Consider specialty compounds to take advantage of growing interest in molded liquid silicone rubber. Advantages of silicone rubbers include flexibility, thermal stability over a broad temperature range, resistance to solvents, and excellent biocompatibility. Silicones are increasingly being selected by design engineers for valve seats or hoses in autos and aircraft, where their resistance to solvents can be boosted through incorporation of fluorosilicones. Polyurethane is added to improve tear strength for some medical applications. New developments in specialty compounding were reviewed by Mary Krenceski, a research scientist at Extreme Molding in Watervliet, NY at Molding 2008.
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.
