PrintRBot is an Open Hardware project in Lincoln, CA by Brook Drumm. Brook claims that the kit is designed to be the simplest 3D printer yet. He says "There are some great kits out there - the Makerbot, the Ultimaker, the Prusa Mendel, and others - but none as small and simple as the Printrbot."
"This all-in-one 3D printer kit can be assembled and printing in a couple of hours. Other kits will not only take you many more hours to build, they will also have hundreds more parts, and they will cost more. My design also does away with the finicky calibration and adjustment from which most 3D printers suffer."
Is this the printer a kid could put together? The company has assembled the electronics, the hotend, and the connectors on all the motors and components... no soldering required!" So what's left to assemble? Why leave the last tasks to the user? What's the attraction of that?
Michael Dell brought PCs to the masses by offering a limited palette of options but shipped a working PC to your home or office having sourced the components from around the world. Who will be the Dell of 3DP?
