The New Obama fuel mileage requirements for cars are music to the ears of the American steel industry. That might seem odd. After all, aren’t a lot of those concept cars rolled out of Detroit every year loaded with plastic and other lightweight materials options? Yes, but a lot of those concepts remain concepts. Take the Chevy Volt for example. It was first shown at the Detroit Auto Show in January 2007 with a polycarbonate roof and a hood made from recycled soda bottles. Once GM decided to actually make the Volt, those two ideas were quickly dropped. Too impractical. Too expensive. A study recently released by the American Iron and Steel Institute predicts a 10 percent annual growth rate in the use of advanced high-strength steels through 2020 as auto makers try to meet tough new fuel standards.
Several of the new and noteworthy 3D printers in this slideshow are breaking some boundaries in build volume, new metals printing techniques, or working with high-profile development partners to ensure very high-quality parts and controls.
United Launch Alliance will fly 3D-printed flight hardeware parts on its rockets starting next year with the Atlas V. The company's Vulcan next-gen launch vehicle will have more than 100 production parts made with 3D printing. The main driver? Parts consolidation and 57% lower production costs.
A new report from the National Institute of Standards and Technology (NIST) makes a start on developing control schemes, process measurements, and modeling and simulation methods for powder bed fusion additive manufacturing.
Although bio-based polymers face challenges from petroleum-based polymers, in certain markets they can displace the petro-based incumbents. Here are six new bio-based and renewable plastics for a variety of applications.
BASF has developed tools and initiatives to help engineers use more of its renewable materials in their designs, more effectively, as well as to build parts using them with more predictable performance.
