22 learned from the Huazhong University of Science and Technology, led by Professor Zhang Haiou of Huazhong University of Science and Technology developed the "casting milling integration" of metal 3D printing technology, made the world's first 3D printing forgings. The results are expected to change the history of the world's metal parts manufacturing. 3D metal printing technology at present is to achieve a green casting, but due to lack of forging technology, can not solve the cracks and deformation defects.

to solve this difficult problem in the world, the Zhang Haiou team after more than and 10 years of research, independently developed the "micro forging composite synchronization device, creative will be made one metal casting, forging technology, the first super Western Micro casting side" the edge of forging technology ", greatly improve the strength and toughness of parts, to ensure that the components of the fatigue life and reliability. Professor

Zhang Haiou introduction, the use of the technology to produce parts, its fine degree than the laser 3D printing increased by 50%. At the same time, the shape and size of the parts and the performance of the organization can control, greatly reduce the product cycle. The technology uses metal wire as raw material, the material utilization rate is above 80%, and the price of silk material is only about 1/10 of the material. In the heat source, the cost is only 1/10 of the imported laser because of the high efficiency and low cost.

it is understood that the "printing technology of metal casting and forging and milling 3D integration" has broad application prospects, will include the design, materials, technology, detection, control, equipment manufacturing and a series of elements of the change, to promote China's traditional industrial transformation.
