Look for bioplastics such as polylactic acid (PLA) to make a strong run at polystyrene foam packaging in the next three years. The major reason is significant technology development in screw design that brings productivity rates for PLA foaming more in line with polystyrene systems. David Fogarty, president, Plastic Engineering Associates (PEA) of Boca Raton, FL says he has developed new screw designs that have now been licensed to three companies.
Ability to maintain melt temperature is critical because of the low glass transition temperature of PLA. PEA supplies 4.50″ x 6.00″ (120mm x 150mm) and 6.00″ x 8.00″ (150mm x 200mm) sized Turbo-Screws specifically designed for the bioplastic, and has worked in tandem with PLA Supplier NatureWorks. Output rates are said to be in the 75 percent to 85 percent range of polystyrene output.
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.
