloth to pick up fine particles. This prevents the next primer coat from going on gritty.

FDM: Sanding and Filling

For FDM, the focus of surface prep shifts from washing to managing 積層痕. On figures, those step lines translate directly into visible shadow patterns after painting, so pre-paint surface work drives the final look. The material tends to feel harder than resin, so concentrating sanding effort on priority areas keeps things efficient.

1. Remove supports after printing. FDM supports sometimes come off in chunks, but around thin parts, do not twist them off. Clip segment by segment with nippers for safety. Weapon tips and hair strand ends are less likely to chip when you cut each contact point individually rather than pulling a whole section. A before-and-after support removal comparison photo would help gauge the workload.
2. Sand the 積層痕. Start by knocking down only the prominent ridges, then blend the overall surface. Sandpaper from 400 to 1000 grit works well: level the rough steps, then transition to a paint-ready surface. On curved areas like cheeks and outer thighs, avoid pressing hard with fingertips alone. A sanding block or sponge sander preserves the shape better. A photo showing the switch between flat and curved sanding techniques would be helpful.
3. Fill deep step lines with putty. Trying to sand away every layer line is time-consuming. Filling the deepest valleys first and then smoothing produces a more stable result. For broad surfaces like base sides and backs, this approach reaches an even finish faster. In my experience with larger FDM figures, selectively filling visible ridges before sanding gives a more uniform surface than sanding alone.
4. Sand again after the putty cures to blend the transitions. Any remaining edges will show up as lines after priming, so run your finger across the surface and keep going until the step is undetectable.
5. Remove dust with a tack cloth. FDM dust clings with static and settles into grooves and corners. Blowing with air alone is not enough; a final wipe improves primer adhesion. A photo of tack-cloth wiping is unglamorous but adds credibility to the process description.

FDM finishing is driven more by post-processing than by the print itself. Rather than trying to eliminate every trace of 積層痕, prioritizing the surfaces the viewer sees from the front gives the best return on time invested. Treating the back of the hair, the base underside, and other low-visibility areas differently from the face and front legs creates a natural density gradient in the finish.

Shared Safety and Tool Notes

Whether you are working with resin or FDM, pre-paint post-processing revolves around cutting, sanding, and wiping. The quality of these steps depends as much on tool choice and cleanup discipline as on technique. These are not flashy steps, but sloppiness here shows up the moment primer goes on.

1. Use hobby nippers or flush cutters for trimming, and be careful of sharp support stubs. Thin supports tend to fly off when clipped, so brace your hand on the desk while cutting. Thin-blade and single-edge nippers are well-suited to detailed work; brands like GodHand and Tamiya are popular in the modeling community. A photo of the basic tool lineup (nippers, sandpaper, tack cloth) helps set expectations.
2. Wear a mask when sanding to avoid inhaling dust. Dust left on the desk transfers to the next part, so wipe down the area after each session. Putty dust in particular spreads fine particles widely; keeping it off finished surfaces matters.
3. Dispose of wash waste and contaminated materials properly rather than rinsing them down the drain. For resin, cleanup is part of the process. A tidy workspace keeps the next session's precision high.
4. Use a tack cloth before priming to settle the surface. Even if it looks clean to the touch, dust hides in recesses. Clearing it out reduces grit and foreign-particle inclusions in the primer coat.

For post-processing tools, investing in variety of roles rather than expensive upgrades is more practical. Having a distinct tool for cutting, sanding, filling, and wiping reduces hesitation during work. Some of the reasons paint does not sit right trace back not to the paint itself but to an inadequately prepped surface. Eliminating irregularities you can feel before moving to the stages that change appearance is the shortest path to a higher-quality finished piece.

Pre-Paint Surface Preparation

The Role of Primer/Surfacer

Pre-paint surface preparation is the single most important step in determining a figure's finish quality. The sequence is: sand to remove major roughness, clean off dust and debris, apply primer/surfacer, sand again to refine the surface, then move to paint. Rather than thinking of this as a linear task, treat it as a back-and-forth process of gradually improving the surface.

Primer is not just a gray undercoat. It reveals small scratches and sanding marks that are invisible on bare material, stabilizes paint adhesion, and normalizes surface appearance across different substrates. Sanded FDM surfaces, filled areas, and resin surfaces after support removal all have slightly different textures, but one coat of primer makes it immediately obvious where roughness remains. In my workflow, the first primer coat frequently reveals steps and dips that were invisible before. Skipping this step visibly changes the final gloss and surface smoothness.

For beginners, spray-type primers like Mr. Primer Surfacer or Tamiya Super Surfacer are easiest to handle. They lay down even coats on both large surfaces and small parts without building up too much thickness. Hold the can about 30 cm from the part, and rather than trying to cover in one pass, mist on thin layers until the surface is just tinted. Build up coverage over several light passes. Too close and primer pools in corners; too far and it dries grainy.

The Sand-Prime-Sand Loop

What separates good surface prep from average is not stopping after one pass. In practice, you sand, clean, prime, let it dry, and sand again, repeating until the surface is dialed in. Surfaces that catch light and reveal imperfections, cheeks, thighs, shoulders, and base sides, benefit the most from this loop.

For grit progression, starting around 400, then stepping through 600, 800, and 1000 works well. Use 400 to shape areas with deep steps or putty marks, 600 to refine the scratches, and 800-1000 to reach a paint-ready finish. Vary pressure and grit by area: rougher where it is still uneven, finer where the surface is close to final. This protects detail from being worn away.

The critical discipline in this loop is not stopping when the first primer coat looks smooth. Even when the surface appears even, angling a light across it often reveals dips and waviness that a straight-on view misses. I check with my fingertip as well, and touch is more honest than sight. Any spot where your finger catches will almost certainly show through the final paint.

For glossy or semi-gloss finishes, this loop directly determines the outcome. Matte finishes hide some roughness, but any sheen amplifies surface imperfections through reflection. Residual dips under the topcoat are what make a piece look "somehow cheap" even when the color is right. Before-and-after primer photos, or a shot of checking for dips with angled light, would convey why this step matters so much.

Surface Differences Between FDM and Resin

Surface prep looks similar across methods but targets different problems. FDM produces 積層痕 as continuous lines across the surface; the roughness reads as parallel ridges. Broad curves show this most, so starting with a coarser grit to knock down ridges and using primer to check valley depth fits the FDM workflow. For showcase areas like the face and front of the legs, start at 400 grit and step up through 600, 800, and 1000 as needed.

Resin, on the other hand, produces relatively smooth surfaces overall but leaves scattered point defects: support contact marks, small bumps, and faint wash-related unevenness. The work is less about chasing continuous ridges and more about eliminating localized blemishes. Finer grits from the start protect the detail better. For delicate features like hair strands, eyelash areas, and fingertips, starting at 600 or higher and working cautiously is safer than aggressive passes with coarse paper.

Ignoring this difference and sanding both the same way leads to frustration: FDM ridges never seem to go away, and resin detail gets sanded off. A useful mental model is that FDM surface prep is about rebuilding the surface, while resin surface prep is about preserving a good surface and spot-removing defects. Both require primer, but for FDM it acts almost like a building material, while for resin it serves more as an inspection layer.

The same figure looks different depending on the method, and surface prep effort changes accordingly. Matching the sanding starting point to the material, checking status with primer, and cycling back to sanding is the most reliable approach. Once this is dialed in, the sense of a "finished product" appears before any paint is applied.

Painting Your Figure

Paint Types and Selection

The first decision that trips people up is which paint to build around. The most accessible starting point for beginners is water-based acrylic paint. The odor is mild, brush control is forgiving, and it works well when you want to test skin and fabric colors as you go. For a first kit, I find that anchoring on water-based acrylics is the path with the fewest surprises.

Lacquer-based paint dries fast, forms a durable film, and produces sharp-looking surfaces. It pairs well with primer and handles large areas cleanly. The trade-off is strong fumes and solvent management, so it is best suited to those with a prepared workspace. When spraying or airbrushing lacquer, ventilation, a mask, and gloves are the minimum, and a spray booth makes a real difference. Overspray travels further than expected, so covering nearby surfaces with newspaper or drop cloth in advance makes cleanup much easier.

Enamel paint is less a base-coat workhorse and more a specialist for panel lining and wipe-off shading. It excels at adding depth to grooves and recessed detail, and it delivers a sense of dimension quickly. Rather than painting an entire figure in enamel, use it after water-based or lacquer base coats to add finishing texture. That division of labor keeps things manageable.

The application method also shapes the result significantly. Brush painting has low startup cost and lets you use only the colors you need in small amounts. Fine-tip brushes excel at eyes, mouth lines, and ornament borders, and you can start with nothing more than a desk. Spray cans and airbrushes dominate when you need even coverage over large areas. A 0.3 mm nozzle is standard for entry-level airbrush kits and handles base coats smoothly. The initial investment and setup effort go up, but for large surfaces like skin, hair, and clothing, the reduction in brush marks directly improves the look.

In practice, the most natural division is: face, nails, and accessory edges by brush; hair, clothing, and skin surfaces by spray or airbrush. You can brush everything, but switching to spray for larger areas adds a level of uniformity that reads as professional. When airbrushing skin tones with water-based acrylics, two thin passes eliminate the powdery quality of the first coat and produce a softer, more settled finish, making it especially effective for skin.

The Basic Painting Flow

Painting works best when you build up layers in order rather than jumping around. The standard sequence:

1. Apply the undercoat
2. Lay down the base color
3. Add shadow and highlight tones
4. Brush in fine details
5. Apply decals if using
6. Seal with clear coat or topcoat

The undercoat goes over the primed surface and sets the color foundation. A lighter undercoat makes colors more vivid; a darker one adds weight. For beginners, aiming for a value close to the final image is enough. Applying too thickly at this stage disrupts the smooth surface you built up during prep, so think of this coat as "setting a direction" rather than covering completely.

The base color defines the figure's overall impression. The key here is not trying to finish in one coat. Whether brushing or spraying, 2-3 thin layers with drying time between them reduce runs and unevenness far more effectively than one thick pass. For brush work, thin the paint slightly and lay it down rather than scrubbing it across the surface. For spray, maintain a consistent distance and build up a thin mist over multiple passes.

Shadow and highlight tones create the illusion of three-dimensional light on the figure. Beginners do not need full airbrush gradients; darkening the roots of the hair and the depths of fabric folds, then lightening the cheeks, shoulders, and tops of the knees, already produces a visible shift. An airbrush blends these transitions softly, but dry-brushing with a regular brush to pick up highlights also works to add dimension.

Fine detail work is where brushes are strongest. Eyes, eyelashes, accessory borders, belt edges, buttons, shoe color breaks: these are about line accuracy more than surface coverage. A fine-tip brush tightens the color boundaries and makes the whole piece read as more finished. Spraying the base, then detailing with a brush, is a combination that gives consistent results even for beginners.

If using decals, wait until the underlying paint is fully dry. Handling decals over insufficiently cured paint damages the film and lifts edges. Rushing between detail work, decals, and sealing risks destroying the layered finish you have built up. The waiting time between steps is itself part of the finishing process.

Topcoat and Curing

The topcoat applied after painting protects the finish and unifies the appearance. Matte finishes calm the texture and give the figure a "completed product" look. Semi-gloss retains a slight lifelike quality on skin and hair. Gloss emphasizes shine on mechanical or ornamental parts. Whichever sheen you choose, a topcoat layer ties together the color and surface consistency.

Apply in thin coats here as well, avoiding heavy passes. Over decals, too much topcoat at once can lift edges or create a blurred impression. Start with a light misting pass to settle the surface, then build up. When processing multiple small parts, use clips or holders to keep them steady and cover the work area to prevent overspray problems beyond just whitening or dust contamination.

Even when the surface feels dry to the touch after painting, the interior of the film may not be fully cured. Waiting for each layer to dry before proceeding is standard, but after all steps are done, allowing at least a week of curing hardens the film enough to resist fingerprints and scuffs. I have rushed a piece into a case or adjusted its pose right after finishing and fogged the skin and hair surfaces as a result. Even for display pieces that will not be handled, the paint film is most vulnerable right after completion.

For supplementary visuals, a comparison of brush-applied versus spray-applied finishes, and a diagram showing how thin layers build up color, would make this section much clearer. Painting looks like the act of putting on color all at once, but in reality it is the act of stacking thin films in sequence. Once that mental shift clicks, beginners find it much easier to reach the look they are aiming for.

Common Problems and Solutions

Breaking Through the Surface Prep Wall

When 積層痕 will not go away, the problem is usually not enough steps in the process rather than not enough sanding. FDM tends to leave ridges across surfaces, and resin leaves small rough spots around support contacts. Trying to fix everything in one aggressive pass with coarse grit just trades one problem for another: deep scratches that are even harder to remove. In modeling work, sandpaper from 400 to 1000 grit covers the useful range: knock down ridges first, then refine the surface scratches.

I failed early on by underestimating primer coverage issues. I would see thin, patchy primer and think, "the next coat will fill it in." The result was layer line valleys peeking through the final paint as visible stripes. After switching to holding the spray about 30 cm away and building up in three thin passes, the surface became dramatically more uniform. Primer is not a tool that fixes surfaces by being applied thick. It works as a thin, even film that reveals where the flaws still are.

When layer lines persist, this troubleshooting sequence helps:

• Level the ridges with 400-grit sandpaper
• Apply putty sparingly, just enough to fill the grooves
• Sand again once dry to blend the transitions
• Mist primer to make remaining lines and scratches visible
• Re-fill only the areas where lines still show
• Final-pass with 800-1000 grit to smooth the surface

The important principle is not re-doing the entire surface every time. Targeting only the problem areas with small cycles of sanding, filling, and priming keeps edges sharp and protects detail on faces and fingertips. Thick putty applications look convenient but cause shrinkage and new step lines. For the purpose of filling layer-line valleys, thin "sealing the dip" application is more manageable than "building a new surface."

When support marks are conspicuous, sanding alone is an uphill battle. Not placing marks on visible surfaces in the first place is far more effective than removing them afterward. As discussed in earlier sections, route contact points to back surfaces, inner hair, skirt undersides, and other low-visibility areas. When marks do end up on prominent spots like cheeks or outer arms, do not sand broadly. Use a small, targeted file or sanding stick to level just the bump, then lay a thin coat of filling primer over the spot to rebuild the surface. On areas where you want to preserve a flat plane, localized treatment works better than rubbing the whole area.

Painting Troubleshooting Q&A

When paint will not stick or beads up on the surface, suspect incomplete cleaning before blaming the paint. Residual uncured resin, skin oils from handling, or release agent remnants can destabilize adhesion even over primer. Rather than layering more paint on top, wash with mild detergent, dry, wipe with alcohol if needed, and re-prime. Paint applied over a contaminated surface tends to wrinkle or develop inconsistent sheen after drying, making the problem more visible rather than less.

Brush marks usually trace back to paint consistency and application style rather than the brush itself. Thick paint dragged across a large area leaves tracks. Thin the base color slightly, and instead of trying to cover in one pass, let each coat dry before adding the next. Two to three coats with drying time between is the reliable range. Touching a half-dry film just drags it and makes the marks worse. For broad surfaces like hair, skin, and cloaks, brush painting has inherent limits. Switching to spray or airbrush for those areas and reserving the brush for edges and fine detail is the most natural solution.

Insufficient drying is another common stumbling block. Even when the surface feels dry, the interior may not be set. Holding the figure too soon leaves fingerprints, and applying topcoat over soft paint causes fogging. Use one week of curing time as a baseline, and the principle is simple: the more recently the paint was applied, the less you should touch it. I once reinserted a figure into its base while the paint was still soft and left a thumbprint. That was not a skill issue but a patience issue. Setting the piece in a box or case labeled "do not touch today" is enough to prevent most of these accidents.

For illustrations, a side-by-side of paint beading on a contaminated surface versus a clean re-primed surface, and brush marks on a broad area versus the same area after switching to spray, would communicate the decision points well. Failure shots feel embarrassing, but they are exactly the kind of material that shows when to change approach.

Revising Splits and Supports

Split-line problems hit hardest not right after printing but after painting begins. A seam that seemed fine at assembly becomes a visible line once primer and color go on. Splitting mid-surface on the side of the face, the middle of the chest, or the front of the thigh, surfaces without existing visual information, makes the seam almost impossible to disguise.

Ideally, split lines follow existing visual boundaries in the sculpt from the start. But if a split is already in the wrong place, it can still be salvaged. When a seam shows, rather than just filling it, convert it into a line that makes visual sense. If it can be moved to a garment boundary, score it as a panel line. If it cannot be fully erased, adding a thin strip detail, a stitch line, or a stepped molding gives the boundary a reason to exist, and the repair reads as design. I once tried to force a seam back to a perfectly smooth plane and ended up creating visible asymmetry. Adding detail to blend the seam actually produced a better-looking result.

Support mark concentration can also be improved by revisiting splits. If contact points cluster on the front, splitting the part so it can be reoriented to push marks to the back or shadow side reduces the total processing burden. Slicers like Cura, OrcaSlicer, and PrusaSlicer offer different support strategies, and the worse the auto result looks, the more manual placement adjustment pays off. Thin hair tips and fingertips need support, but protecting clean surfaces like cheeks and outer thighs by shifting contact elsewhere makes downstream work significantly easier.

Summarized as quick Q&A, the recurring pain points are predictable: Layer lines persist? Step through grits without skipping and check with primer between rounds. Support marks too visible? Relocate placement to back and shadow surfaces before sanding. Paint not sticking? Re-wash and re-prime. Brush marks? Thin the paint and space out coats. Drying issues? Manage by not touching. Split-line mistakes? Convert the seam into a meaningful design line. None of these are dramatic tricks, but accumulated attention to these fundamentals is what raises a figure's quality.

Recommended Setups for Your First Figure

The Resin Route

If indecision over equipment keeps stalling your start, resin printing plus water-based acrylic paint is the combination most likely to get you to a finished result you are happy with. When the goal is a small, high-detail figure, the face, hair strands, and fingertips carry the impression directly, and this route makes it easier to trace problems back to their source when things go wrong. Starting with water-based acrylics also keeps the painting process approachable: brush-friendly, with natural stopping points.

For the very first figure, a bust of around 7 cm has a remarkably high success rate. The small size keeps print time and material use low, while still walking you through the full sequence: support removal, washing, surface prep, priming, and painting. Because the face and hair dominate the piece, the sense of accomplishment when it comes together is strong. Starting with a bust rather than a full-body standing figure makes it clearer both what is difficult and what delivers the most visual impact.

The minimum tool set is more compact than expected: resin printer, resin, basic wash and post-cure supplies, nippers, sandpaper, primer, brushes, and water-based acrylic paint. Sandpaper from 400 to 1000 grit covers the first figure's needs. Keeping painting brush-based at this stage avoids the upfront commitment to a full airbrush kit, which eases the learning curve. For software, Blender (free) handles model adjustments, and PrusaSlicer or a compatible mSLA slicer handles slicing. Exact pricing for a full kit varies widely depending on printer choice and wash/cure setup, so rather than quoting specific numbers, focusing on which items to prioritize gives more actionable guidance.

The FDM Route

FDM plus heavy primer suits anyone aiming at chibi-style or larger figures. For low-proportioned characters, mascot body types, or display pieces where the base is part of the presence, the strategy is not to erase every layer line but to build a solid primer foundation and unify the impression through painting. This route works best when silhouette and presence matter more than granular surface detail.

The strength of this approach is that the print-to-cleanup workflow is more intuitive and supports rapid iteration. FDM gives ground to resin on fine detail, but committing to a thicker primer layer and sanding it smooth brings the piece within reach of completion even for beginners. It pairs especially well with subjects where charm comes from the silhouette: rounded hairstyles, simple clothing, deformed-proportion faces.

The minimum tool set: FDM printer, PLA filament, nippers, 400-1000 grit sandpaper, primer, putty, paint, and brushes. Water-based acrylics work well here too. Adding a spray can for larger surfaces makes coverage faster; spray from about 30 cm away in 2-3 thin passes to keep the surface smooth. Slicer options include Ultimaker Cura, OrcaSlicer, and PrusaSlicer, all free. As with the resin route, confirmed pricing for a full kit was not available in a reliable range, so prioritizing which tools to acquire first is more useful than quoting numbers.

Checklist: Completing Your First Figure

For the first figure, finishing without getting stuck matters more than finishing well. The most effective strategy is to break the project into small stages rather than jumping straight to a full-size print. In my experience, the most common reason figures go unfinished is not choosing the wrong method but trying to nail the final piece on the first attempt.

The progression that works most reliably:

1. Run a small test print

Print just the face, hair, or a section of the arm first. This reveals how detail comes out and where support marks land. If you chose a bust, the test itself may end up being the final piece.

1. Review splits and support placement

If the test shows marks on prominent surfaces, check whether they can be routed to the back or into shadow before moving on. Adjusting placement is almost always faster than sanding away the damage.

1. Move to the final print

Fix only the issues the test revealed, then print the real thing. Prioritizing post-processing ease over maximum print quality for the first figure raises the completion rate.

1. Test-paint on spare parts

Before touching the main figure, try primer adhesion, paint opacity, and sheen on cut-offs or reject prints. This single step prevents a surprising number of main-body mistakes.

The next-action list is actually short. Decide the method based on size and detail needs, and buy surface prep supplies before paint. Figure making tempts you into color selection early, but the tools that push quality upward are the unglamorous ones: primer, sandpaper, nippers.

Appendix: FDM vs. Resin Printing Comparison Table

Characteristics by Method

When unsure which method to choose, looking beyond print precision alone to where you'll spend effort after printing makes the decision clearer. FDM is "a method that's good at producing stable, larger forms," while resin printing is "a method that's good at producing clean surfaces and fine details." Here's a focused comparison on the points where differences show most for figure making.

Resin looks better on paper for appearance alone, but FDM has the simpler path to completion. Conversely, if you want hair strands and facial details as clean as possible before painting, resin gives you an easier transition into paint work. Here's something that often surprises people: the beginner stumbling block isn't "print quality" itself but which post-processing workflow fits on your desk.

Quick Decision Guide by Use Case

To simplify the choice further, decide based on "what kind of piece, to what finish level, with which workflow you're willing to accept." I've found that rather than poring over spec sheets, picturing the specific first figure you want to make and matching it prevents more mistakes.

In my testing, the important first decision isn't just "do I want high detail?" If you have time for sanding and smoothing, FDM works; if you want surfaces ready faster including wash and cure steps, resin works -- that framing is very practical. It's not that one is better; the center of gravity for work differs based on your target finish.

If you're still torn, starting your first figure with FDM to learn the process and expanding to resin from your second piece onward is a perfectly valid path. Conversely, if you're set on small-scale facial fidelity from the start, entering through resin reduces the gap between expectation and result. Either way, aligning your finishing approach to the method's strengths significantly raises satisfaction with the completed piece.
