Atmosphere Effects in Laser Powder Bed Fusion: A Review. [PDF]

Materials (Basel)
The use of components fabricated by laser powder bed fusion (LPBF) requires the development of processing parameters that can produce high-quality material. Manipulating the most commonly identified critical build parameters (e.g., laser power, laser scan speed, and layer thickness) on LPBF equipment can generate acceptable parts for established ...
