Format	Extensions	Textures	Vertex Colors	Multiple Objects	Notes
Wavefront OBJ	`.obj` + `.mtl`	Yes	No	Yes	Most common. Include .mtl and texture files in a ZIP.
Stereolithography	`.stl`	No	No	No	Geometry only. Widely used by 3D printers.
3D Manufacturing	`.3mf`	Yes	Yes	Yes	Modern format with embedded colors and materials.
Autodesk FBX	`.fbx`	Yes	No	Yes	Common in game and animation workflows.
Stanford PLY	`.ply`	No	Yes	No	Point cloud and mesh format with vertex colors.
glTF / GLB	`.gltf`, `.glb`	Yes	No	Yes	Web standard. GLB bundles textures in one file.

VRML	`.wrl`	Yes	Yes	Yes	Legacy 3D web format.
DICOM	`.dcm`, `.dicom`	No	Yes	No	Medical imaging (CT, MRI). See DICOM medical scans.
LAS / LAZ	`.las`, `.laz`	No	Yes	No	LiDAR point clouds. See LiDAR point clouds.

Export formats

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.

Archive formats

Upload ZIP, RAR, TAR, TAR.GZ, or TGZ files and we automatically extract them. We find the 3D files inside along with any associated textures and materials.

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 uploads open a DICOM Segmentation dialog where you define tissue density (Hounsfield) ranges to split the scan into separate 3D parts. Pick a preset (Standard, Head, Simple, or Dense Only) or set custom segments before analysis. 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.
