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.
Are you being paid enough? Do you want a better job? According to a recent survey Manpower released just before Engineers Week, employers and engineers don't see eye-to-eye about the state of US engineers' skills and experience.
Two issues have been the bane of the plastics industry for as long as one can remember: The ban on plastic grocery bags and whether the use of bisphenol A (BPA) in plastics such as polycarbonate and PVC is harmful to humans.
One expects to see outlandish apparel at major global fashion events, but New York Fashion Week may have outdone itself, and set a new bar for Paris and Milan, when it put an Ebola jumpsuit in the spotlight.
