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.
At this year's MD&M West show, lots of material suppliers are talking about new formulations for wearables and things that stick to the skin, whether it's adhesives, wound dressings, skin patches and other drug delivery devices, or medical electronics.
Researchers at Lawrence Livermore National Laboratory have published two physics-based models for the selective laser melting (SLM) metals additive manufacturing process, so engineers can understand how it works at the powder and scales, and develop better parts with less trial and error.
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.
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.
