Abstract
Official abstract text for this publication.
An aerosol jet printhead comprising an in-line static mixer can mix multiple aerosol streams for co-deposition from a single nozzle. A printhead was designed, fabricated, and tested, demonstrating in-plane functionally graded films. The inline mixing printhead can be used with a compact aerosol jet deposition system.
First claim
Opening claim text (preview).
I claim: 1. A static mixer for a multimaterial aerosol jet printhead, the mixer comprising a plurality of mixing elements contained in a hollow flow tube for mixing two or more ink streams, wherein each ink stream comprises aerosolized droplets of a distinct ink material. 2. The static mixer of claim 1 , wherein the mixer comprises a helix static mixer. 3. The static mixer of claim 1 , wherein the mixer comprises an x-grid static mixer. 4. The static mixer of claim 1 , wherein the two or more ink streams comprise aerosolized droplets of less than 5 microns in diameter. 5. The static mixer of claim 1 , further comprising a mass flow controller for each of the two or more ink streams to control the ratio of the ink streams.
