Scalable Path Level Thermal History Simulation of PBF process validated by Melt Pool Images
Xin Liu, Xingchen Liu, Goldy Kumar +1
In this paper we outline the development of a scalable PBF thermal history simulation built on CAPL and based on melt pool physics and dynamics. The new approach inherits linear sc…
Six-sigma Quality Management of Additive Manufacturing
Hui Yang, Prahalad Rao, Timothy Simpson +5
In this paper, we propose to design, develop, and implement the new DMAIC methodology for Six-Sigma quality management of AM. First, we define the specific quality challenges arisi…
A Framework for Simulating the Path-level Residual Stress in the Laser Powder Bed Fusion Process
Xin Liu, Xingchen Liu, Paul Witherell
Laser Powder Bed Fusion (LPBF) additive manufacturing has revolutionized industries with its capability to create intricate and customized components. The LPBF process uses moving…
Automatic Volumetric Segmentation of Additive Manufacturing Defects with 3D U-Net
Vivian Wen Hui Wong, Max Ferguson, Kincho H. Law +2
Segmentation of additive manufacturing (AM) defects in X-ray Computed Tomography (XCT) images is challenging, due to the poor contrast, small sizes and variation in appearance of d…
