Liu Hongwei, a student at the Chongqing University of Science and Technology, successfully invented a 3D print polishing machine a few days ago.

Compared to current polishing methods, the newly-invented machine is able to complete the polishing procedure in only one minute, significantly saving time and money.

The patent right of the 3D print polishing machine has been transferred at a price of 2 million yuan, helping Liu gain his first bucket of gold. (CQNEWS) (Translated by Liu Kan)
