Metal 3D Printing to Create Strong, Lightweight Structures for Advanced Laser Systems

LLNL 3DLaser

Ibo Matthews inspects an in situ diagnostics test bench his team developed for studying laser-driven powder bed fusion additive manufacturing. High-speed thermal and optical mapping of the laser-powder interaction has enabled the team to reveal new physics associated with the process and helped guide high-performance computing simulations.

The powder bed laser-melting printer was made by the Fraunhofer Institute for Laser Technology and German startup Aconity 3D. Lab engineers added diagnostics and high-speed cameras to examine thermal emissions and to image the surface of parts as they're being built. Modifications help researchers determine defects or deformations during the 3D printing process.
