DMK GT460 Large-Format Industrial Metal 3D Printer
Description
The GT460 Large-Format Industrial Metal 3D Printer is a next-generation powder bed fusion solution designed to meet the needs of manufacturers requiring large build volumes, high-speed output, and multi-laser flexibility. It supports up to 8 high-power lasers (configurable) and offers superior powder handling with bi-directional recoating, delivering efficient and accurate part production.
Its open system supports a wide variety of high-performance metal alloys, making it ideal for industries such as aerospace, automotive, medical, energy, and tooling that demand speed, precision, and process transparency.
SLM optical system
field mirror
The role of the 3D-printed field mirror is to transform curvature into flatness, converting a spherical surface into a flat surface as required by the device.
