Supported file formats

Import formats

When uploading an existing part into an app, the following file formats are accepted:

STL, STEP, OBJ, 3MF

File size limit

Any imported model larger than 5MB will be automatically downsampled to improve performance.

Export formats

All apps export print-ready files in the following formats:

  • STL – the most widely supported format for 3D printing. Works with virtually all slicers and printer software.
  • 3MF – a newer, richer format that preserves color, scale, and orientation data. Recommended if your slicer supports it.

Which format should I use?

Use 3MF if your slicer supports it – it carries more information and reduces the chance of errors. Use STL if you're unsure or if your workflow requires it.
