An unorganized point cloud may be created by an optical 3D scanner that scans a physical object, or by computer simulation. The point cloud may be converted into binary raster layers, which encode material deposition instructions for a multi-material 3D printer. In many cases, this conversion&#x2014;from point cloud to binary raster files&#x2014;is achieved without producing a 3D voxel representation and without producing a boundary representation of the object to be printed. The conversion may involve spatial queries to find nearby points, filtering material properties of the found points, looking up material mixing ratios, and dithering to produce binary raster files. These raster files may be sent to a multi-material 3D printer to control fabrication of an object. A user interface may display a preview of the object to be printed, and may accept user input to create or modify a point cloud.
