Consider laser welding for applications using electronic components. Other joining methods can shake embedded components, causing damage. Lasers shine through a transmissive material on top, often natural, into an opaque black material that heats up and melts the natural. The bottom piece often contains carbon black to create opacity that absorbs the laser beam. When two black parts are required, a laser-transmissive black dye is used for the top piece. A new glass-filled nylon compound is designed specifically for laser welding. Luvotech J-3/15/LW BK from Techmer Lehvoss LLC, Clinton, Tenn. is a 15% glass-filled nylon 6. Laser welding requires a pair of materials, one transparent to laser energy and the other laser-absorbing. The first commercial application is a black automotive under-hood part. Techmer is also developing laser-weldable PBT.
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
