The next generation of North American-built diesel engines, scheduled for introduction during the 2009 to 2011 timeframe, is a bright spot for an otherwise weak powder metal industry. New PM applications include cam gear drives, idler gears, timing system sprockets, and fuel injector gears. Powder-forged connecting rods and PM bearing caps are currently being tested and the outlook is good. General Motors put $69 million into its DMAX diesel engine plant in Moraine, OH to manufacture a new Duramax 6.6-liter V-8 turbo diesel engine that will meet 2010 emissions standards. DMAX Limited is a joint venture between GM and Isuzu Motors Limited and was established as a diesel engine company in 1998. About half of new cars in Europe feature diesel engines, which are more energy efficient than cars with spark ignition systems.
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.
