As 3D printing slowly creeps from the edges of technology, disruptive enthusiasts, hobbyists with a few grand to spend for tinkering with their AutoCAD doodles and closer to retail center, so do the variety of options an imaginative person has available to use to create and construct. Carbon fiber once was a material exclusive to Formula One racecars, spaceships, luxury goods and other items far from the reach of day-to-day life. Well, for the most part it still is. However, thanks to Boston-based startup MarkForged with the Mark One 3D printer carbon fiber has made its way to 3D printing, making the previous entrants into this emerging field appear as toys for children. The Mark One Carbon Fiber 3D printer has an aluminum frame (unibody of course), follows a design favorable to engineers, uses kinematic couplings to enable precise placement (within 10 microns) and lays claim as the world’s first 3D printer to handle composite materials. Although if you do not need the strength of carbon fiber to construct your Cobra H.I.S.S. tank or Generation 1 Optimus Prime trailer, the Mark One also handles nylon, fiberglass and biodegradable PLA.
