How to Use a 3D Printer for Miniatures and RPG

Getting started with 3D printing can look like a five-headed hydra, especially when we think about the amount of work it takes. But fear not, this guide breaks down everything you need to know on how to use a 3D printer—whether you’re crafting a hero for your tabletop or an entire RPG scene. Let’s dive in!

Choose Your Poison – I Mean, Printer.

There are two main types of 3D printers: Resin and FDM, or FFF (Fused Deposition Modelling and Fused Filament Fabrication, respectively). Both can work for miniatures and terrains, but each one has specific strengths.

Resin Printers: These are your go-to for high-detail miniatures, thanks to their smooth surface finish and ability to capture fine details. Because of their precision, resin printers are typically favored for RPG miniatures and character models.

FDM Printers: These are ideal for people that are starting to understand how to use a 3D printer. Additionally, it is great to print larger pieces, like terrain, statues, or scenery for RPGs. They build objects layer-by-layer using filament, making them cost-effective and versatile for larger prints.

Roll For Initiative

Once you have chosen your printer and model according to your needs and budget, be sure to follow the fabricants’ manual.

Also, there are many free resources online that offer beginner-friendly miniature files that are compatible with resin or FDM. Sooo… have you checked our freebies yet? You could also consider licensed options from creators or studios (as in Loot Studios) that

specialize in RPG miniatures.

Prepare the Printer

For Resin Printers: Pour the resin into the printer’s vat, and make sure the resin is compatible with your printer type. Resin is UV-sensitive, so always use gloves, mask and work in a well-ventilated area.For FDM Printers: Insert the filament and ensure it’s feeding smoothly through the extruder. FDM printers are generally simpler and safer to handle.

Printing & Post-Processing

Resin Prints: Once your print finishes, carefully remove it from the build plate using a scraper. Clean your miniature with isopropyl alcohol to remove any excess resin, and remove supports carefully with clippers. Most resin prints need a post-curing step to fully harden. Use a UV curing box, or place the miniature in sunlight to achieve a proper cure.

FDM Prints: FDM prints are usually good to go right off the printer, though you may need to remove the supports first. FDM prints don’t require curing, but you might want to prime and paint them for a polished look.

Final Thoughts

With these basics, you’re ready to bring your RPG world to life. Just remember:

Start Small: Test out different settings with small objects to avoid wasting resin or filament.

Safety First: Resin can be toxic; always use gloves and masks when handling it, and be sure to work with it away from other people and pets. Keep FDM printers in a well-ventilated space.

One Print at a Time:

Mastering how to use a 3D printer takes patience and practice. Don’t worry if your first few prints aren’t perfect—you’ll improve over time!

Whether you’re aiming to craft a small army of miniatures or an entire dungeon scene, both resin and FDM printers offer endless possibilities. Here are just some ideas of the best resin 3D printers for beginners that we’ve gathered. Hope it helps!
