Precision medical "was included in the national key research and development, belongs to the category of" much starker choices-and graver consequences-in planning ", our country medical human bone implantation of not less than 3 million cases each year, tens of thousands of each price to more than 10, early application of the material is stainless steel, nickel chromium alloy, nickel titanium alloy, 2, 3 years recently popular TC4 titanium alloy, the material containing nickel, chromium, or harmful elements such as aluminum, vanadium, and because of its elastic modulus is beyond human bones too much, materials with low affinity, Medical experts and the market are in urgent need of new non-toxic and harmless materials with good human affinity to improve the current situation.
Tantalum - based additive manufacturing technology provides services for medical surgery, dentistry, military, aerospace and other market sectors. The porous tantalum implant made of tantalum metal by 3D printing has better biomechanical compatibility and a elastic modulus close to human bone compared with the common porous titanium implant. In the implantation stability, has a greater advantage. Tantalum metal implants used by 3 d printing spherical tantalum powder, as a result of the tantalum metal melting point 2996 ℃, restricted to the core milling technology. It can break through the limitations of traditional powder making technology, and efficiently prepare high melting point metal powder such as tungsten, molybdenum and tantalum, and at the same time guarantee the extremely high sphericity and low oxygen content of the finished product. This excellent fluidity, filling ability of spherical powder, can adapt to the requirement of metal 3 d printing, in addition to the 3 d printing use micron grade powder, silver, launched the nano, submicron particle size specifications, to provide customized services to other high-end applications, silver, accumulate experience, focus on the high-end market, help the downstream customers to develop new cutting-edge products.
