BPN985: Multimaterial Nanoscale 3D Printing

We propose a new multimaterial direct-write printing technique with projected sub-micron resolution. Inorganic nanoparticles (≈1-10nm) of common microfabrication materials are electrically charged, manipulated electromagnetically in vacuum with an ion trap, and shot toward a substrate where they deposit onto a part under construction, similar to PVD methods. To date, we have successfully demonstrated basic multimaterial deposition. Eventually, this ion printing technology could allow rapid prototyping of integrated circuits and MEMS.
