The Application of 3D Printing Tantalum Powder in Biomedicine

As a new manufacturing method for global manufacturing industry, additive manufacturing caught the attention of the public six or seven years ago. And “3D printing”, a very down-to-earth and vivid name, was coined. Metal 3D printing is widely regarded as the most promising technology. This year, manufacturers are all aiming for this field, ready. Tantalum powder is an excellent biocompatible material. It has very strong biological inertia and corrosion resistance. Stanford Materials has begun research on the application of 3D printing of tantalum powder in biomedicines such as hip joints.

3D printing

Metalysis has successfully produced a biologically inert tantalum lattice structure, and can have specific and random results. These structures follow the structural rigidity of human bones, and can be well combined with bone cells, so that the human body can excellently accept this kind of new tissue. Stanford Materials is dedicated to providing ultra-fine tantalum powder (D50=3um, D90<10um) for bio-applications. When used for additive manufacturing and selective laser melting, this type of ultra-fine tantalum powder can always maintain structural consistency. The final surface can also be further modified. The metal properties are still very stable.

Tantalum in biology

Tantalum powder has a very wide application in biological field, especially in the field of medicine. Metal 3D printing of hip joints replacement is historic. Matching metal 3D printing replacement organs are made by scanning the hip, allowing patients to have tailored hip joints. This improves the situation where we can only choose from standard sizes in earlier days. In addition to hip joint implants, the supporting lumbar cages of spine are also of particular interest in the industry.
