Method and apparatus for strong reduction of shape error due to uncertainty in laser powder deposition-based additive manufacturing process

摘要

A method of optimizing an additive manufacturing (AM) process includes receiving at least one design parameter of an AM process, receiving information related to uncertainty in at least one other parameter of the AM process, Performing uncertainty quantification in an optimization processor, based on at least one design parameter and uncertainty information, to identify a shape error in the object being created, updating at least one design parameter of the AM process. And utilizing the updated at least one design parameter in the AM process. A system for optimizing the AM process includes a design processor for generating at least one design parameter for an object to be manufactured, and receiving at least one design parameter and uncertainty information, before or during the manufacturing process. It includes an optimization processor for identifying shape errors in the object to be made and updating design parameters based on this shape error.
