Text to STL with AI Free 3D model generator
Free. Use your own Anthropic or OpenAI key.
Also from Innerscene: Circadian Lab, a free lighting calculator for room illuminance, melanopic EML, and glare.
Watch how it works
How it works
- 1. Describe it or add a photoType what you want in plain words, with sizes if you know them, or add a photo as a reference. Describe an object or a person.
- 2. The AI builds and checks itThe AI writes an OpenSCAD program for an object, or sets up the character generator for a person. It looks at six rendered views of the result and fixes what is wrong, up to five builds per message.
- 3. Refine and exportThe model opens in the viewer at real size. Ask for changes in the chat, move the sliders, then download it or pick a format from the Export menu.
Why make it with AI here
- The model is built from solid geometry, so the STL is a closed mesh that slicers accept without repair in most cases.
- Every dimension you mention becomes a slider, so a 40 mm bracket can become 55 mm without a new prompt.
- You can measure hole spacing and wall thickness in the viewer before you spend filament.
Prompts to try
Click one to open it in the AI panel, then change the sizes to suit.
Getting an STL out
- Open the Export menu in the viewer.
- Choose STL.
- Load the file in Cura, PrusaSlicer, Bambu Studio or any slicer; it comes in at the correct size in millimetres.
STL stores only triangles: no colour and no units. The file is written in millimetres, which is what slicers assume.
Best export formats: STL, 3MF
Good to know
It is strongest on functional parts built from boxes, cylinders and fillets. Sculpted figures and organic shapes come out simplified.
Cost and privacy
You use your own Anthropic or OpenAI API key. It is stored only in your browser and sent only to that provider, which bills you directly: a model typically costs $0.05 to $0.30 at Standard quality and up to about $1 at Detailed, and Innerscene charges nothing. Your key and prompts are not sent to Innerscene; we record anonymous usage statistics such as the steps used, the model chosen, token counts, a cost estimate and whether a model was made.
