Engineers still need to make tradeoffs when trying to achieve improved thermal conductivity in plastics. One of the biggest challenges in plastics design today is efficient heat removal from smaller components, some of which operate at higher voltages. Example: LED arrays are becoming more popular in auto headlamps to conserve energy. Research data presented by DuPont at its pre-K 2007 press conference in Prague show three different approaches: 1) Use of high filler content including carbon fiber achieves a high rate of thermal conductivity but is difficult to mold, 2) Boron nitride coated graphite coupled with copper particles coated with glass also work well, but are not cost effective and also have molding issues, and 3) Use of ceramic particles as fillers does not achieve the level of thermal conductivity required by emerging applications.
Some of the biggest self-assembled building blocks and structures made from engineered DNA have been developed by researchers at Harvard's Wyss Institute. The largest, a hexagonal prism, is one-tenth the size of an average bacterium.
Arevo Labs' end-production 3D printing technology for carbon composites includes a high-temperature, filament fusion printer head design and firmware for use with the company's new carbon fiber and nanotube reinforced high-temperature matrix polymers like PEEK.
Stratasys will buy Solid Concepts and Harvest Technologies and combine them with its RedEye service business. The plan takes aim at end-production manufacturing and will create one of the biggest commercial 3D printing and AM service bureaus.
The International Federation of Robotics reports that global sales of industrial robots decreased by 4% in 2012 over 2011. The biggest hit was electrical/electronics manufacturing, down by 13%; but by region, the Amerficas did well.
