Are the generated 3D models printable?

Yes. Draftr generates solid geometry intended for FDM printing and exports STL files that work in Cura, OrcaSlicer, PrusaSlicer, Bambu Studio, and other slicers.

Can I edit the model after it's generated?

Yes. The output is parametric CAD with an editable history, so you can change dimensions and features and re-export instead of regenerating from scratch.

Do I need CAD experience?

No. You can generate and refine models entirely by describing what you want, though direct modeling tools are there when you want precise control.

AI 3D Model Generator — Printable, and Actually Editable

Draftr's AI 3D model generator turns a description into a printable 3D model — and unlike most generators, the output is real, editable CAD geometry rather than a frozen mesh. Generate a model, refine it with more prompts or direct tools, and export an STL that drops straight into your slicer.

Built for 3D Printing

Manifold, printable geometry. Draftr models solids on the OpenCascade kernel, so exports are FDM-friendly — sensible walls, clean surfaces, real dimensions.
STL export. Output works in Cura, OrcaSlicer, PrusaSlicer, Bambu Studio, and any modern slicer.
Millimetre-accurate. Describe sizes directly and the model respects them, so fit-critical parts print right.

What You Can Generate

Functional parts — brackets, clips, knobs, spacers, mounts, adapters.
Enclosures and lids sized to a board or device.
Replacement parts for broken or missing components.
Print-in-place fixtures, organizers, and hooks.
Prototype bodies you'll keep refining across edits.

Generate → Refine → Print

Describe the model in plain language, including approximate measurements when fit matters.
Draftr generates a parametric solid and shows a live preview.
Refine with follow-up prompts (Quick Edit) or direct tools — every change is a versioned step.
Export STL and slice it for your printer.

Why "Editable" Matters

A test print almost never fits perfectly the first time. With a mesh generator, a tweak means regenerating and hoping. With Draftr, you just change the dimension — "open the bore to 6.2mm", "add 0.3mm clearance", "thicken the wall" — and re-export. The model remembers how it was built, so iteration is fast and predictable.

One Tool, From Idea to Printable Solid

Draftr is a native desktop app for macOS and Windows. The geometry runtime ships inside the app, so it works offline right after install — no cloud round-trip to model a part. Every AI generation and edit lands as a versioned step in a non-destructive draft stack, so you can go back, change an earlier operation, and rebuild everything downstream without losing your parametric intent.
