Abstract
A system for three-dimensional printing of an object is provided. The system includes a processor and a non-transitory computer-readable medium communicatively coupled to the processor and storing instructions that when executed by the processor are configured to cause the processor to perform operations including determine optimized build orientation based on the object and one or more user indicated surface quality characteristics, generate a plurality of layers comprising one or more support polygons, each layer of the plurality of layers corresponding to a slice in a three-dimensional (“3D”) printing process, and generate, for each of the one or more support polygons, a corresponding toolpath, wherein a spacing between each generated toolpath is determined based on the user indicated surface quality characteristics.
