Autor: Vigneashwara Pandiyan, Rafał Wróbel, Roland Axel Richter, Marc Leparoux, Christian Leinenbach, Sergey Shevchik

Publikováno v: Materials & Design, Vol 235, Iss , Pp 112458- (2023)

This study presents a self-supervised Bayesian Neural Network (BNN) framework using air-borne Acoustic Emission (AE) to identify different Laser Powder Bed Fusion (LPBF) process regimes such as Lack of Fusion, conduction mode, and keyhole without gro
