Scientists recreated an ancient Chinese bronze-casting technique with 3D printing; a process that took weeks now takes under 40 hours

Researchers have recreated the logic of an ancient Chinese bronze-casting technique with digital modelling, 3D printing and substitute materials, cutting a process that traditionally takes weeks to less than 40 hours. The study focused on ‘piece-mold casting,’ a distinctive method used to produce ritual bronzes during China’s Shang and Zhou dynasties.
