This Grant is a Continuation of N00014-14-1-0687 A Cyber-Enabled Platform for Process Variable vs. Part Quality Relationships in Direct Metal Additive Manufacturing
Abstract
The proposed basic research will address the need for accurate control of the microstructures, and thus mechanical properties, generated during additive manufacturing and the dimensional accuracy and quality control of components produced by Direct Digital Manufacturing for the Navy.The approach of the proposed research is to determine the process variable vs part quality relationships for both e-beam and laser powder bed direct metal AM processes. That information will be used to determine the role of part temperature and the process parameters (beam powers and travel speeds) necessary to maintain a constant melt pool geometry and thus enable the real-time modification of processing parameters to achieve the desired uniformity of microstructure, mechanical properties, and part geometry.
