Two Maryland residents, DoD employee Nick Lanham and recent University of Maryland engineering school graduate David Edelen, are the co-founders of AaronLouis Technology; after much 3D printing research and three years of design, development, and testing, the two just launched a Kickstarter campaign for their Dark Chip 3D printer series.
