AI STL Generator

AI STL Generator creates printable 3D models from text descriptions or 2D images such as photos, sketches, concept art and logos. It is built for 3D printing hobbyists, makers, tabletop gamers, designers, print shops and small studios who want ready-to-print files without modelling in Blender or CAD software. Outputs target FDM and resin printers and load into slicers like Bambu Studio, Cura, PrusaSlicer and OrcaSlicer.

A user types a prompt of up to 800 characters or uploads one or more JPG or PNG images, with several angles improving the reconstruction. Options include a Basic, Pro or Ultra detail model, STL or 3MF output, an A-pose or T-pose for characters, and scaling to an estimated real-world height. The AI builds the mesh, repairs its topology, shows an in-browser 3D preview and offers the file for download.

Every model goes through a printability check for non-manifold edges, inverted normals and zero-thickness walls, and the repair step seals the mesh and adds a flat base for bed adhesion. A remesh tool adjusts mesh density, simplifies polygon counts and flattens the base before export. The site also offers an AI miniature generator, image to 3MF, SVG to STL and STL/3MF converters, and STL, 3MF and general 3D viewers.

The free plan gives 5 check-in credits per day for the Basic models, with output limited to non-commercial use. Maker costs $7.99 per month on annual billing for 200 monthly credits, and Pro costs $19.99 per month annually for 500, both with advanced models and commercial rights. One-time credit packs that never expire are also sold. The generate button lists 5 credits per model, and Ultra detail adds 5 more.
