Have any ideas on how to improve materials engineering for golf carts? They’re a great candidate for a new approach because of skyrocketing accidents. Half of golf cart injuries occur on streets or residential property, and there was a surge in golf cart use when gas prices soared last year. One retiree bought a 20-year-old cart for $300 that can go 20 miles on a 10-hour charge. Twenty-six states allow use of golf carts on local streets. Some states require hazard signs on the back, not unlike the bright signs on the back of Amish buggies. A study by the University of Alabama at Birmingham, said about 1,000 Americans suffer injuries monthly due to golf cart accidents. Male teenagers and people over 80 had the highest injury rates. A study by the Center for Injury Research and Policy at Nationwide Children’s Hospital in Columbus, OH, said annual injury rates for golf carts increased 130 percent in a recent 16-year period.
HP revealed more of its 3D printing plans in a recent webinar. Senior vice president of inkjet and graphics solution business Stephen Nigro spoke about how the technology works and expanded on HP's vision of open collaboration to commercialize its Multi Jet Fusion 3D printing technology for end-production, and open collaboration on new materials. He also said HP will create software to help users decide when to use Multi Jet Fusion versus conventional subtractive manufacturing.
A lightweight electric urban concept car designed by several European companies weighs only 992 lb without its battery. It would have weighed 26.7 lb more if its windows were made of glass instead of the specially coated LEXAN polycarbonate resin from SABIC Innovative Plastics.
Skylar Tibbits' team in MIT's Self-Assembly Lab is now 4D printing self-assembling shapes made of programmable carbon composites and custom wood grain. The composites are being used in a sport car airfoil, and the wood grain is beautiful.
The NanoSteel Company has produced high-hardness ferrous metal matrix composite (MMC) parts using a new nanosteel powder in a one-step 3D-printing process. Parts are 99.9% dense, crack-free, and with wear resistance comparable to M2 tool steels.
