3D Printing Food via Frugal Engineering

Purdue Professor Ajay Malshe challenged his students to design a 3D food printer to deposit almond butter — with stipulations: It needed to be just six to seven parts and completely mechanical. “This teaches frugal engineering, which uses simple principles to achieve the highest goals,” he said.

“It needed to be just six to seven parts, and completely mechanical, with no need for electricity,” said Ajay Malshe , the R. Eugene and Susie E. Goodson Distinguished Professor of Mechanical Engineering. “This teaches frugal engineering, which uses simple principles to achieve the highest goals.”
