Laser 3D Printing Enables China to Develop, Produce J-31 Fast, CheapPosted: January 22, 2017
I reported the maiden flight of the new version of J-31 (Gylfalcon) in my post “Maiden Flight of New Improved Version of China’s J-31 Stealth Fighter” on December 24. According to the data provided by its producer, J-31 will be well able to grab a large market share from F-35 as it is much cheaper but comparable with F-35 in functions and performance.
China’s local newspaper Shenyang Daily published a report yesterday why China is able to develop the new version so quickly and make it so cheap as it uses the most advanced 3D printing technology to make the major titanium-alloy part of its structure. The part as shown in the picture on top enables J-31 to carry heavy load.
The technology makes production of J-31 quicker and cheaper compared with the old technology of forging and mechanical processing.
