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 relating to uncertainty in at least one other parameter of the AM process, Performing an uncertainty quantification in the optimization processor based on the at least one design parameter and the uncertainty information to identify a shape error in the object being generated, updating at least one design parameter of the AM process. And utilizing at least one design parameter updated in the AM process. A system for optimizing an AM process includes a design processor for generating at least one design parameter for an object to be manufactured, and at least one design parameter and uncertainty information, prior to or during the manufacturing process. An optimization processor for identifying shape errors in the object to be made and for updating design parameters based on the shape errors.
