Browser-first core
QR creation and model generation are designed to run in your browser. The core builder does not require a ModuQR cloud account.
3D QR CODE GENERATOR
Create a QR code as a real 3D object
Turn a URL, WiFi network, contact card, message or other QR payload into printable geometry. ModuQR combines live 3D preview, Raised or Recessed geometry, template options and ScanSafe guidance in one browser-based workflow.
The current generator runs in your browser. ScanSafe provides guidance, not a guarantee that every physical print will scan.
BUILT FOR REAL WORKFLOWS
Useful checks without pretending the browser can guarantee a print
ModuQR keeps the core workflow fast and transparent: create the QR, inspect the physical model, review technical checks and export without signing in.
No account required
The main generator works without registration, saved cloud projects or a subscription.
ScanSafe stays honest
Digital integrity, physical module sizing and print-oriented checks are useful guidance, not a promise that every fabricated QR will scan.
Exports get checked
STL and 3MF workflows use export preflight and component-level topology checks before the current model is generated.
Core generation is free. Monetization is designed around content and discovery areas, not inside the 3D builder.
What you can do
Create a QR code as a real 3D object
Live 3D preview
Rotate the model and inspect the physical QR before exporting.
Raised or Recessed
Choose QR modules above the base or engraved into the surface.
ScanSafe guidance
Check module size, quiet zone, contrast, geometry and print-profile targets before slicing.
How this workflow works
A 3D-first QR workflow
A normal QR generator stops at PNG or SVG. This tool continues into physical geometry: choose the QR content, tune colors and error correction, select an object template, then set the dimensions that matter for 3D printing. The model updates while you work so the visual result and the print parameters stay connected.
Designed around physical constraints
The same digital QR can behave very differently after it becomes plastic. ModuQR tracks module size, base thickness, relief or engraving depth, quiet zone and component topology. ScanSafe is guidance rather than a print guarantee, but it gives you useful warnings before the model reaches the slicer.
Export for your own workflow
Download STL for broad slicer compatibility or 3MF when you want richer model packaging. A technical model report is also available so you can review dimensions, topology results, ScanSafe status and print-profile information alongside the exported geometry.

Frequently asked questions
Can I generate the 3D QR code without an account?
Yes. The current generator works in the browser and does not require an account to create or export a model.
Does ScanSafe guarantee that every physical print will scan?
No. ScanSafe checks digital and geometric conditions and provides conservative print guidance, but real results still depend on printer calibration, material, slicer settings, surface quality and scanning conditions.
Can I export both STL and 3MF?
Yes. The builder supports STL and 3MF export, with export preflight checks before the files are generated.
