Quick Answer: How Do You Print Good Miniatures?
The workflow in 5 steps:
- Get a resin printer (detail is the whole point) — see best resin printers.
- Slice with proper settings: 0.03–0.05mm layer height, ~2s layer exposure (tune to your resin), 3–4s bottom exposure.
- Orient the model and add supports (automatic “light” support type works well).
- Print, then wash in IPA (or wash station) — carefully remove supports while the part is still soft-ish, then cure under UV.
- Post-process: sand nubs, prime with a miniature primer, and paint.
For D&D/Warhammer-scale (28–32mm), resin beats FDM every time on detail. See resin vs FDM for details.
Step 1: Resin vs FDM for Miniatures
FDM can print large terrain, props, and chunky minis, but layer lines are visible and fine detail (faces, weapons, jewelry) gets mushy.
Resin is the clear winner for anything tabletop-scale: smooth surfaces, crisp detail, and excellent paint adhesion. Choose resin for figures. Use FDM for big terrain/bases.
Check before buying: miniatures orient vertically and need good layer accuracy. The Saturn 4 and higher machines deliver.
Step 2: Choose the Right Resin
| Resin Type | Best For | Notes |
|---|---|---|
| Standard gray/8K | General minis | Great detail, cheap |
| Standard black/white | Detail showcase | White shows paint well |
| Water-washable | Ease of cleanup | Wash in water not IPA |
| ABS-like / tough | Durable, playable minis | Less brittle, better for gaming |
| Low-odor | Indoor printing | Less smell, pricier |
| Engineering (accurate) | Casting/jewelry | See resin guide |
For your first minis, a standard gray 8K resin is the safe, cheap, excellent-detail starting point.
Step 3: Slice Settings That Matter
In your slicer (e.g., Chitubox, Lychee, slicers from Elegoo/Anycubic):
- Layer height: 0.03–0.05mm. Lower = finer detail, longer print. 0.05mm is fine for most; go 0.03mm for hero/display minis.
- Exposure time: tune to YOUR resin (start with the brand’s recommended ~1.8–2.5s for normal layers, 25–40s bottom). Over-exposure = bloated detail; under = delamination.
- Bottom layers: 4–6, with longer exposure for bed adhesion.
- Lift speed / retract: leave near default; slow retract improves quality on detail.
- Anti-alias: on (smooths edges).
Run a validation print (e.g., a calibration cube with pillars/holes) before your first real mini to nail exposure. This saves ruined minis and wasted resin.
Step 4: Orienting & Supports
Orientation: usually 30–45° tilt for figures. Flat-on-top minis warp and lose detail; 45° balances detail and support burden. Never print a figure flat on its back — it’ll trap resin and show layer worst.
Supports:
- Use automatic supports at “light” or “medium” and let the software do the work.
- Manually add supports near heavy overhangs (shelves, capes, weapons) — automatic sometimes misses critical spots.
- Support contact points should touch non-critical areas (backs, undersides) to avoid scarring faces.
More on supports: supports are where newcomers ruin what would otherwise be a great print. A few rules that save models: tilt figures ~30-45° so overhangs (arms, capes, weapons) get support without piling supports on the face; land contact points on natural hiding spots (under capes, on the back, under feet) rather than the middle of a face; let auto-supports run first, then add a few manual ones on heavy overhangs; use beefier supports for heavier models and light tips for delicate weapons so you don’t snap them removing; and remove supports right after washing, while the part is still a bit soft — fully cured resin makes supports brittle and riskier to clip. Mastering supports is the real difference between great minis and ruined ones, and it’s a skill that improves with every print.
Step 5: Post-Processing (Wash, Cure, Finish)
- Remove from build plate carefully with a scraper.
- Wash: soak/rinse in isopropyl alcohol (or water for water-washable) in a wash-and-cure station. Agitate gently.
- Remove supports — do this while the part is still in the wash/half-cured state when supports are more pliable; use flush cutters.
- Cure under UV (2–5 minutes typically, don’t over-cure or it gets brittle).
- Finish: sand support nubs with fine grit, fill gaps with green stuff/milliput if needed, and prime with a rattle-can miniature primer before painting.
Recommended gear: an all-in-one wash-and-cure station (see resin printers) makes this 10x easier. Wear gloves throughout.
Pro Tips for Cleaner Minis
- Chamfer/bevel support bases to ease removal.
- Slow down — for detail minis, don’t rush with faster resins unless tuned.
- Consistent temperature (~20–25°C) — cold resin changes exposure needs. Heat resin to a stable temp for reliable results.
- Filter and reuse resin from the vat — keeps detail crisp.
- Print in batches — use the build volume for whole squads at once.
Where to Get Miniature Models
Your resin workflow is only as good as your source files. Here’s where to find great minis:
- MyMiniFactory: premium, curated, and full of miniature-focused creators. Heavyweight for D&D, Warhammer-style, and busts. Many creators license files for 3D printing.
- Hero Forge: web-based modeler for custom tabletop miniatures — make your exact character, then export. Perfect for player minis.
- Patrons / sub-tribes: many mini designers (Loot Studios, RN Estudio, M3DM, and more) run Patreons where you get monthly model packs — an affordable way to build a large library fast.
- Thingiverse / Printables / MakerWorld: free libraries with plenty of minis, terrain, and props. Quality varies — curate carefully.
- Kickstarter model bundles: frequent mini-STL campaigns with huge collections at good value.
A key term to learn: ‘commercial license.’ Some premium minis restrict selling physical prints. If you want to sell minis (see business ideas), make sure the pack or individual file explicitly allows commercial printing — many premium creators sell both hobbyist and commercial licenses.
Painting: From Bare Resin to Tabletop-Ready
It’s worth noting: a well-painted mini sells for multiples of a raw print. The basic pipeline for tabletop-quality painting:
- Prime: a light coat of miniature primer (spray or airbrush). Fills micro-texture and gives paint something to grip. Gray or white primer is a solid start.
- Base coat: block in the main colors. Thin your paints slightly; multiple thin coats beat one thick one.
- Shade/wash: apply a dark wash into the recesses to add depth and definition quickly.
- Layer/highlight: a lighter layer on raised areas, then edge highlights. This is where minis pop.
- Finish: a matte varnish protects the paint for handling and play.
You don’t need a pro airbrush setup for good tabletop results — brushes, a wet palette, and quality miniature paints go a long way. If you’re selling, offering painted versions (or painting as a service) is a real up-sell, but it’s a separate skill from printing. Master raw prints first, then add painting as a value-add.
Troubleshooting Common Miniature Print Failures
Here’s what tends to go wrong and how to fix it:
| Failure | Likely Cause | Fix |
|---|---|---|
| Mushy/bloated detail | Over-exposure | Lower normal-layer exposure; run validation |
| Dimensional inaccuracy | Orientation/exposure layer shift | Re-check orientation, calibration |
| Missing/under-exposed supports | Support params too light for weight | Increase support density/size |
| Parts stuck to FEP | Under-exposure or too much bottom exposure | Tune; ensure FEP tension |
| Layer delamination | Too-low exposure or temp | Increase exposure; stabilize temp |
| Warping/tilted base | Poor support of a cantilevered part | Add a solid raft/base supports |
| White residue after wash | IP contamination / washing | Change IPA; dry fully before curing |
| Resin cures on model | Over-curing | Reduce cure time; don’t over-UV |
The fastest way to reduce all failures: validate your exposure with a calibration print, keep the resin at a stable ~20-25°C, and don’t rush the support settings. Once your baseline is right, failures become rare and your mini prints dramatically improve.
Getting the details right — resolution and orientation: two factors decide whether your heroes look crisp or soft. On resolution: the printer’s pixel size (set by the LCD) determines how fine a detail it can render — 4K on a small bed gives fine detail per mm, 8K is better, and 12K (Saturn 4, M5s) is enough for jaw-dropping detail on 28-32mm minis. In practice, layer height (0.03-0.05mm) and exposure tuning matter as much as pixel count — a well-tuned 8K beats a poorly-exposed 12K every time. On orientation: tilt ~45° so faces and weapons are angled up (printing against gravity hides support-pothole artifacts), minimize trapped resin cavities by hollowing the model and adding drain holes, and print the most-detailed surfaces facing up where they’re cleanest. Master both and your minis will look sculpted, not printed — a further lever is choosing the right resin for the part.
Going Pro: Selling Your Miniature Prints
Once your quality is consistent, selling minis is a real business. Quick pointers from our business guide:
- License-check everything. Confirm each model’s file allows commercial printing before you sell physical copies.
- Offer painted options — buyers pay substantially more for a finished, painted mini than a raw resin print. Build painting skill or partner with a painter.
- Sell digital too — listing your own designed STLs on MyMiniFactory/Cults generates passive income with zero shipping.
- Niche down — a recurring tabletop game, a specific creature line, or custom heroes outperforms generic “random mini” listings.
Consistent print quality plus a clear niche is the formula. Resin miniatures are one of the most accessible and profitable 3D printing businesses — the detail resin provides commands real demand.
FAQ
Is FDM ever OK for miniatures?
For large terrain, bases, and chunky display pieces, yes. For 28–32mm detailed figures, resin is worth the extra setup.
Do I need a wash-and-cure station?
Strongly recommended for miniatures. Manual washing/curing is doable but slow and inconsistent across batch prints.
What layer height gives the best detail?
0.03mm is excellent for hero minis; 0.03–0.05mm covers everything well. Sub-0.03mm gives marginal gains for much longer prints.
Why is my miniature mushy/bloated?
Almost always over-exposure. Reduce normal-layer exposure time and re-run a validation print.
How do I get clean surfaces with no support scars?
Angle models so supports hit hidden surfaces, use fine support tips, and spot-fill with green stuff before priming.
The Bottom Line
Resin is the way for quality minis: get a high-resolution resin printer, tune exposure with a validation print, orient at 45°, use automatic-plus-manual supports, then wash/cure and finish. It’s a reliable, repeatable workflow once you’ve got your settings dialed in.
