NIST Achieving Better Laser Powder Bed Fusion 3D Printing Melt Pool Control By Implementing Laser Control

Laser powder bed fusion (LPBF) 3D printing uses a focused, high power laser to selectively melt geometric patterns into metal powder and build an almost fully dense, freeform object. The process,…

High-Speed Cameras Used to Monitor 3D Printing Process

3D printing, particulalry laser-powder bed fusion or L-PBF, requires a great deal of monitoring to avoid defects and flaws in the final parts. In a thesis entitled “Process Monitoring for…

Heat Sources Compared for Laser Powder Bed Fusion 3D Printing Simulation
