RISThermal Modeling and Feedforward Control for Defect Mitigation in Laser Powder Bed Fusion Process
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. Modeling and control of the spatiotemporal temperature distribution (thermal history) in laser powder bed fusion (LPBF) is critical because the thermal history governs defects, such as porosity, poor surface ...
In-Process Monitoring of Part Quality in Laser Powder Bed Fusion Additive Manufacturing Process Using Acoustic Emission Sensors
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this work, we used in situ acoustic emission (AE) sensors for online monitoring of part quality in a laser powder bed fusion (LPBF) additive manufacturing process. Currently, sensors such as thermo-optical imaging cameras ...
