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.
The FDA has just released draft guidelines for using 3D printing in the design, development, and manufacture of regulated medical products. Although the recommendations are non-binding, they do set some much-needed parameters.
HP's industry-changing 3D printing announcement for commercial-scale end-production wasn't the only news of note at RAPID 2016 this week. Here are six more game-changing software and hardware news items, plus some videos explaining HP's technology.
HP has launched its long-heralded Multi Jet Fusion 3D printing technology for commercial-scale end-production, plus an ecosystem to go with it. The package could change the entire industrial market for making end-products with additive manufacturing. At the very least, it will be game-changing.
