Core support questions

Answers to the main follow-up questions.

Can this site turn any file into a 3D printer file? +

No. Open mesh formats can be checked, but images, CAD assemblies, and native DCC scenes may need cleanup or a different tool before STL export.

Which format should I look for before slicing? +

STL is the common print handoff format. OBJ may work when the workflow needs mesh data before a separate print-prep step.

What should I check before printing? +

Check scale, closed geometry, wall thickness, orientation, and whether the model has separate parts that need repair.
