Twisted Tower

A new technique developed by Professor Cheng Sun uses light to make 3D printing faster and more precise. In combination with a high-precision robot arm, the method simultaneously provides the freedom to move, rotate, or dilate each layer simultaneously as the structure is being built. Sun’s system introduces the ability to manipulate the original design layer by layer and to pivot the printing direction without recreating the model. This enables the printing of more complicated structures, like this dancing Eiffel Tower, and significantly improves manufacturing flexibility.
