Advancing efficiency and reliability in thermal analysis of laser powder-bed fusion

Christian Leinenbach

In laser based powder-bed fusion of metals (PBF-LB/M), parts are fabricated by melting layers of powder using a high-intensity laser beam. During this process, the material is exposed to rapid cooling rates and intense thermal gradients, which are the unde ...
