3D printing has been a hobby of mine (constructing 3D printers as well as printing) and I have an engineering background in high performance ASICs. I would very much like to contribute to the NIH 3D printing exchange. I'm located in RTP NC and a Distinguished Engineer at Cisco Systems. My company strongly encourages volunteerism at this time of need, and I can act as an interface to Cisco's larger engineering community. I'm interested in the challenge of creating efficient HEPA grade masks for critical infrastructure providers.
