Laser beams are now the most popular heat source for metal 3D printing. Lasers can direct the heat to specific locations, instantly melting metal materials and satisfying the requirements of melt-pool overlapping and part forming. CO2, YAG, and fiber lasers are the primary laser sources for metal 3D printing, with fiber lasers becoming the mainstream choice due to their high electro-optical conversion efficiency and stable performance.As a manufacturer & supplier of fiber laser chillers, TEYU Chiller offers continuous fiber laser temperature control, covering the 1kW-40kW range and providing cooling solutions for metal 3D printing, metal sheet cutting, metal laser welding, and other laser processing scenarios. Fiber Laser Chiller CWFL-12000 can provide high-efficiency cooling for up to 12000W fiber laser, which is an ideal cooling device for your fiber laser metal 3D printers.
