This video is of a selective laser melting (SLM) process, one technology for additive manufacturing. It shows a clear image of a powder bed in the 3D metal printing process. In addition to CAVILUX HF illumination laser system for high-speed imaging, high magnification with long focal length optics was used to capture the footage. CAVILUX HF totally eliminates the bright plasma light generated and enables the clear observation of what is going on under the plasma illumination.
