Assessment of the Variability of the Laser Powder Bed Process through In-Process Inspection

Additive Manufacturing by Laser Powder Bed is well-established in several sectors as a manufacturing method of metallic components. However, it has some limitations due to some quality and repeatability concerns for critical applications with high fatigue and damage tolerance requirements. The complexity of the process and its multi-physical nature make it difficult to anticipate the presence of defects and leads to some unexpected defects. Therefore, Oerlikon AM GmbH is assessing in-process monitoring solutions in order to analyze in real-time the process, identify the sources of variability and for the tuning of the Key Process Variables.
