Ehthanol was once viewed as a way to help solve the climate change problem. Then we heard about the huge amounts of enegy used to make ethanol, anad then the effects of crop prices. It turns out there’s another issue–the impact on plastic used under the hood.
A new fuel tank pressure sensor from Robert Bosch GmbH uses BASF’s Ultramid T KR 4355 G7, a partially aromatic polyamide (PA 6/6T) that fulfills a new and crucial requirement for materials used in electronic housings. Any material that comes into contact with modern fuels has to be able to resist not only gasoline but also water and alcohols such as methanol and ethanol. These substances are found in the tank, especially due to the emergence of flex fuels that contain alcohol. The new polyamide (also called nylon) can withstand the presence of zinc chloride. At the underbody area the sensor may come into contact with this zinc salt that can be formed by splash water.
The FDA has just released draft guidelines for using 3D printing in the design, development, and manufacture of regulated medical products. Although the recommendations are non-binding, they do set some much-needed parameters.
HP's industry-changing 3D printing announcement for commercial-scale end-production wasn't the only news of note at RAPID 2016 this week. Here are six more game-changing software and hardware news items, plus some videos explaining HP's technology.
HP has launched its long-heralded Multi Jet Fusion 3D printing technology for commercial-scale end-production, plus an ecosystem to go with it. The package could change the entire industrial market for making end-products with additive manufacturing. At the very least, it will be game-changing.
