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.
The new composites manufacturing innovation center is intended to be a source of grand challenges for industry, like the kind that got us to the moon under JFK. These aren't the words its new CEO Craig Blue used, but that's the idea and the vision behind the Institute for Advanced Composites Manufacturing Innovation (IACMI).
The 100% solar-powered airplane Solar Impulse 2 is prepping for its upcoming flight, becoming the first plane to fly around the world without using fuel. It's able to do so because of above-average performance by all of the technologies that go into it, especially materials.
As the 3D printing and overall additive manufacturing ecosystem grows, standards and guidelines from standards bodies and government organizations are increasing. Multiple players with multiple needs are also driving the role of 3DP and AM as enabling technologies for distributed manufacturing.
A growing though not-so-obvious role for 3D printing, 4D printing, and overall additive manufacturing is their use in fabricating new materials and enabling new or improved manufacturing and assembly processes. Individual engineers, OEMs, university labs, and others are reinventing the technology to suit their own needs.
For vehicles to meet the 2025 Corporate Average Fuel Economy (CAFE) standards, three things must happen: customers must look beyond the data sheet and engage materials supplier earlier, and new integrated multi-materials are needed to make step-change improvements.
