Archive formats
Upload ZIP, RAR, or 7Z files and we automatically extract them. We find the 3D files inside along with any associated textures and materials.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.
Format recommendations
- 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.
