Everywhere I explored at Rapid 2009, it was apparent there is a battle under way in materials technology in the fast-emerging rapid manufacturing industry. Some suppliers have “real” materials. Others are stiff and tough. Some are clear. Design engineers can be excused if they can’t keep it straight. You virtually need to keep a daily scorecard. And no matter what you pick, you are probably making some type of tradeoff. There may be some sacrifice in surface finish or accuracy in a laser sintering process. But you get real world metals and plastics that are actually used in functional applications. The range of materials’ qualities you can get with stereolithography systems is impressive. They are increasingly stiff and tough, and will be getting better in terms of thermal properties. Both systems offer the opportunity to create intricate internal shapes, though. And that’s something that’s expensive and difficult to achieve in the injection molding process.
Inspired by the hooks a parasitic worm uses to penetrate its host's intestines, the Karp Lab has invented a flexible adhesive patch covered with microneedles that adheres well to wet, soft tissues, but doesn't cause damage when removed.
Researchers at the Missouri University of Science & Technology have designed a new nanoscale material that can transmit light faster than the 186,000 miles per second it usually takes to travel through air.
It has often been said that as California goes, so goes the nation. This spring, the state's wind power is setting energy generation records and solar energy generation is expected to rise sharply during the second half of 2013.
A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
