An interesting design innovation at K 2010 is an electrically conductive plastic compound from A. Schulman being used by a Finnish lighting manufacturer. Copper and tin are loaded at a very high level (60 and 25 percent respectively) in nylon 6. The tin acts like a solder connecting the copper fibers. “The conductivity of the compound is 1,000 times better than the next most conductive plastic compound available (plastic loaded with steel fibers),” says Thilo Stier, innovation manager for A. Schulman. The first production part is a light made by Hella.
The production process for the light is a great story. First, the ABS plate and the PMMA (acrylic) reflector are injection molded in a three-component process. The electrical resistor, diodes, LED and contact pins for the plug are inserted and connected with the new conductive compound, which is called Schulatec TinCo 50. The ABS-coated reflector is then mounted to ensure watertight encapsulation.
Stier says the material is good for housings and lighting applications.
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
