Application of additive manufacturing technology of titanium alloy in aerospace field

Additive manufacturing technology first began to be applied in the United States in 2001 carrier-borne fighter aircraft, through titanium alloy additive manufacturing technology to produce aircraft bearing structural parts and applied to aviation production. In 2011, the University of Southampton in the United Kingdom used additive manufacturing technology to produce the overall frame including the wings of the drone, the control panel and the hatch. After 2012, the application of titanium alloy additive manufacturing technology in the field of aviation has achieved unprecedented development, titanium alloy parts are not only widely used in aircraft manufacturing, but also new titanium alloy materials began to be applied in space equipment such as rockets and space shuttles. The parts produced by titanium alloy additive manufacturing technology greatly reduce the number of welds between space equipment. Due to the higher strength of titanium alloy, the safety of space equipment is greatly improved. China's relevant departments and scientific research institutions have also continued to research titanium alloy additive manufacturing technology, and it has now been applied in the aviation field. The aircraft wings and main bearing components produced by titanium alloy additive manufacturing technology in China have reached the corresponding technical requirements and have been applied to aircraft manufacturing. In 2013, Beijing University of Aeronautics and Astronautics produced titanium alloy aircraft main bearing components through titanium alloy additive manufacturing technology, which passed the technical verification and installation review, which makes China the first country in the world to master the design and manufacture of titanium alloy aircraft main bearing components, marking China's titanium alloy additive manufacturing technology into the world's leading position.
