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.”
The company that brought you 3D-printed eyeglasses has launched both an improved clear polymer material for 3D printing optical components and a high-speed, precision, 3D-printing process for making small- and medium-sized batches in a few days.
We've found an amazing variety of robot hands & arms in medicine, space, and service robots, as well as R&D and assembly. Some are based on industrial designs modified for speed or dexterity, while others more closely emulate human movements, as well as human size and shape.
To give engineers a better idea of the range of resins and polymers available as alternatives to other materials, this Technology Roundup presents several articles on engineering plastics that can do the job.
The first photos made with a 3D-printed telescope are here and they're not as fuzzy as you might expect. A team from the University of Sheffield beat NASA to the goal. The photos of the Moon were made with a reflecting telescope that cost the research team £100 to make (about $161 US).
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. So if you can't attend live, attend at your convenience.
