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.
The amount of plastic clogging the ocean continues to grow. Some startling, not-so-good news has come out recently about the roles plastic is playing in the ocean, as well as more heartening news about efforts to collect and reuse it.
Optomec's third America Makes project for metal 3D printing teams the LENS process company with GE Aviation, Lockheed, and other big aerospace names to develop guidelines for repairing high-value flight-critical Air Force components.
A self-propelled robot developed by a team of researchers headed by MIT promises to detect leaks quickly and accurately in gas pipelines, eliminating the likelihood of dangerous explosions. The robot may also be useful in water and petroleum pipe leak detection.
Aerojet Rocketdyne has built and successfully hot-fire tested an entire 3D-printed rocket engine. In other news, NASA's 3D-printed rocket engine injectors survived tests generating a record 20,000 pounds of thrust. Some performed equally well or better than welded parts.
