# New Process Allows 3-D Printing of Microscale Metallic Parts

December 01, 2022

Engineers at Caltech have developed a method for 3-D printing pure and multicomponent metals, at a resolution that is, in some cases, an order of magnitude smaller than previously possible. "We had to develop a new way of doing it, and we couldn't rely on heat to build our structures," says [Max Saccone](https://resnick.caltech.edu/people/max-saccone).
