A Brooklyn, NY, researcher has created a plastic made from plants such as corn or soybeans that can be used as a biodiesel fuel. The finding may have particularly significance to the US Army which has been researching new field ration packaging that is lighter, more efficient and contributes less to waste in the field. The new bioplastic is described as stronger than polyethylene and could be used as a vehicle fuel source after rations are consumed. Dr. Richard Gross, director of Polytechnic University’s National Science Foundation (NSF) Center for Biocatalysis and Bioprocessing of Macromolecules (CBBM), made the discovery, and is receiving a $2.34 million award from the Defense Advanced Research Projects Agency (DARPA). Next: Efforts will be made to make the process less costly.
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.
