With the introduction of polyphenylsulfone (PPSF) for its fused deposition modeling systems, Stratasys Inc. has upped the ante on the mechanical performance available from plastic models created on rapid prototyping machines. This new PPSF offers a tensile strength of 8,000 psi, a flex modulus of 320,000 psi, and a heat-deflection temperature of 189C at 264 psi—all far above the ABS that previously represented the company's highest-performing material. PPSF also exhibits strong resistance to chemicals, including petroleum and chemicals used for medical sterilization. Parker Hannifin served as a beta-test site for the new material and managed to run a PPSF model of a crankcase vapor coalescer on a V8 engine for about 40 hours. Visit www.stratasys.com.
United Launch Alliance will fly 3D-printed flight hardeware parts on its rockets starting next year with the Atlas V. The company's Vulcan next-gen launch vehicle will have more than 100 production parts made with 3D printing. The main driver? Parts consolidation and 57% lower production costs.
The new small-form-factor EZ-BLE PRoC (Programmable Radio on Chip) module is a derivative of the existing PRoC BLE Programmable Radio-on-Chip solution. The EZ-BLE PRoC module integrates the programmability and ARM Cortex-M0 core of the PRoC BLE, two crystals, an onboard chip antenna, a metal shield, and passive components.
The engineers and inventors of the post WWII period turned their attention to advancements in electronics, communication, and entertainment. Breakthrough inventions range from LEGOs and computer gaming to the integrated circuit and Ethernet -- a range of advancements that have little in common except they changed our lives.
