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 composite based on a high-performance PEEK-like resin we told you about two years ago when it was still in R&D has now been licensed by the US Naval Research Laboratory (NRL) for commercial manufacturing.
Microsoft, HP, Dassault, and other industry heavyweights in 3D printing have launched a new 3DP file format, 3MF. The consortium says the spec will more fully describe a 3D model and will be interoperable with multiple applications, platforms, services, and printers.
NASA's been working on several different ongoing projects for 3D-printed rocket engine components in metals and now it's reached another first in aerospace 3D printing: a full-scale, 3D-printed rocket engine component made of copper.
