| Format | Textures | Colors | Best for |
|---|
| OBJ | Yes | Yes | Full-color 3D printing (Mimaki, Stratasys). Universal format. |
| STL | No | No | Standard FDM/SLA single-color printing. Most slicer-compatible. |
| GLB | Yes | Yes | Sharing, web viewers, AR/VR. Compact single file. |
| 3MF | Yes | Yes | Multi-material and full-color printers. Modern recommended format. |
When uploading OBJ files, always include the .mtl material file and all texture images (.png, .jpg) in the same ZIP archive. Without these, your model uploads without colors or textures.
DICOM and LAS/LAZ files show a special configuration dialog after upload where you can adjust import settings like density thresholds and reconstruction quality. See Uploading files for details.
- For full-color printing (Mimaki, Stratasys): Upload OBJ+MTL or 3MF. Export as 3MF or OBJ.
- For single-color printing (FDM, SLA): Upload any format. Export as STL.
- For sharing or web viewing: Export as GLB.
- For medical data: Upload DICOM files directly.
- For terrain/survey data: Upload LAS or LAZ files.
