Abstract

The invention belongs to the technical field of medical application, and discloses additive manufacturing orthopedic tantalum metal, a preparation method and application. A laser melting or electron beam technology is adopted for machining and forming, and production parameters of powder performance, laser melting parameters, equipment stability, powder laying quality, printing precision and oxygen contents are optimized. Hot isostatic pressing (HIP) / heat treatment (HT) is carried out on a formed part, then surface treatment is carried out, and a high-compactness and high-performance formed part can be obtained. The high-compactness and high-performance tantalum metal is provided and has stable and reliable mechanical performance after being implanted into a human body, in-vivo complicated environment and mechanical requirements are met, and different medical application scene requirements can be met in combination with subsequent surface treatment.

Description

technical field [0001] The invention belongs to the technical field of medical application, and in particular relates to additively manufactured orthopedic tantalum metal, a preparation method and application. Background technique [0002] At present, tantalum metal is a medical material with excellent biocompatibility, and also has good corrosion resistance and mechanical properties. Compared with titanium and titanium alloys, which are widely used at present, tantalum metal has better biocompatibility and osteoinductive ability, and is an ideal material for next-generation implants. Additive manufacturing or 3D printing is an emerging manufacturing technology based on digital models that accumulate materials layer by layer. It has significant advantages in combination with medical applications in terms of personalized customization and complex structural parts preparation. In particular, the manufactured porous structure, such as a trabecular-like structure, can promote t...
