Why 3D Printing Changed Tabletop Gaming
Five years ago, a single Warhammer squad cost $40–60. A full D&D monster collection ran hundreds of dollars. Today, a resin printer and a spool of quality resin let you produce an entire army at home for the cost of materials alone. The tabletop gaming community has embraced 3D printing faster than almost any other hobby group, and the results are stunning.
But printing miniatures is a specific skill — it's not the same as printing a phone mount or a calibration cube. The tiny details, thin features, and small tolerances require different approaches from general FDM printing.
Resin vs FDM for Miniatures
Resin: The Detail Champion
For miniatures under 50 mm tall, resin printing is unmatched. A 6K+ LCD resin printer produces details at 30–50 micron resolution — individual belt buckles, facial expressions, weapon engravings all come through cleanly. This is the same resolution range as commercial miniatures from Games Workshop or Reaper.
- Best resin types: standard gray or opaque resin for visibility; ABS-like for durability in gaming
- Build volume: most miniatures fit easily on even small resin printers
- Post-processing: wash in IPA, UV cure, remove supports
FDM: The Budget and Scale Option
FDM can't match resin's fine detail, but it handles larger models (75 mm and above) well and costs less per print. A 0.2 mm layer height on a well-tuned FDM printer produces recognizable miniatures with decent detail. Key optimizations:
- Use a 0.2 mm nozzle instead of 0.4 mm — doubles resolution
- Print at 0.08–0.12 mm layer height for maximum FDM detail
- Slow down outer walls to 20–30 mm/s
- Use adaptive layer height: fine layers on detailed upper sections, coarser on the base
Slicing Miniatures
Orientation
Resin miniatures print best tilted 30–45 degrees from vertical, rotated so the least-detail surfaces face the build plate. This reduces support contact on faces, weapons, and other critical details. The "hero face" — the most visible angle of the miniature — should always point away from supports.
Supports
For resin: use light or medium supports with 0.4–0.5 mm contact tip diameter. Avoid heavy supports on detail surfaces — they leave marks that are hard to sand clean on tiny features. Most slicers (Lychee, Chitubox) have "tree supports" or "branch supports" that minimize contact points while still holding overhangs.
For FDM: standard supports work but leave rough surfaces. Consider soluble support filament (PVA or HIPS) if your printer supports dual extrusion — it dissolves away cleanly, leaving no scarring.
Hollowing
Resin miniatures larger than 25 mm should be hollowed to save material and reduce suction forces during printing. Wall thickness of 1.5–2 mm is standard. Always add drain holes at the bottom — trapped resin causes print failures and makes cleaning harder.
Scaling and Proportion
Most downloadable miniatures are designed at 28–32 mm "heroic scale" (the tabletop standard). When scaling:
- Print a test miniature at intended scale before committing to a batch
- Check that weapon tips, thin limbs, and small details survive at your scale
- Scale down by no more than 50% before detail loss becomes unacceptable on resin
- FDM miniatures scale up better than down — larger prints retain more detail
Painting Prep
A well-printed miniature needs minimal prep before painting:
- Remove all supports carefully with a sharp blade or flush cutters
- Sand support marks with 400–600 grit sandpaper (resin) or a needle file (FDM)
- Wash resin prints in soapy water after curing to remove IPA residue
- Prime with a spray primer (gray or white) before applying acrylic paints
The primer step matters more than most beginners realize — bare resin and bare FDM surfaces both resist paint adhesion. A good primer coat gives the paint something to grip.
