What price premium will you pay for bioplastics? In general, look for a premium of 20 to 30 percent above what you now pay for a comparable material. That’s an artificial figure, but it’s what OEMs think customers will pay for the environmental friendliness plus the enhanced properties some of these grades will have.I say artificial, because seemingly like all things that overcome our “energy” or “global warming” crisis (pick your decade) costs will be very high until there is economy of scale. And economy of scale for plastics is huge. American OEMs that have been leaders in this field, such as John Deere, have not pursued bio materials for economic reasons. They pursued them for political reasons. Deere, for example, wanted to support its farmer-customers, particularly in the soybean area, where grants were available.
Several of the new and noteworthy 3D printers in this slideshow are breaking some boundaries in build volume, new metals printing techniques, or working with high-profile development partners to ensure very high-quality parts and controls.
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.
A new report from the National Institute of Standards and Technology (NIST) makes a start on developing control schemes, process measurements, and modeling and simulation methods for powder bed fusion additive manufacturing.
Although bio-based polymers face challenges from petroleum-based polymers, in certain markets they can displace the petro-based incumbents. Here are six new bio-based and renewable plastics for a variety of applications.
BASF has developed tools and initiatives to help engineers use more of its renewable materials in their designs, more effectively, as well as to build parts using them with more predictable performance.
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.
