Ultrasonic monitoring and machine learning integration for layer-by-layer defect detection in PBF-LB/M

Abstract. The quality of parts produced by PBF-LB/M processes, while promising, is often compromised by defects such as gas pores and lack of fusion. In response to the global push towards closed-loop systems for real-time defect detection and correction, in-situ correction during the PBF process is... View More
