Abstract
Toolpath generation for additive manufacturing systems involves operations on polygonal contours derived from a model for additively manufacturing a structure. One aspect involves modifying or creating a model to allow parts to be printed without starting and stopping the printing equipment by generating continuous toolpaths or toolpaths having a reduced number of isolated paths. Another aspect involves modifying a slicing engine to generate a continuous toolpath or toolpath having a reduced number of isolated paths based on a representation of an object to be additively manufactured. Another aspect involves selectively placing the gaps at alternating positions among the sliced layers to create a zippering effect.
