Frequently Asked Questions
Is this QR code generator truly 100% free with no expiration?
Yes, 100% free forever. Unlike other websites that deactivate your QR codes after 14 days or demand monthly subscriptions, all standard QR codes generated here are static, direct, and never expire. You get unlimited scans, instant vector SVG/PNG downloads, and full 3D multi-color print files completely free without requiring an account or credit card.
What is a 3D printable QR code?
It is a physical 3D object —such as a table stand, keychain, wall sign, magnet or coaster— featuring an embossed QR code with embedded multi-material colors, ready to print on modern 3D printers using dual filaments.
Can 3D printed QR codes be scanned with any smartphone?
Yes, as long as there is sufficient optical contrast between the base plate and the raised QR pattern. Our live contrast meter alerts you in real-time if chosen colors have insufficient contrast (3:1 minimum ratio recommended).
What is the 3MF file format and why is it better than STL?
3MF (3D Manufacturing Format) is the modern industry standard used by Bambu Studio, PrusaSlicer, OrcaSlicer, and Cura. Unlike legacy single-color STL files, 3MF bundles both the physical geometry and exact filament color assignments in one file without manual alignment.
How do I print the QR code without a multi-material AMS / MMU unit?
You can print it on any standard single-extruder 3D printer by adding a pause command (M600 filament change) in your slicer at the exact layer where the base finishes and the raised QR relief starts.
What are the physical dimensions of the generated objects?
The table stand measures 80×80 mm with a 38° angle. The keychain measures 60×38 mm with a 4.2 mm thickness and ring loop. The wall sign measures 90×90 mm with mounting holes. The magnet measures 70×70 mm with an 8×2 mm cavity. The coaster measures 88×88 mm.
Can I embed my company logo or an emoji in the center?
Yes. You can upload any custom image or choose from popular icons. The tool automatically engages High Error Correction (Level H) so the QR code remains 100% scannable even with the center covered.
Are my links and data uploaded to any servers?
No. All processing —QR generation, 3D mesh building, and 3MF packaging— runs 100% locally in your browser. Nothing ever leaves your computer.
Can I change the destination URL without re-printing?
The printed QR code is permanent. If you want a dynamic destination, use a URL shortener (like Bitly or your own redirect domain) as your link, so you can update where it points anytime.
