Patent number: 11138352Abstract: An additive manufacturing (AM) system includes a process distortion compensation computing system and an AM peripheral device. The process distortion compensation computing system determines a digital nominal model that represents a physical target object excluding a distortion, and a digital distortion model that represents the physical target object including at least one distortion. The AM peripheral device forms a three-dimensional (3D) physical object based on a digital compensation model. The process distortion compensation computing system also determines a digital skeletal model indicating a predicted change in at least one of the shape and volume of the nominal model, and generates the digital compensation model based on the skeletal model that compensates for the at least one distortion.Type: GrantFiled: June 5, 2019Date of Patent: October 5, 2021Assignee: HAMILTON SUNDSTRAND CORPORATIONInventors: Yanzhi Chen, Qingqing Zhang, Tahany Ibrahim El-Wardany, Ranadip Acharya, Colette Opsahl Fennessy, William K.
