Ten companies have teamed in a $3 million project to commercialize a "pivotal" manufacturing technology. The Laser Engineered Net Shaping (LENS) project uses computer-controlled lasers that, in hours, weld air-blown streams of metallic powders into custom parts and manufacturing molds. The technique is said to produce shapes close enough to the final product to eliminate the need for rough machining. To date, the technology has worked at Sandia National Laboratories. However, the purpose of the Cooperative Research and Development Agreement (CRADA) is to produce an industrial tool that works automatically, robustly, and without constant supervision. In the technique, nozzles direct a stream of metal powder at a central point beneath them. Simultaneously, that point is heated by a high-powered laser beam. The laser and jets remain stationary, while the model and its substrate move to provide continually new targets on which to deposit metal. Dave Keicher, vice president of Optomec, a small Albuquerque, NM, company, plans to produce LENS as a commercial product. firstname.lastname@example.org.
As energy efficiency becomes more and more a concern for makers of electronics devices, researchers are coming up with new ways to harvest energy from sound vibration, footsteps, and even electromagnetic fields in the air.
The government wants to study your brain, and DARPA wants to use similar information to give robots true autonomy beyond any artificial intelligence developed to date. Sound like science fiction? It's not.
A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
