Everywhere I explored at Rapid 2009, it was apparent there is a battle under way in materials technology in the fast-emerging rapid manufacturing industry. Some suppliers have “real” materials. Others are stiff and tough. Some are clear. Design engineers can be excused if they can’t keep it straight. You virtually need to keep a daily scorecard. And no matter what you pick, you are probably making some type of tradeoff. There may be some sacrifice in surface finish or accuracy in a laser sintering process. But you get real world metals and plastics that are actually used in functional applications. The range of materials’ qualities you can get with stereolithography systems is impressive. They are increasingly stiff and tough, and will be getting better in terms of thermal properties. Both systems offer the opportunity to create intricate internal shapes, though. And that’s something that’s expensive and difficult to achieve in the injection molding process.
This slideshow includes several versions of multi-materials machines, two different composites processes including one at microscale, and two vastly different metals processes. Potential game-changers down the line include three microscale processes.
UL is partnering with metals additive manufacturing (AM) supplier EOS to provide AM training to EOS's customers. It's designed to promote correct usage of AM technologies by OEMs and others in manufacturing.
To commemorate Earth Day, we take a look at the state of ocean plastic. If things don't change, by 2050 the oceans will contain more plastic than fish by weight. Here are the problems, as well as some solutions.
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.
