It was apparent at the recent Great Designs in Steel seminar that steel plans on stealing a page or two from the plastics’ playbook in the key automotive battleground. Steel has several advantages to start with. The manufacturing infrastructure to make steel parts exists, and in fact represents a significant capital investment. Steel also has a strong recycling track record (to say nothing of performance). It seems intuitive that the high gas prices will kick start already existing efforts to reduce weight of cars. But not so fast. New grades of steel reduce weight, and also play into the trend to boost safety performance, particularly for the sides and rear of vehicles. For example an ultra high strength steel (boron-alloyed 22 MnB5) cuts 2 kg for a side crash panel in BMW’s new X6 Sports Activity Coupe. The seven-passenger Acura MDX body structure contains 56 percent high-strength steels, including several new advanced grades. It may surprise some, but some of these new grades are significantly more formable than your father’s steel, allowing creation of complex shapes previously only possible with plastic.
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.
