3D QR Code
A broad entry point for teams exploring QR codes as physical objects instead of flat images.
This is the discovery page for the full 3D QR problem space: printable geometry, scanability, physical constraints, and downstream production.
A 3D QR code is not automatically useful just because it is extruded.
Physical QR deployment demands choices about materials, depth, quiet zone, and placement.
Without task-specific guidance, teams end up with attractive models that do not scan well enough to ship.
A single hub into 3D print QR, STL, and scannability workflows.

A task-first framing for teams evaluating physical QR deployment.
FAQ
Practical answers for printable QR, STL output, and real-world scanability.
A 3D QR code is a QR pattern expressed as physical geometry, usually as raised or recessed modules that can be printed, engraved, or embedded.
Usually no. Standard phone cameras can scan them if the geometry, contrast, and lighting make the QR pattern clear.
STL is useful for 3D printing, but SVG and PNG references are still helpful for design review and scan validation.
Real-world workflow
This site is organized around the job you are trying to complete, not around a flat list of file formats.
Understand the physical job the QR code has to perform.
Choose a printable workflow instead of a generic generator path.
Generate STL and reference assets together.
