In-situ Monitoring of the Laser Powder Bed Fusion Build Process Via Bi-Chromatic Optical Tomography
Procedia CIRP(2022)
Abstract
As metal additive manufacturing (AM) is entering industrial serial production of safety relevant components, the need for reliable process qualification is growing continuously. Especially in strictly regulated industries, such as aviation, the use of AM is strongly dependent on ensuring consistent quality of components. Because of its numerous influencing factors, up to now, the metal AM process is not fully controllable. Today, expensive part qualification processes for each single component are common in industry.
