PBF laser sintering machine LM-M250G

powder bed fusionfiber laserfor non-ferrous metals

Product name
Green-light metal 3D printer LM-M250G

Product description
LM-M250G features a build volume of 256×256×320 mm³ and a 500W green fiber laser designed to improve processing of high-reflectivity materials that absorb poorly in the infrared. The modular design simplifies operation and maintenance. The machine offers a compact layout, intuitive operation and an open control system for extended parameter settings and broader material compatibility.
