In addition to the native file format (whatever your 3D modeling program uses) 3D models for printing should be saved or exported for printing, in the STL format (binary or ascii).

	After the part is modeled it needs to be turned into commands the 3D printer can recognize, a step called 'slicing' since it turns the solid shape into a series of paths and printer commands to move and start and stop the extruder, that build up the part layer by layer. The ~~final~~ step in 3D modeling, then, is to save the part in a format that the slicing software can recognize.
