Name a supported form, then add dimensions and wall thickness. Prompt2STL turns those constraints into parametric geometry.

From sentence to slicer
Three checks between
an idea and the print bed.

Check bed fit, minimum wall thickness, watertightness, and likely support needs before opening a slicer.
Leave with a real STL
Download a closed mesh that standard slicers can open. We also keep your material and setup suggestions beside it.
Built around the physical result
A pretty mesh is not the same as a printable one.
General 3D generators optimize for appearance. Prompt2STL starts with measurable constraints: is the mesh closed, does it fit the selected build volume, and is the requested wall thick enough?
- Closed meshFaces, finite vertices, and manifold edges are checked at runtime.
- Wall checkThickness is compared with directional material guidance.
- Bed fitDimensions are checked against the printer you selected.
- Support hintSteep overhangs are flagged before slicing.

Honest first release
Focused forms first.
Arbitrary objects later.
This MVP is a prompt-guided parametric modeler, not a general-purpose text-to-anything AI. It currently handles planters, open containers, trays, rings, tokens, and cylinders because those forms can be made reliably printable in-browser.
Free-form characters, organic sculptures, and multipart mechanisms need a generative model plus a much deeper repair pipeline. We would rather show a clear boundary than give you a broken STL.
Before you export
Questions from the print bench.
Can I actually 3D print the downloaded model?
Prompt2STL exports checked STL geometry for supported forms. Import every file into your slicer, verify orientation and toolpath, and treat the print-card values as directional estimates.
What kinds of prompts work today?
Simple functional forms: planters, cups, trays, rings, spacers, tokens, coins, discs, pegs, and cylinders. Include dimensions such as “80mm wide, 120mm tall, 2mm walls” for the best result.
Why not generate every kind of object?
General text-to-3D models often need topology repair, thickness work, scale correction, and support planning. This MVP starts with forms it can make predictably watertight and dimensionally useful.
Is my prompt sent to a server?
No. The prompt parser, geometry generation, checks, preview, and STL export run entirely in your browser. Refreshing the page clears the current model.
Should I choose STL or 3MF?
STL has the widest slicer support and is available in this MVP. 3MF can retain units and richer print metadata, so it is a sensible next export format for the product.
