From sketch to 3D print in 5 minutes

3D printing has gotten cheap. The bottleneck is no longer the printer — it's the model. If you're not a Blender wizard, you stare at Thingiverse hoping someone made what you want.

Polyx changes the math. Sketch your idea on paper, scan it with your phone, and you have an STL ready to slice in five minutes.

The workflow

1. Sketch. Paper and pencil work fine. Capture three views if possible: front, side, top. (Single view also works — read on.)
2. Photograph. Decent lighting, plain background. Phone camera is fine.
3. Upload to Polyx. Image-to-3D with the “3D printing” preset. This biases toward watertight, manifold geometry.
4. Export STL. Click the STL toggle in target formats.
5. Slice and print. Cura, PrusaSlicer, Bambu Studio — drop in the STL.

Tips for printable models

• Avoid floating geometry. Our pipeline closes most gaps automatically, but very thin or disconnected parts may fail.
• Mind the scale. Use auto_size in the API or set physical dimensions in the slicer.
• Check overhangs. Polyx doesn't know about your printer's support requirements. Use the slicer's preview to add supports.

Multi-view for higher fidelity

Single-view is fast, but a single 2D photo always loses depth information. For tabletop minis, action figures, and anything with detailed back/sides, use Multi-image to 3D: upload front + side + 3⁄4 view. Reconstruction quality jumps dramatically.

Real example

One of our community members printed an entire D&D character roster — 24 minis — from sketches over a weekend. Total cost: 24 × 30 credits = roughly $25. Equivalent commission price: $480. Time saved: about 100 hours.
