Three advanced plastics welding processes are used in a novel fuel cell based on electroconducting polymer and transition metals in an effort to avoid use of adhesives. “We are using orbital vibration to weld the different membranes (anode and cathode) producing the energy,” comments Didier Perret, sales manager of Branson Ultrasonics in Switzerland. “We are using advanced ultrasonic welding for several assembly operations (to replaces screw, glue or others). And finally we use the latest infrared laser technology GEN 3 to weld the fuel tank with a high safety level.”
These new 3D-printing technologies and printers include some that are truly boundary-breaking: a sophisticated new sub-$10,000, 10-plus materials bioprinter, the first industrial-strength silicone 3D-printing service, and a clever twist on 3D printing and thermoforming for making high-quality realistic models.
Using simulation to guide the drafting process can speed up the design and production of 3D-printed nanostructures, reduce errors, and even make it possible to scale up the structures. Oak Ridge National Laboratory has developed a model that does this.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies.
You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived.
