One of the best showcases in new plastics technology is the annual competition in automotive plastics held by the Society of Plastics Engineers. This year’s grand prize, announced last night, went to General Motors for backlighting using color-converting plastic in the Tahoe SUV. The patented system for producing custom-colored interior backlighting via LEDs (fed through light distribution pipes) uses fluorescing dyes and proprietary light-scattering additives in translucent resins used to mold buttons, knobs, and backlit plates rather than expensive custom-colored LED bulbs. The change in color control makes backlighting in low-volume, niche colors economically feasible. The system supplier is Delphi Electronics & Safety with material from RTP, BASF, and Bayer MaterialScience. The tool was made by Kno-Mar Tool in Clearwater, FL.
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.
