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.
HP's industry-changing 3D printing announcement for commercial-scale end-production wasn't the only news of note at RAPID 2016 this week. Here are six more game-changing software and hardware news items, plus some videos explaining HP's technology.
HP has launched its long-heralded Multi Jet Fusion 3D printing technology for commercial-scale end-production, plus an ecosystem to go with it. The package could change the entire industrial market for making end-products with additive manufacturing. At the very least, it will be game-changing.
Nearly all the products in this latest crop of new adhesives target electronic and other components for consumer electronics and automotive assemblies. Some are alternatives to liquid adhesives, others are liquids that cure faster, and several stick well to multiple substrate materials.
Getting different types of spacecraft to Mars may require multiple fuel types. NASA is using 3D printing to try out a rocket engine turbopump design that can handle both liquid methane and liquid hydrogen propellant.
