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.
Materials and assembly methods on exhibit at next week's MD&M West and other co-located shows will include some materials you should see, as well as several new and improved processes. Here's a sampling of what you can expect.
The Food & Drug Administration has approved a 3D-printed, titanium, cranial/craniofacial patient-specific plate implant for use in the US. The implant is 3D printed using Arcam's electron beam melting (EBM) process.
The upcoming MD&M West and co-located shows in Anaheim next month will be host to a huge variety of technologies and special events like the Golden Mousetrap Awards. Here are five reasons for medtech professionals to attend.
Many of the new 3D printers and printing technologies in this slideshow are breaking some boundaries, whether it's build speed, new material types, density and quality of 3D-printed circuit board layers, or build volume in a hybrid printer. We also give some recent market statistics.
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.
