DAQRI
Well, there aren't too many photos of "behind the scenes," but here's a brief look at what I worked on at DAQRI: (all solid and professional looking shots attributed to DAQRI.)
Primarily what I worked on at DAQRI was finishing and painting hundreds of parts each week. Those parts typically fell into a couple of core categories. Some weeks, we'd have 10 to 20 sets of outer shells and panel inserts, some weeks we'd have hundreds of speaker enclosure pieces, some weeks we'd have all of the above plus more. There were probably about 10 or 15 core parts that showed up week after week. One of our team members would get the files set up in Magics 3d software, we'd clean, fill, and prep the EOS printer, then we'd turn it loose to do its thing. That EOS was an absolute beast of a printer, and produced some incredibly tough and resilient parts.
Outside of printing, priming, and painting, I also got to experiment a bunch with all sorts of silicones, urethanes, foams, clays, etc. I learned a ton about what sort of products were out there, and how best to utilize many different materials while researching potential prototype materials for the different units.
