AI 3D Model Generator - Describe It or Show It, Download It, Print It

SliceFoundry is an AI 3D model generator for makers. Describe any object in plain text or upload a reference photo and SliceFoundry's AI generates a downloadable, printable 3D model in seconds. Iterate on your model with follow-up prompts, refine the shape and dimensions, and export a print-ready STL file - no CAD software and no design experience required.

Generate 3D Models with AI

Type a description and get a printable 3D model in seconds. SliceFoundry's AI 3D model generator creates STL files from natural language - no CAD software, no design experience required. Generate brackets, enclosures, figurines, tools, replacement parts, and custom objects on demand. Adjust your model iteratively with follow-up prompts until it's exactly right, then download and print.

Image to STL - Turn a Photo into a Printable 3D Model

Have a reference image instead of words? Upload a photo or sketch and SliceFoundry's image to STL generator uses it as the visual target for the AI - matching the shape, proportions, and key features in your picture. Combine an image with an optional text prompt to lock in materials, dimensions, mounting holes, or callouts the photo can't show on its own. It's the fastest way to go from a picture of a broken part, a 3D print you saw online, or a rough sketch to a downloadable, printable STL file.

Iterate Until It's Perfect

Great parts rarely come out right on the first try - so SliceFoundry lets you refine any model with plain-language follow-ups. Say "make the hole 6mm", "thicken the walls", or "add mounting tabs" and the AI adjusts based on your previous render. Every iteration builds on the last, so the model keeps getting closer to exactly what you need before you export the STL.

Print-Ready Geometry for FDM

SliceFoundry generates parametric geometry intended for FDM 3D printing - real dimensions, sensible wall thickness, and printable solids rather than hollow game-asset meshes. Preview your model right in the browser, spin it around to check the fit, then download a clean STL that drops straight into your slicer.

Who SliceFoundry Is For

Makers who want to generate custom 3D models without learning CAD
Anyone who wants to turn a photo or sketch into a printable STL file
Engineers who need consistent, repeatable, printable geometry
Anyone who wants to go from idea to printed object as fast as possible
Hobbyists who need a one-off bracket, mount, enclosure, or replacement part

Want Full CAD Control? Try Draftr

When you want to design a part precisely by hand instead of generating it from a prompt, Draftr is a desktop CAD application for Windows and macOS that combines AI with organic parametric CAD in an IDE-like workspace. Draftr gives you a complete parametric toolkit - sketches, pads, pockets, fillets, chamfers, patterns, threads, heat-set inserts, and more - alongside AI commands that turn natural language into editable CAD, then exports print-ready STL files. It's the natural next step for makers who outgrow prompt-based generation and want precise, editable, parametric models. Learn more at draftrcad.com.

Generate a 3D model from a text description or a reference image and download a print-ready STL - SliceFoundry handles the hard parts so you can focus on making. And when you're ready for hands-on parametric CAD, Draftr desktop CAD picks up where AI generation leaves off.
