Researchers measure electron emission to improve understanding of laser-based metal 3D printing

Dec. 2, 2020- 
Lawrence Livermore National Laboratory (LLNL) researchers have taken a promising step in improving the reliability of laser-based metal 3D printing techniques by measuring the emission of electrons from the surface of stainless steel during laser processing. Researchers collected thermionic emission signals from 316L stainless steel under laser powder bed fusion (LPBF) conditions using a...

Lab loans state-of-the-art 3D printer to Cal Poly

June 7, 2017- 
California Polytechnic State University (Cal Poly) San Luis Obispo engineering students now have access to the state-of-the-art in metal additive manufacturing and the ability to perform contracted work for Lawrence Livermore National Laboratory (LLNL), thanks to a new Selective Laser Melting (SLM) machine on loan to the university. LLNL purchased the SLM machine and is loaning it to Cal...
