... is important to contribute to transitioning L-PBF from a prototyping to a production manufacturing process. Laser powder bed fusion (L-PBF) is an additive manufacturing (AM) process in which a laser selectively melts and fuses metal powder particles in a layer-by-layer fashion to create macroscale parts...

...B. Jalalahmadi; J. Liu; Z. Liu; A. Vechart; N. Weinzapfel Additive manufacturing (AM) processes create material directly into a functional shape. Often the material properties vary with part geometry, orientation, and build layout. Today, trial-and-error methods are used to generate material...

...Peter Renner; Swarn Jha; Yan Chen; Ajinkya Raut; Siddhi G. Mehta; Hong Liang Products made from additive manufacturing processes have attracted great attention in engineering, health care, and society at large. However, there is little knowledge about the failure of additively manufactured alloys...

... morphing surface and its realization using additive manufacturing (AM). By using a diaphragm structure, morphing performance is achieved even if a hard resin material is used. When air pressure is applied to the backside of the diaphragm, it changes to a convex shape and vice versa. The concept requires...

... veins affected the skin friction. Four kinds of polygonal three-dimensional (3D) patterns were designed and fabricated by additive manufacturing technology, and the skin friction coefficients (C f ) of various models were measured by the wind channel experiments. The quantitative effects of models on C...

...Ashish Kumar Mishra; Ram Krishna Upadhyay; Arvind Kumar Additive manufacturing (AM) has witnessed substantial growth in recent years due to its excellent manufacturing capabilities and innovative production methodologies. However, the mechanical suitability aspect in terms of material wear has...

... the development of a special know-how and most importantly, limit the design creativity to what is manufacturable using sheet metal forming. Additive manufacturing (AM) is a disruptive technology in prototyping and fabrication. This paper accesses the feasibility of AM in the fabrication of GFBs using selective...
