Refractory materials are metals with melting points exceeding 1650℃. These materials are characterized by their exceptional properties, including high melting points, superior strength at elevated temperatures, and excellent corrosion resistance. They are widely used in military equipment, medical devices, communication technologies and more. The fine spot size and high energy density of green laser ensure high-quality 3D printing of refractory metals such as tungsten, tantalum, molybdenum, zirconium, niobium, and chromium.

The high absorption rate and fine spot size of green laser enable more efficient and precise printing of conventional metals such as high-temperature alloys, titanium alloys, aluminum alloys, stainless steel, and tool steels.
