HBDZ Company completed the development of laser melting 3D printing process for spherical tantalum metal powder. Its founder is Yang Jingzhou, a postdoctoral fellow in biomedical engineering at Harvard Medical School.
HBDZ uses Huashu Hi-Tech SLM equipment to print tantalum metal samples with a relative density of 99.3%, a tensile strength of more than 485 MPa, a yield strength of more than 420 MPa, and an elongation after break of more than 18%. The comprehensive mechanical properties are much higher than tantalum metal. Castings, close to forged parts. The porosity of printed porous samples can exceed 85%. Tantalum is a refractory metal with a melting point as high as 2996 ℃. Its 3D printing process is difficult, and it has high requirements on powder performance, laser melting parameters, equipment stability, powder coating quality, and printing accuracy.
Currently reported tantalum metal printed workpieces have a density of less than 95% and a tensile strength of less than 400 MPa. HBDZ is a 3D printing company that masters the technology of tantalum metal SLM printing with high density and high mechanical properties.
Tantalum is widely used in industrial and medical fields. Research and clinical applications have shown that porous tantalum metal has better bone fusion and bone conduction properties than metal titanium and titanium alloys, good bone tissue growth, and excellent bone biofixation. Continent's 3D printed tantalum metal core technology with high density and high mechanical properties will contribute to China's development of high-end orthopedic implants, medical devices and refractory metal industrial components.
On June 1, 2018, Hunan Huashu Hi-Tech and HBDZ established a strategic cooperation in the Science and Technology Park of Perking University, signed a cooperation agreement, and jointly built a "National Engineering Laboratory of Complex Structures for Additive Manufacturing 3D Printing Application Research of Biomedical Materials" center".
HBDZ is a high-tech company co-founded by Harvard University postdoctoral professor Yang Jingzhou and co-founded by overseas returnees. It mainly develops 3D printing new materials, new technologies, new product development and industrialization, and research on human tissue and organ printing. , Providing 3D printing application solutions for industrial fields such as medical health, aerospace, automotive machinery, industrial design and cultural creativity.
This time, Huashu Hi-Tech established a strategic cooperation with Continent Intelligent Manufacturing to jointly build the “National Engineering Laboratory of Biomedical Materials 3D Printing Application Research Center for Additive Manufacturing of Complex Structures” to further promote the industrial development of additive intelligent manufacturing 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 Beijing and even in Hebei Province.
