Titanium might just be the hottest material on the planet earth right now. Out of England comes news that biochemists at Manchester Metropolitan University believe hospital superbugs could be destroyed simply by applying titanium dioxide nanoparticles to hospital surfaces, and then exposing those surfaces to fluorescent light. Titanium dioxide isn’t exactly a rare material – it’s the most commonly used white pigment. The researchers found that other paint additives, such as calcium carbonate, block the killer properties of titanium dioxide. From Toronto comes word that a company is pitching money and credit card clips made of titanium for people who don’t want to carry wallets. Why titanium? It’s lightweight, hypoallergenic, immune to salt water and extremely durable. Immune to salt water? OK, I don’t get that either. And then there’s Sarah Palin. Those titanium glasses she wears are normally slow sellers – about 9,000 a year globally. Ten days after her selection as John McCain’s running mate, the Japanese manufacturer received 12,000 orders.
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.
