"I would like to inquire of the Fullermoney Collective if anyone knows of a publicly traded company, especially on a U.S. exchange, that specializes in cold spray technology? From my VERY limited knowledge of this new hi-tech manufacturing process, it sounds every bit as innovative & exciting as 3D printing."

Eoin Treacy's view Thanks you for bringing this fascinating technology to our attention. Here is a link to the Wikipedia page on the subject. I'm afraid I do not know of any listed companies but Rus Sonic Technology holds a number of patents in the sector.
