Workflow
Use a packaged mesh format for a modern print handoff
PurCad creates a real packaged 3MF artifact rather than loose XML or renamed JSON. The file belongs to a specific checked version and can travel alongside STEP or STL when different downstream tools need different representations.
Choose 3MF when the slicer supports it well
3MF is useful for modern print pipelines that expect a packaged mesh container. Confirm the receiving slicer's support and keep the project units and bounds visible. Use STL when maximum legacy compatibility is more important.
Prepare one coherent download set
Select 3MF in Download, optionally add STEP or STL, and create the artifacts from the current version. Multiple files can be downloaded together, keeping the print mesh and mechanical handoff synchronized.
Validate the package in the target application
Open the 3MF in the real slicer and confirm size, body count and geometry. Package support varies by tool; check that the intended object is present and that no import scaling occurred before slicing.
The container cannot guarantee process settings
PurCad exports geometry and basic file structure, not a certified printer profile. Material, support, layer height and strength remain downstream manufacturing decisions. Test the printed result against its functional requirement.
