Announcements of new polymers are infrequent, with most of the action coming in additive systems that enhance performance or processability. DSM Engineering Plastics says it has developed a “breakthrough” polymer called PA4T, a specialized nylon aimed at electronics miniaturization. Specific attributes include excellent dimensional stability, compatibility with lead free soldering, high stiffness and mechanical strength at elevated temperatures, high melting point, and excellent flow and processing window. Potential applications include memory card connectors, CPU sockets, and air/fuel and power train components. A market development plant in the Netherlands will open early next year.
NASA's MAVEN spacecraft has entered Mars' atmosphere, carrying instruments to help Earthlings figure out what happened to it. Launched last November, the spacecraft arrived at the red planet right on time after a journey of 442 million miles.
Airbus Defence and Space has 3D printed titanium brackets for communications satellites. The redesigned, one-piece 3D-printed brackets have better thermal resistance than conventionally manufactured parts, can be produced faster, cost 20% less, and save about 1 kg of weight per satellite.
At IMTS last week, Stratasys introduced two new multi-materials PolyJet 3D printers, plus a new UV-resistant material for its FDM production 3D printers. They can be used in making jigs and fixtures, as well as prototypes and small runs of production parts.
