Problems solved by technology

Traditional biomaterial 3D printer nozzles (needles), printing substrates and other parts in contact with biomaterials are made of copper alloy materials. With the development of technology, it is increasingly unable to meet the needs of use.
However, ordinary titanium alloy materials, such as Ti-6Al-4V alloy, can not fully meet the requirements because the alloy contains element V, which is potentially toxic to the human body.
