Look for intense collaborative research efforts over the next 10 years to improve additive manufacturing technologies for use in high-tech aerospace applications. The cost of aerospace components is boosted dramatically due to the amount of material beyond the finished geometry that must be removed during manufacturing-often 90 percent or more, according to Chris English, an engineer with GE Aviation. As a result there is increased interest in the potential to use additive manufacturing technologies that were originally developed for rapid prototyping applications.
One example is a project at the George W. Woodruff School of Mechanical Engineering at the Georgia Institute of Technology. Researchers there are looking at the potential to produce net shape low-density cellular metal structures from layer-based additive manufacturing of metal-oxide ceramic slurry followed by post-processing in a reducing atmosphere. A ceramic suspension would be direct printed in a research investigation. Many issues remain, however, with existing additive manufacturing systems including materials available, poor surface finish, difficulties in removing support systems, and inability to make large parts.
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
