Peter Mann and Nick McGibbon of Brompton, Ontario are a design and prototyping team with extensive backgrounds in CAD, materials testing, application manufacturing, product design, 3D milling, and 3D printing. They say they've created "the world's first adjustable resolution print head," and it was designed to some very specific problems associated with 3D printing like fixed resolutions and clogged nozzles. The xHead was designed to allow complete cleaning of all of its internal cavities, and the pair say they tested their solution by clogging the entire assembly, including the nozzle, and then letting the filament harden before attempting a repair.
