Advanced molding technologies, such as micro molding and metal injection molding, are under review as a way to lighten the load for U.S. soldiers in combat zones. One potential application: wearable antennas. Options include integrated helmet and fabric antennas. Radiation patterns and gain should be comparable to (or ideally superior to) a whip antenna. No snag hazards are acceptable, breakaway connections may be necessary, and designs that do not require wiring to the helmet are preferred.

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.
Plastic bags can become useful as either raw materials for plastics or feedstock for fuel. It's when they're not recycled that they become a major problem. That's what California's bag ban will prevent.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
