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.
The promise of the Internet of Things (IoT) is that devices, gadgets, and appliances we use every day will be able to communicate with one another. This potential is not limited to household items or smartphones, but also things we find in our yard and garden, as evidenced by a recent challenge from the element14 design community.
If you didn't realize that PowerPoint presentations are inherently hilarious, you have to see Don McMillan take one apart. McMillan -- aka the Technically Funny Comic -- worked for 10 years as an engineer before he switched to stand-up comedy.
The first Tacoma Narrows Bridge was a Washington State suspension bridge that opened in 1940 and spanned the Tacoma Narrows strait of Puget Sound between Tacoma and the Kitsap Peninsula. It opened to traffic on July 1, 1940, and dramatically collapsed into Puget Sound on November 7, just four months after it opened.
