We finally got a look today at the “production version” of the Chevy Volt in a grand news conference in Detroit (which I saw via the Web). The concept car—shown at the Detroit Auto Show 18 months ago—was a drop-dead beauty with edgy, angular lines. It created the kind of chill I felt when I first saw the Dodge Viper, or even the original Corvette. The production vehicle unveiled yesterday? Well, it looks kind of ordinary. In an effort to make the vehicle as aerodynamic as possible, big swooping lines are the dominant look. There’s a lot more window area. It looks more like a car for a hockey mom than Batman. The black roof that looks like polycarbonate is, however, striking. That type of feature would break ground for a mass-market car. The polycarbonate reduces weight and boosts light that could enter the car’s interior. Materials suppliers, such as Sabic Innovative Plastics, were tight-lipped today. Sabic (as GE Plastics) had provided the PC roof and composite body panels for the concept Volt. Earlier, a GM exec had told Design News in an exclusive interview that innovative materials were still very much in play for the Volt.
Last week, the bill for reforming chemical regulation, the TSCA Modernization Act of 2015, passed the House. If it or a similar bill becomes law, the effects on cost and availability of adhesives and plastics incorporating these substances are not yet clear.
The latest crop of coating and sealant materials and devices has impressive credentials. Many are designed for tough environments with broad operating temperature ranges, and they often cure faster, require fewer process steps, and produce less waste.
A new program has been proposed for testing and certify 3D printing filaments for emissions safety. To engineers who've used 3D printers at home this is a no-brainer. It's from a consumer on Kickstarter, and targets use in homes and schools.
For the last 50 years, the Metal Powder Industries Federation (MPIF) has sponsored an awards competition for creative solutions to designing and fabricating near-net-shape parts using powder metal (PM) technologies. Here are the seven Grand Prize winners of the 2015 contest.
Graphene 3D Lab has added graphene to 3DP PLA filament to strengthen the material and add conductivity to prints made with it. The material can be used to 3D print conductive traces embedded in 3D-printed parts for electronics, as well as capacitive touch sensors.
