If you’ve been eyeing those incredibly detailed miniatures popping up in your tabletop gaming groups and wondering how people are printing them at home, you’re in the right place. Resin 3D printing has completely changed the miniatures hobby, making it possible to produce figures that rival — and sometimes surpass — commercial injection-molded minis.
Why Resin Over FDM?
You might already own a filament (FDM) printer, and they’re fantastic for terrain, buildings, and larger pieces. But when it comes to the fine detail that miniatures demand — facial expressions, chainmail texture, thin swords — resin printing is in a different league entirely.
Resin printers use UV light to cure liquid photopolymer layer by layer, achieving layer heights as fine as 0.02mm. That’s roughly the thickness of a single human hair. The result is smooth surfaces and crisp detail that FDM simply cannot match at this scale.
Choosing Your First Resin Printer
The market has exploded with affordable options. Here’s what to look for:
- Build volume: For standard 28mm–32mm miniatures, even a small build plate works fine. You’ll typically print 4–8 minis per batch.
- Resolution: Look for an XY resolution of 35 microns or better. Most modern consumer printers hit this mark.
- Light source: Mono LCD screens cure faster and last longer than older RGB screens. Every current-gen printer uses mono.
- Community support: A printer with an active user community means better slicing profiles and troubleshooting help.
Popular starter printers in the $200–400 range deliver excellent results for miniatures right out of the box.
Essential Supplies Beyond the Printer
The printer is just the beginning. You’ll also need:
- Resin: Standard gray or white resin works great for painting. Some hobby resins are formulated specifically for miniatures with better detail and less brittleness.
- Wash station: Isopropyl alcohol (IPA) at 95%+ concentration for cleaning uncured resin off your prints. A wash-and-cure station makes this painless.
- UV cure light: A dedicated curing station or even a UV nail lamp to fully harden your prints after washing.
- Nitrile gloves and respirator: Safety first. Uncured resin is toxic — always wear gloves when handling it and work in a ventilated space.
- FEP film: The transparent film at the bottom of your resin vat will eventually need replacing. Keep spares on hand.
Your First Print: Tips for Success
- Level your build plate carefully. This is the single most important step. A poorly leveled plate means failed prints.
- Use pre-supported files to start. Many STL creators include pre-supported versions. Use these until you’re comfortable adding your own supports.
- Don’t rush exposure times. Use the resin manufacturer’s recommended settings for your printer, then dial in from there.
- Print at an angle. Tilting models 15–30 degrees reduces suction forces and improves success rates.
- Hollow larger models. Saves resin and reduces peel forces. Just remember to add drain holes.
Where to Get STL Files
The miniatures STL ecosystem is thriving:
- Patreon and MyMiniFactory Tribes — Monthly subscriptions to your favorite sculptors. Usually $10–15/month gets you dozens of models.
- MyMiniFactory — One-off purchases and free files from talented creators.
- Thingiverse — Free community models, great for terrain and accessories.
- Loot Studios, Archvillain Games, Titan Forge — Premium monthly subscriptions with full adventure sets.
What’s Next?
Once you’ve got your first successful prints, the real fun begins — cleaning, curing, priming, and painting your miniatures. We’ll cover all of that in upcoming guides.
The barrier to entry for resin printing miniatures has never been lower. For the cost of a few boxes of commercial minis, you can set up a home printing station that produces endless armies, monsters, and heroes for your tabletop adventures.
Welcome to the hobby. Your printer awaits.
