    What is Direct Metal Laser Sintering (DMLS) And How Does It Work?

    April 20, 2022

    DMLS is a powder-bed fusion system utilizing the laser power as the heat source to melt a layer of evenly distributed metal powder. The laser is directed by a mirror to selectively scan over a path defined by the CAD file. The powder layer thickness can be adjusted and usually is set as 30, 60 or 90 microns. Once a layer is finished, the roller dispenses a fresh layer of powder and this cycle repeats until the part is fully printed.
