Zip-Tech is a proprietary technology from Dufresne Manufacturing that replaces welding. The ‘zippered’ edges are punched into the part at the turret and are snapped together during the forming process. The process reduces the need for welding, grinding, and even outside finish in some applications by allowing for the joining of pre-plate materials which are otherwise considered hazardous in the welding process. The process can save customers up to 35 per cent on select parts. Zip-Tech is best suited for joining corners, but it can also join different metals. Customers include 3M, CNT and Ciprico.
NASA and Boeing developed a huge, carbon composite cryogenic fuel tank for deep space missions, and started testing it last month. The 18-ft cryotank will enable heavy-lift launch vehicles to send both humans and robots into deep space.
German engineering firm EDAG Group showed a single-piece, 3D-printed car body design inspired by a turtle at the Geneva Motor Show. It came about after an assessment of how additive manufacturing could be applied to making industrial components, modules, and complete vehicle bodies.
