New polymer systems will be featured players in a bevy of new drug-eluting stents set to enter the market. The stents are placed in blood vessels close to the heart with the intent of releasing drugs that keep arteries open with patients who suffer from arteriosclerosis. It’s become a multi-billion dollar business with a couple of star players, and a spectacular technology display for high tech plastics. One of the exciting new entries features a bioresorbale polymer, first predicted by Design News. This is a plastic that disintegrates within six months, leaving just the cobalt chromium metal stent to prop open the artery. It comes in the Costar system from Conor Medical Systems. Conor was recently acquired by J&J. Abbott is developing a stent that is made of bioresobrale resin, specifically polylactic acid (PLA). It isn’t expected to hit the market for another five years. The new technologies in the stent business were reviewed yesterday at a cardiology meeting called CRT 2007 (Cardiovascular Revascularization Therapies) in Washington DC. My take: It will take a longer for new exciting technologies to make it to the operating table because of lingering questions about the effects of the original drug-eluting polymer stents. The questions focus more on the drugs than the polymers, but this one of the most exciting technology development areas for plastics on the planet.
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.
