There are no revolutions under way in the world of engineering plastics. New materials today target very specific problems. One interesting set of materials from BASF helps to better insulate houses, as shown in a demonstration project in England. Michael Guibault, a marketing manager for BASF’s construction polymers business in North America, says architects can now design buildings that have the energy-efficiency advantages that previously only came with thicker, traditional materials. Here’s how it works: Plastic capsules are filled with a wax that absorbs and then releases energy by melting and solidifying. When used in an astronaut’s spacesuit, a soldier’s uniform, or within an interior plaster or plasterboard wall, the capsules boost the thermal capacity of the material and reduce temperature swings. "Manufacturers of interior building materials can utilize BASF’s Micronal phase-change microcapsules to create new product categories that can give them a competitive advantage," says Guibault.
This grab-bag of new fasteners and adhesives work with a range of materials they can attach to, as well as a wide variety of applications. Several are for use in consumer applications, such as wearables or other compact electronic assemblies, and some of the adhesives have extended service temperature ranges and cure at room temperature.
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.
