Eastman Chemical is introducing at K 2007 a new material it describes as the most important plastic resin developed in many years. Tritan copolyester uses a new monomer (not identified) to provide a higher glass transition temperature (Tg) than traditional copolyesters. The first grade will target polycarbonate applications in housewares where the new material offers superior chemical resistance and hydrolytic stability. Three commercial applications were announced at the show: Camelbak Products, Petaluma, CA, for a re-usable sports water bottle; VitaMix Corp., Olmstead Falls, OH, for a blender container; and Carlisle Food Service Products,Oklahoma City, OK; for a commercial soup bowl. CamelBak and Vita-Mix specified the new resin in part because it contains no bisphenol-A. Tom Pecorini, senior research associate at Eastman, says the new material has comparable shrinkage rates to PC, requiring no changes to the tooling. Another benefit: Tritan has a lower density than PC, boosting yield. Eastman said it plans to extend the grade slate, but gave no details.
The first photos made with a 3D-printed telescope are here and they're not as fuzzy as you might expect. A team from the University of Sheffield beat NASA to the goal. The photos of the Moon were made with a reflecting telescope that cost the research team £100 to make (about $161 US).
A tiny humanoid robot has safely piloted a small plane all the way from cold start to takeoff, landing and coming to a full stop on the plane's designated runway. Yes, it happened in a pilot training simulation -- but the research team isn't far away from doing it in the real world.
Some in the US have welcomed 3D printing for boosting local economies and bringing some offshored manufacturing back onshore. Meanwhile, China is wielding its power of numbers, and its very different relationships between government, education, and industry, to kickstart a homegrown industry.
