Model-based definition (MBD) is also used, and it's the third aircraft to utilize MBD technology in the world, after Airbus A380 (2000) and Boeing 787 (2005). The Y-20 is the first cargo aircraft to use 3D printing technology to speed up its development and to lower its manufacturing cost. The 703 Institute achieved another milestone by establishing a comprehensive Chinese evaluation and certification system for aircraft composite materials based on international standards. The performance of the composites is reportedly comparable to those that fulfill FAR Part 25.835. The 703 Institute was created in March 2009 with development taking three years. The Y-20's cabin incorporates flame-retardant composites developed by the 703 Institute of the China Aerospace Science and Technology Corporation (CASC). The composites are produced in China, whereas in the past they had to be imported. The Y-20 uses components made of composite materials.

The official codename of the aircraft is Kunpeng ( Chinese: 鲲 鹏), after the mythical bird that can fly for thousands of miles described in the ancient Chinese Taoist classic Zhuangzi. The project is being developed by Xi'an Aircraft Industrial Corporation and was officially launched in 2006. 'transport-20') is a large military transport aircraft.
