STL export
Generate an STL after export preflight checks.
QR CODE TO STL
Convert a QR code into an STL model
Build QR geometry from your content, inspect it in 3D and export an STL file after model preflight. The workflow is designed for makers who need more than a flat QR image.
The current generator runs in your browser. ScanSafe provides guidance, not a guarantee that every physical print will scan.
What you can do
Convert a QR code into an STL model
Physical sizing
Control overall size, base thickness and QR relief or engraving depth.
Topology visibility
Review component-level topology health before downloading.
STL HANDOFF CHECKLIST
Use STL when a simple mesh handoff is the priority
STL is widely supported, but it mainly carries surface geometry. Treat the slicer import as a dimensional and mesh check rather than assuming richer object semantics will survive.
Confirm millimeter scale
Verify the imported width and height in your slicer before printing.
Inspect the QR face
Look for merged or missing module features in layer preview, especially on dense codes.
Check the base
Raised and Recessed designs need enough base thickness for the selected feature depth.
Choose 3MF when structure matters
If your workflow benefits from richer package information or object roles, compare the 3MF export instead.
How this workflow works
From QR matrix to printable triangles
ModuQR converts the QR matrix into physical module geometry instead of tracing a screenshot. The builder preserves the relationship between QR modules and the chosen physical size, then builds the base and Raised or Recessed features in millimeters.
Check the model before STL export
The export path runs preflight checks for usable meshes, dimensions, invalid coordinates, triangle counts and component topology. ScanSafe also evaluates the physical QR against the active nozzle and layer-height profile so you can spot a model that may be too dense at the current size.
Use the STL in your slicer
STL is widely supported across common 3D-printing workflows. ModuQR does not pretend to be a slicer: print time, filament usage, supports and machine-specific behavior remain decisions for your slicer and printer profile.

Frequently asked questions
Is the exported STL in millimeters?
The model is designed around millimeter dimensions in the builder. Your slicer should interpret the imported geometry at the dimensions shown by the tool.
Can I make a Recessed QR STL?
Yes. Choose Recessed in the Print step to create engraved QR geometry with a preserved material floor.
Does the STL export join every touching part into one boolean shell?
No. Current topology checks are per component mesh. Touching components are not claimed to be one boolean-unioned manifold shell.
