On March 25th and 26th, 2017, the third International Student Competition for Industry 4.0-3D Printer Design was held in Tongji University, Siping Campus. The evaluation committee was comprised of experts from the business community and university professors. 16 delegations from the Beijing Institute of Technology, Chongqing University, Tongji University and other C9 League members participated in the competition covering two projects: speed and precision, and new principles and structure.

The candidates were supposed to complete the given 3-D models by using the machines they designed themselves. Based on criteria such as size precision, weight, appearance and post-processing effect, the judges selected the first, second and third prize for both projects - speed and precision, and new principles and structure. The South China University of Technology won the championship on speed and precision based on their outstanding printing speed. Three teams from Tongji University won the first, second and third prize on speed and precision, respectively.
