One of the hot trends on college campuses right now is a higher level of environmental consciousness in cafeterias, once plagued by wasteful food fights. The Sustainable Endowments Institute says that 42 percent of the schools it surveyed have cut back on use of trays, and in some cases totally eliminated them. One college estimates it has saved 14,000 gallons of water by eliminating use of trays at just one dining hall. Details can be viewed at the College Sustainability Report Card. There has also been a drop in food waste, based on the theory that people toted more when they had a tray. There’s also a trend to use of biodegradable plates and utensils, which can be thrown in a composter with food waste. Gosh, I remember when we first started using fiberglass trays in the 1950s. They were cool. Now they’re not. I also remember when I scoffed at the idea of using composters to get rid of waste. I have one now in my backyard. But I haven’t stooped to using biodegradable plates and utensils-yet.
Major changes are happening in the world of 3D printing and additive manufacturing materials, machines, and software. If the industry -- and the design engineers and OEMs it serves -- are to grow, all three areas must become much more tightly integrated.
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.
