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.
Last week, the bill for reforming chemical regulation, the TSCA Modernization Act of 2015, passed the House. If it or a similar bill becomes law, the effects on cost and availability of adhesives and plastics incorporating these substances are not yet clear.
The latest crop of coating and sealant materials and devices has impressive credentials. Many are designed for tough environments with broad operating temperature ranges, and they often cure faster, require fewer process steps, and produce less waste.
A new program has been proposed for testing and certify 3D printing filaments for emissions safety. To engineers who've used 3D printers at home this is a no-brainer. It's from a consumer on Kickstarter, and targets use in homes and schools.
For the last 50 years, the Metal Powder Industries Federation (MPIF) has sponsored an awards competition for creative solutions to designing and fabricating near-net-shape parts using powder metal (PM) technologies. Here are the seven Grand Prize winners of the 2015 contest.
Graphene 3D Lab has added graphene to 3DP PLA filament to strengthen the material and add conductivity to prints made with it. The material can be used to 3D print conductive traces embedded in 3D-printed parts for electronics, as well as capacitive touch sensors.
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.
