On August 28, 2018, the Antarctic bear learned that Hebei Dazhou Zhizao Technology Co., Ltd. recently completed the laser melting 3D printing process development of spherical bismuth metal powder. Hebei Dazhou Zhijian uses Huaying Hi-Tech SLM equipment to print the tantalum metal specimens with a relative density of 99.3%, tensile strength greater than 485MPa, yield strength greater than 420MPa, elongation after fracture greater than 18%, and comprehensive mechanical properties much higher than that of base metals. Castings, close to forged parts. Print porous samples can have a porosity of over 85%. Base metal is a refractory metal with a melting point of up to 2996 ° C. Its 3D printing process is difficult, and it has high requirements on powder performance, laser pointer laser melting parameters, equipment stability, powder coating quality and printing accuracy.
It is currently reported that the base metal printed workpiece has a density of less than 95% and a tensile strength of less than 400 MPa. Dazhou Zhi is a 3D printing company that masters the high-density and high-mechanical properties of base metal SLM printing technology.
Base metals are widely used in industrial and medical fields. Research and clinical applications have shown that porous bismuth metal has better bone fusion and bone conduction properties than titanium and titanium alloys, bone tissue grows well, and bone biofixation is excellent. Dazhou Zhizhi 3D printing high density and high mechanical properties 钽 metal core technology will make a positive contribution to the development of high-end orthopedic implants, medical devices and refractory metal industrial parts in China.
On June 1, 2018, Hunan Huasheng Hi-Tech and Hebei Dazhou Zhishang established strategic cooperation in Baoding University Science Park and signed a cooperation agreement to jointly build a 3D printing application research project for bioengineering materials in the National Engineering Laboratory for Complex Structure Additive Manufacturing. center".
Dazhou Zhizhuang is a high-tech enterprise founded by Dr. Yang Jingzhou, a postdoctoral fellow from Harvard University, and a retired overseas student. He is mainly engaged in research and development and industrialization of new materials, new technologies and new products, as well as human tissue and organ printing research. , providing 3D printing application solutions for industrial fields such as medical health, aerospace, automotive machinery, industrial design and cultural creativity.
The Huaying Hi-Tech and Dazhou Zhishang established strategic cooperation to jointly build a “Development Center for Biomedical Materials 3D Printing Application Research in National Engineering Laboratory for Complex Structure Additive Manufacturing” to further promote the industrialization of Additives in the field of biomedicine. Through strong alliances, we will promote the development of strategic emerging industrial clusters such as additive manufacturing, intelligent manufacturing and new materials in Baoding and even Hebei Province.
