Abstract
Systems and methods for forming an object using additive manufacturing. One method includes receiving a digital model of the object, predicting a shrinking characteristic or receiving a predicted shrinking characteristic of the object that will occur during thermal processing of the object, once formed, and generating, based on the shrinking characteristic of the object, instructions for forming a raft on which the object will be formed. The instructions for forming the raft are configured to form a raft having a shrinking characteristic that reflects the shrinking characteristic of the object.
