Look for intense collaborative research efforts over the next 10 years to improve additive manufacturing technologies for use in high-tech aerospace applications. The cost of aerospace components is boosted dramatically due to the amount of material beyond the finished geometry that must be removed during manufacturing-often 90 percent or more, according to Chris English, an engineer with GE Aviation. As a result there is increased interest in the potential to use additive manufacturing technologies that were originally developed for rapid prototyping applications.
One example is a project at the George W. Woodruff School of Mechanical Engineering at the Georgia Institute of Technology. Researchers there are looking at the potential to produce net shape low-density cellular metal structures from layer-based additive manufacturing of metal-oxide ceramic slurry followed by post-processing in a reducing atmosphere. A ceramic suspension would be direct printed in a research investigation. Many issues remain, however, with existing additive manufacturing systems including materials available, poor surface finish, difficulties in removing support systems, and inability to make large parts.
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.
