CMI scientists at Ames Laboratory contributed to this research.

Achievement

Publication of article on functionalizing permanent magnet additive manufacturing systems with a magnetic field source. The field source was modeled, designed, prototyped and tested on an existing table-top commercial 3D printer.

Significance and impact

Demonstrates feasibility of simultaneous alignment and printing of permanent magnets. Designed to work with commercial 3D printers without the need for a separate drive system. Can also be driven independently, if needed.

Details and next steps

Will develop an application to predict degree of alignment. Extending capability to CMI additive manufacturing project. Patent application in preparation.
