With the development of the amorphous material industry, the medical industry has increasingly adopted amorphous materials, focusing on innovative medical technology, and turning amorphous metal materials into new medical devices. As part of the Medical Application Clinical Medicine Additive Manufacturing Project (CAMed), the key to this research is to improve the production chain of the entire field. From developing and designing patients’ prostheses or implants, to how to work closely with clinics to manufacture and apply amorphous metal medical products. Because amorphous alloys have extraordinary physical properties, can be integrated into the body and have good compatibility, new 3D printed devices are expected to have a more significant improvement in characteristics than current steel or titanium devices.

Limitations of traditional medical implants

So far, most metal medical implants are made of stainless steel, cobalt-chromium alloy or titanium metal. Although these materials can play a supporting role after being implanted in the human body, they cannot eliminate the interaction force caused by the growth and development of the patient's body tissues. Long-term use of implants with poor elasticity may also cause fatigue fractures. Therefore, the production and application of new medical equipment with excellent ductility, biocompatibility and more ergonomics will bring better medical services to patients. The addition of additive manufacturing technology can make the production process simpler and more detailed.

Why choose amorphous metal materials?

Amorphous metal, also called metallic glass, is a metallic material formed by the rapid freezing of molten metal. Through rapid freezing technology, metal atoms do not form a stable lattice, but are arranged in a disordered manner. This makes the atomic distance of amorphous metal much larger than that of metal crystals, so this material will not have grain boundaries and phase boundaries like ordinary metal materials, and it has special hardness and high elasticity. Not only that, this material also has excellent mechanical properties and has an above-average level of corrosion resistance. At the same time, its biocompatibility is also very good. Indeed, the material has great potential in fields such as aerospace, medical technology, robotics, or electric vehicles.

The manufacturing technology and application of amorphous alloy materials are relatively mature in China, and an industrial chain has been formed. 3D printing technology manufactures amorphous metal products. There are also many domestic research institutions involved in this field. According to the big data information, there are also many domestic 3D printing companies involved in this research.
