Can I 3D print the QR codes generated here?
Yes. Export STL frames with elevated modules, choose your preferred filament, and maintain 0.2 mm or finer layer heights for accurate scanning.
Do you support resin printers and multi-material prints?
We provide STL templates tailored for resin curing profiles and include multi-material ready models with separate QR inlays for dual extrusion.
How do I ensure QR codes remain scannable after printing?
Enable border padding, choose high-contrast colors, and test with our embedded verifier before printing your final STL.
Is the generator really free?
Absolutely. Generate, customize, and download unlimited QR assets without subscriptions or watermarks.
