Tiertime Tech sells tens of thousands of 3D printers to more than 40 countries every year. Its 150-plus staff print products ranging from toys and cartoon figures to mobile phone shells and home decor.
Luo Jun, secretary of the World 3D Printing Technology Industry Alliance, said China needs to step up research and development on the "ink" for 3D printers (that is, material with stable qualities).
"Nickel-based alloy, cobalt chromium alloy and engineering plastics resistant to high temperature and high strength haven't been mass-produced. Some materials used for additive manufacturing are mostly imported items. This could restrict applications of 3D printing," Luo said.
