AI STL Generator.comStop settling for generic preset sliders or broken AI meshes. This AI miniature generator turns character art or text into a high-detail tabletop miniature in minutes — analyzed, repaired, and ready to slice on FDM and resin printers.
Scale to estimated height, origin at the base

An AI miniature generator for people leaving preset sliders and generic meshes that look sharp, then fail when the miniature hits the slicer.
| Capability | Modular builders | Generic AI generators | AI STL Generator |
|---|---|---|---|
| Creative freedom | Locked to a fixed library of slider parts | Open-ended, but details are hard to steer | Any miniature style, pose, or creature you can describe or draw |
| Print reliability | Manual posing, and supports are painful to remove | Open shells, floating islands, and slicer errors | FDM checks on each miniature for overhangs, wall thickness, and weak points |
| Mesh integrity | Closed meshes, with tight license limits | Non-manifold edges show up after you download | One click makes the miniature manifold: holes filled, self-intersections merged |
| Time and cost | $8–$15 per model, plus time on the sliders | A subscription, and no repair for print defects | Free to start your miniature, often ready in about 2 minutes |
The only AI miniature generator with slicing checks built in.
Have hero art, or just a miniature in your head? Upload a PNG or JPG, or write a vivid prompt. The AI miniature generator builds a full 360° mesh with armor, expression, and signature weapons.
Text to STL & Image to STL
The printability check looks at the miniature's thin weapons, delicate ankles, steep overhangs, and bed contact, then marks the risk zones on the 3D preview before you spend filament.
Analyze for FDM Printability
Slicers choke on non-manifold geometry. Repair seals open holes, flips inverted normals, fixes self-intersecting shells, and reinforces weak spots so the miniature survives the nozzle and the table.
Repair for FDM Printability
Download the watertight miniature STL and import it into OrcaSlicer, Cura, PrusaSlicer, or Chitubox. Scale the miniature there for 28mm, 32mm, or 75mm display sizes.
100% Watertight STL Export
Use the AI miniature generator for D&D 5e heroes, Pathfinder parties, boss miniatures, and the scatter that fills a battle mat.
Generate the hero miniature a modular builder cannot assemble from its parts list.

Desktop filament printers and resin machines read the same repaired miniature STL.
Repair thickens fragile weapon shafts, closes weak joints, and favors a wide base so the miniature holds on filament printers such as Bambu P1S, X1C, A1, Creality Ender 3, and Prusa MK4.
The same miniature keeps crisp edges and cloth folds that show up under resin curing on machines such as Elegoo Mars, Saturn, and Anycubic Photon.
Ask for a 25mm, 32mm, 50mm, or 75mm miniature base — dungeon stone, hex grid, or dirt — then scale the miniature STL in your slicer to 28mm, 32mm, 54mm, or 75mm.
Slicer errors, reference images, repair, scale, and what you can sell.
Raw AI meshes often ship with non-manifold edges, paper-thin swords, and overhangs that a filament nozzle cannot finish. This AI miniature generator runs an FDM printability analysis and a one-click repair on the same page: thin walls, stability, open holes, and a manifold outer shell. Your slicer settings, filament, and printer still decide the print, so treat the check as the pre-flight, not a promise that every miniature prints on the first try.
Yes. Drop in a PNG or JPG — a commission, a character sheet, generated art, or a sketch. Image to STL reads the silhouette, gear, and proportions and builds a matching miniature. WebP needs to be saved as PNG or JPG first.
Generated miniatures often have intersecting faces, inverted normals, and internal cavities that confuse Cura and Bambu Studio. Repair rebuilds the miniature into a single watertight outer shell with no open boundary.
Those builders join a library of pre-made parts with sliders, so you stay inside their proportions and catalog. This AI miniature generator builds the miniature from a prompt or a picture, so a four-armed gunslinger or an insectoid paladin does not have to exist in a parts list first.
The AI miniature generator downloads a watertight STL at the size it created. Scale the miniature in OrcaSlicer, Cura, PrusaSlicer, or Chitubox to 28mm, 32mm heroic, 54mm, or 75mm. Prompt for a 25mm, 32mm, 50mm, or 75mm base if you want that footprint in the mesh; there is no separate scale dropdown.
Paid subscriptions and one-time credit packs include commercial rights to print and sell the physical miniatures, including at a local game store, on Etsy, or at a convention booth. The Free plan is for personal, non-commercial use. You still have to make sure the miniature does not infringe someone else's trademark. Details are on the pricing page.
Yes. The free plan lets you generate a miniature preview, use Text to STL or Image to STL, and run the FDM printability analysis. Downloads follow the credit rules on your plan.
