New Process Allows 3-D Printing of Nanoscale Metal Structures

13.02.2018 | Caltech | www.caltech.edu

For the first time, it is possible to create complex nanoscale metal structures using 3-D printing, thanks to a new technique developed at Caltech.

The process, once scaled up, could be used in a wide variety of applications, from building tiny medical implants to creating 3-D logic circuits on computer chips to engineering ultralightweight aircraft components. It also opens the door to the creation of a new class of materials with unusual properties that are based on their internal structure.

3-D printing in nanoscale

The way 3-D printing works at the nanoscale is that a high-precision laser zaps the liquid in specific locations of the material with just two photons, or particles of light. This provides enough energy to harden liquid polymers into solids, but not enough to fuse metal.
