The M160G is a metal 3D printer designed for pure copper and copper alloys, with a build volume of 160×160×200mm. Equipped with the first domestically developed 532nm single-mode continuous green fiber laser, available in 500W and 700W power options, it efficiently addresses the low absorption rate of high-reflective materials for infrared light and improves printing results. The machine features a simple design and easy operation. Its open-source system allows for extensive parameter settings and compatibility with more printing materials.
