Abstract: Metal powder bed fusion additive manufacturing (AM) processes have gained widespread adoption for the ability to produce complex geometries with high performance. However, a multitude of factors still affect the build ...

Abstract: The deformation field, material flow, and mechanics of chip separation in cutting of metals with superimposed lowfrequency modulation (<1000 Hz) are characterized at the mesoscale using highspeed imaging and particle ...

Abstract: Powder bed fusion (PBF) is an additive manufacturing (AM) technology that uses highpower beams to fuse powder material into layers of scanned patterns, thus producing parts with great geometric complexity. For PBF, the ...

Abstract: The quality of additive manufacturing (AM) built parts is highly correlated to the melt pool characteristics. Hence, melt pool monitoring and control can potentially improve the AM part quality. This paper presents a ...
