What Is the Powder Bed? | Understanding Laser Powder Bed Fusion

Anyone who has ever looked into the window of a laser powder bed fusion (LPBF) additive manufacturing machine has seen the “powder bed.” It is the flat, continuous field of metal powder through which the laser beam moves to melt the metal and make the 3D printed part. But how does the machine deliver powder and how does it create a fresh powder bed layer for each successive layer of 3D printing? At the Technical University of Denmark (DTU), where researchers have developed an open-source laser powder bed fusion system, Peter Zelinski filmed a series of fundamental videos on the operation of laser powder bed machines — including this video discussing the powder bed, the powder hopper, the recoater blade and how all of them work together.
