Frequently Asked Questions
What is a 3D Printable QR Code?
A 3D QR Code is a physical, three-dimensional model of a QR code that can be read by smartphone cameras. Our tool translates the black-and-white grid into an STL file format, where dark modules are raised blocks. You can print these on any standard 3D printer for keychains, desk plaques, and business cards.
Can I generate Bulk QR codes for free?
Yes. Many enterprise platforms charge expensive monthly fees for bulk generation. Using SahulatHub, you can paste a list of URLs or text strings, and our client-side script will rapidly generate all QR codes and package them into a single, easy-to-download ZIP file.
Do these QR codes expire?
No. These are "Static QR Codes," meaning the data is permanently encoded directly into the pattern of the image. As long as the destination URL or data remains active, the QR code will work forever. There are no scan limits or expirations.
How do I add my logo without breaking the QR code?
QR codes have built-in error correction. When you upload a logo in our advanced tool, we automatically calculate the maximum safe size and place it centrally, ensuring modern smartphone cameras can still easily decode the surrounding dots.
