Slice files (ie. a stack of images) can be imported for 3D reconstruction. Common image formats (such as .Jpg, .Png, .Tiff, and .Bmp) are supported. Slice files typically work best if the greyscale intensity corresponds to material density, as in magnetic resonance imaging (MRI).
Individual bitmaps (one for the primary and secondary materials) can be exported for 3D printing purposes. Currently, these bitmaps are setup to use the following configurations (600 dpi along X-axis, 300 dpi along Y-axis, and 845 dpi along Z-axis) and are saved as one-bit-per-pixel images.
Mesh files can also be saved out as slices where each individual slice represents a boolean intersection between the Shape and Material channels. If saving to a Rhino multimaterial slice file, then the slices will be saved to individual layers for easier processing. STL multimaterials slice files will save each mesh slice as a new .stl file.
Import/Export Voxel Files (.vol)
Volume files (extension .vol) contain relevant information about the voxel configuration (ie. resolution, number of channels, etc.) and the density values attributed to each location in space. Volume files can be imported or exported to/from the stand-alone Monolith application. In addition, volume files can be used in 3rd party applications, such as the Rhino and Grasshopper™ CAD environments. The Monolith plugin for Grasshopper (which is included with the installer) provides features for importing, exporting, and modifying voxel files.
Saving with resources (.lith)
Unlike a volume file (.vol) which only saves the density values of the voxel field, a .lith file will save additional attributes about your current work session. A .lith file will save your layer configurations, including expressions and parameter settings. These files are generally more robust and have the ability to save additional resources along with the file.
