Text to STL — Turn Descriptions into Print-Ready STL Files

SliceFoundry converts plain-text descriptions directly into printable STL files. You describe the object — its purpose, rough dimensions, key features — and the AI builds a printable solid you can preview in the browser, iterate on, and download as an STL.

If you've ever wanted a custom print but didn't want to learn CAD, this is the gap text-to-STL fills. It's especially useful for parts you only need once — brackets, fixtures, jigs, and replacement components — where modelling in Fusion 360 or OpenSCAD isn't worth the time investment.

What the Text Prompt Should Contain

• The purpose — what the part does and what it attaches to.
• Approximate measurements — overall length, width, height, wall thickness, hole diameters, shaft sizes.
• Mounting features — screw holes, clips, tabs, snaps, posts, pins.
• Orientation hints — which face is the bottom, where the print bed contact should be.
• Material context — if you're printing PLA vs PETG vs TPU, mention it; some geometries need a little more thickness in flexible filaments.

From Prompt to STL in Four Steps

1. Write your description in plain English.
2. SliceFoundry generates the printable solid and shows a live preview.
3. Iterate with conversational prompts — "make the hole 6mm", "round the corners", "add ventilation slots".
4. Export the final design as a binary STL ready for slicing.

Compatible with Every Major Slicer

The exported STL works directly in Cura, OrcaSlicer, Flash Studio, PrusaSlicer, Bambu Studio, and any other modern slicer. SliceFoundry can also generate matching slicer profiles tuned to your specific printer and filament so your first print succeeds.

Common Text-to-STL Use Cases

• Replacement parts for appliances, electronics, and furniture.
• Custom enclosures sized to specific PCBs or modules.
• Print-in-place jigs and fixtures for woodworking and assembly.
• Mounting brackets for cameras, sensors, lighting, and antennas.
• One-off props, ornaments, and gifts.

Prefer Hands-On CAD? Try Draftr

When you'd rather design a part precisely by hand than generate 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. It pairs a full parametric toolset — sketches, pads, pockets, fillets, chamfers, patterns, and threads — with natural-language AI commands, then exports print-ready STL files (and supports STEP-oriented CAD workflows). It's the natural next step once you outgrow prompt-based generation and want precise, editable, parametric models. Learn more at draftrcad.com.
