China Advances 3D Printing for Military Aircraft Components, Enhancing Aerospace Capabilities
China is significantly expanding its use of metal 3D printing in the development of military aircraft. Engineers at the Key Laboratory of Aviation Science and Technology for Novel Aircraft Structures, part of the Aviation Industry Corporation of China’s (AVIC) Shenyang Aircraft Design and Research Institute, have reported breakthroughs in producing large, integrated airframe structures and multifunctional components. This research, conducted by the institute responsible for the J-35 fighter series, focuses on reducing structural weight, simplifying manufacturing processes, and combining multiple functions into individual aircraft components. The laboratory has successfully developed a 16.4-foot integrated structural component designed to bear and transfer loads within an aircraft’s central fuselage, and a 3D-printed annular heat exchanger that integrates heat transfer, air extraction, structural support, and maintenance functions.
