Why this STL QR prints better
The generator is still fast, but the output is shaped around printability: module size, quiet zone, geometry, and production handoff.
The tool estimates physical module width before export, so dense payloads are caught before they become failed prints.
Printable QR codes need margin around the matrix. The STL package keeps that scan-critical space part of the model.
The model is generated from the QR matrix rather than a screenshot conversion, keeping raised modules aligned to the code.
Export STL for slicing, then keep SVG or PNG nearby as the clean reference for scan testing and fabrication handoff.

FAQ
Common questions before exporting an STL QR code or sending a 3D printed QR code to production.
Yes. QR codes can be 3D printed when the modules are large enough, the quiet zone is preserved, and the physical part has enough contrast for phone cameras.
It depends on payload density and scan distance. Start around 65-80 mm for a general prototype, then increase width if the module size warning appears.
A 2 mm base with about 1-2 mm of QR relief is a practical starting point for many prototypes. Material and finish can require more relief.
