Metal 3D printing services: Huirui has been providing customized metal 3D printing services to customers since its establishment. With the company’s many years of production and R&D experience in the field of laser material processing, as well as its knowledge and talent pool in the field of metallurgical materials, it is able to provide Customers provide DED printing services including preliminary equipment modeling, material process package development, part printing and molding, and subsequent heat treatment and machining.
At present, LMD processes for more than 10 metal materials, including stainless steel, aluminum alloys, nickel-based high-temperature alloys, tungsten alloys and ceramic composites, have been developed, including corresponding post-processing processes. Combining multi-axis linkage technology, online detection and feedback control technology, as well as innovative development of processes and core components, we develop customized 3D printing equipment for customers. We can provide customers with multiple types of atmosphere chambers, mobile and workstation types, Integrated development of multi-configuration 3D printing equipment.

Accumulated laser additive process database for various high-performance alloy materials

Laser Metal Additive Manufacturing Direct Layer Technology – Powder-fed 3D printing uses laser as the energy source to generate and move a molten pool in the deposition area. The material is directly fed into the high-temperature melting zone in the form of powder or filamentary material. After melting, it is deposited layer by layer. This metal additive manufacturing process is also called Direct stacking technology for DED laser metal additive manufacturing.

Years of experience in production and R&D in the field of laser material processing
Compared with other metal 3D printing technologies, powder-fed laser 3D printing has the characteristics of high molding efficiency, no limit on printing size in theory, and can realize the mixing of multiple materials and additive manufacturing of functionally graded materials. Through process control, it can have 100% density, a true metallurgical bond between the alloy material and the base material, the strength can be close to the forging level, it is widely used in the field of repair and remanufacturing of metal parts and large-area surface cladding strengthening.
It is particularly suitable for direct molding and hybrid manufacturing of complex parts, such as repair and 3D printing of aerospace engine parts, 3D printing manufacturing of complex aerospace structures, etc.
