Prescriptive analytics for understanding of out-of-plane deformation in additive manufacturing

摘要

Geometric accuracy control is crucial to fulfill the promise of additive manufacturing (AM). The control of the out-of-plane deformation has been a challenge task for AM due to its complex underlying physics. We have been establishing a generic and prescriptive methodology to represent, predict and compensate 3D geometric deformation of AM built products based on a limited number of test cases. Built upon our previous study, this work aims at developing a prescriptive approach to better understand the out-of-plane deformation due to complex inter-layer interactions. Experimental investigation is conducted to validate the prescriptive model through a stereolithography process.
