There’s an interesting new player in the plastics-from-plants arena. A company called OriginOil was formed in Los Angeles last year to develop a technology in which plastics and other chemicals are derived from algae. Algae cells contain up to 60 percent oil—who knew? OriginOil developed a helix bioreactor that speeds algae growth. Low-energy lights are arranged in a helix pattern to enhance algae growth. Last month, the company announced automation of the process, providing real-time monitoring, nutrient injection and carbon dioxide delivery at the micron level. Oil is extracted from the cell walls through a microwave process. Believe it or not, there are actually nine companies involved in algae-to-energy development. All the technical issues aren’t resolved, and it will be fa ew years before production units are ready—if then. The economics are a whole different issue. They’re “under study”, says the company. The price of oil, of course, will be a huge factor.
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.
