3D printer manufacturer Qingdao Unique has brought three 3D printer models for children's education to the exhibition. One of them looks like a Rubik's cube, one like a giant pencil, and the last one has a modular design that needs to be assembled by children themselves.

"Our company's focus is education," Qingdao Unique sales representative Wang Weiya said. "We tried to make it easy and interesting for schoolchildren to learn and create with our printers."
