Direct digital manufacturing is making fast strides for low-volume applications requiring complex detail, but some significant issues remain. Design engineers require process verification, particularly for high-end parts. For example, the widespread adaption of closed-loop process controls about a dozen years ago provided verification that required process parameters in the injection molding process were being maintained. Direct digital manufacturing systems were originally developed by companies in the rapid prototyping business, where such requirements were not necessary. Parts were simply required for form and fit, and not so much for functional testing. There is often considerable process variation in the new additive fabrication systems being developed for manufacturing directly from digital files. Improvements will come, however, and the new systems are certainly worth a look in several situations, particularly those where there are constant design change orders.
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
