...Tesfaye Moges; Kevontrez Jones; Shaw Feng; Paul Witherell; Gaurav Ameta Tremendous efforts have been made to use computational and simulation models of additive manufacturing (AM) processes. The goals of these efforts are to better understand process complexities and to realize better high-quality...

...Piyush Pandita; Sayan Ghosh; Vipul K. Gupta; Andrey Meshkov; Liping Wang Accurate identification and modeling of process maps in additive manufacturing remains a pertinent challenge. To ensure high quality and reliability of the finished product researchers, rely on models that entail the physics...

...Zhimin Xi Laser powder bed fusion (LPBF) process is one of popular additive manufacturing techniques for building metal parts through the layer-by-layer melting and solidification process. To date, there are plenty of successful product prototypes manufactured by the LPBF process. However, the lack...

...Xufeng Huang; Tingli Xie; Zhuo Wang; Lei Chen; Qi Zhou; Zhen Hu Melt pool modeling is critical for model-based uncertainty quantification (UQ) and quality control in metallic additive manufacturing (AM). Finite element (FE) simulation for thermal modeling in metal AM, however, is tedious and time...

...Arunabha Batabyal; Sugrim Sagar; Jian Zhang; Tejesh Dube; Xuehui Yang; Jing Zhang A persistent problem in the selective laser sintering process is to maintain the quality of additively manufactured parts, which can be attributed to the various sources of uncertainty. In this work, a two-particle...
