Rogers Corporation has added six new, extra-soft materials to its 4790-92 PORON Urethanes family. Available in 12- and 15-lb densities, these new products are up to 90% softer than the previous extra-soft, slow-rebound materials. With their longer recovery times and compression set less than 2%, the materials can serve in gasketing and cushioning applications requiring low closure forces, including handheld electronics. These products are cast directly onto a 0.002-inch polyester film. The materials will retain their properties at constant temperatures of up to 158F and can survive intermittent temperatures of up to 250F (121C). Visit www.rogerscorporation.com for more information.
A make-your-own Star Wars Sith Lightsaber hilt is heftier and better-looking than most others out there, according to its maker, Sean Charlesworth. You can 3D print it from free source files, and there's even a hardware kit available -- not free -- so you can build one just in time for Halloween.
