Titanium is an important structural metal developed in 1950s. Pure titanium is a silvery white metal. It has a bright chemical property and has many excellent properties. Titanium alloys are alloys based on titanium and other elements. Titanium alloy has the characteristics of high strength, good corrosion resistance and high heat resistance. The titanium alloy parts made by 3D printing technology are of high strength and precise size, and their mechanical properties are superior to those of forging technology. Because of its good biocompatibility and excellent mechanical properties, titanium alloys are mainly used for biomedical materials, aerospace, precision instruments and so on.
1. The applications of titanium and titanium alloys in biomedicine
Titanium has been widely used in the field of medicine, becoming the preferred material for artificial joints, bone trauma and orthopaedic spinal fixation system, surgical instruments and other medical products, because the titanium alloy compatibility and corrosion resistance and other characteristics of its good biological. 3D printed embedded titanium alloy material can be personalized design according to individual requirements, for example, the mandible produced by 3D printing can fit perfectly with the patient's affected area curve.
2. The applications of titanium and titanium alloys in aerospace
Since 1950s, titanium alloys have been developed rapidly in the field of Aeronautics and astronautics. The application in aerospace mainly utilizes the excellent mechanical properties, low density and good corrosion resistance of titanium alloys. Titanium alloys are one of the main structural materials of modern aircraft and engines. Besides, aircraft cockpit and ventilation components, aircraft landing gear support, wings and other aircraft components can be produced using 3D printing.
