Check scale in millimeters before exporting
To confirm your 3D CAD file is the correct size, always check your model's dimensions in millimeters before exporting. Our system interprets files in millimeters by default‚ so if your CAD file is in inches or centimeters but exported incorrectly, your part may print at the wrong scale.
Here's how to avoid that:
-
Verify unit settings in your CAD software (mm recommended)
-
Use measure tools to double-check key dimensions
-
Export as STL or STEP with units set to millimeters
-
Reopen the exported file in a viewer (like Fusion 360, Meshmixer, or Cura) to confirm it appears at the correct scale
If you're still unsure, ask us to verify
