Selective laser melting (SLM) is a type of additive manufacturing technique which uses a powder bed to form complex metal parts in a layer-by-layer process. This study aims to understand the material flow of parts manufactured by SLM process using 304L stainless steel powder, which is widely used in numerous applica...

The capabilities of various metal Additive Manufacturing (AM) processes, such as Powder Bed Fusion - Laser (PBF-L) are increasing such that it is becoming ever more common to use them in industrial applications. The ability to print atop a substrate broadens that scope of applications. There is ongoing research regardi...

Valid and accurate models describing the mechanical behavior of additively manufactured cellular materials are crucial to enabling their implementation in critical-to-function parts. Broadly speaking, the modeling approaches commonly used in the literature fall into three categories. Each of these differs in the level ...

Tensile properties of laser sintering grade Polyamide-11 are processed using laser sintering, compression molding, and injection molding and the resultant mechanical properties are reported. The primary contributor to the enhanced mechanical properties of injection molded specimens is a fully healed polymer melt with p...

Additive manufacturing (AM) techniques enable the production of near-net shape parts. Wire-arc direct energy deposition (WA-DED) can achieve a higher deposition rate among other available metal AM methods. Conventional arc welding requires a maximum interpass temperature to limit any reduction in mechanical properties,...
