List of supported file formats

GrabCAD Print allows you to print from a huge variety of file types. If you’re having trouble inserting a file, please make sure that the software and version are in the list below.

1 All multi-body files are presented as a single body with one texture, for now. Only GIF, PNG, BMP, and JPEG texture files are supported. Color depth must be 8 bits per channel. For formats that support RGB channels this means a depth of 24 bits per pixel. For formats that support transparency as an Alpha channel (PNG only), the RGBA channels result in 32 bits per pixel. Only triangle meshes are supported (i.e. facets with 4 or more vertices are not supported). 

2 Non-standard OBJ files with long lines wrapping around to the next line using a trailing '\' are supported. MTL material files with displacement / tactile texture information are not supported. To print with such textures, use the texture to physically displace the model geometry. For OBJ files with non-standard per-vertex colors the colors are imported if the RGB color channels are represented as floating point numbers in the range [0.0, 1.0].

3 At present 3MF import is available as part of GrabCAD Labs. You can enable it under "File > Preferences > GrabCAD Labs".

4 Body and face colors and textures are supported for 3MF files exported from SolidWorks. Other CAD systems have not been tested for color and texture support. Currently transparency data and assembly structure are not supported.
