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.
NASA's MAVEN spacecraft has entered Mars' atmosphere, carrying instruments to help Earthlings figure out what happened to it. Launched last November, the spacecraft arrived at the red planet right on time after a journey of 442 million miles.
Airbus Defence and Space has 3D printed titanium brackets for communications satellites. The redesigned, one-piece 3D-printed brackets have better thermal resistance than conventionally manufactured parts, can be produced faster, cost 20% less, and save about 1 kg of weight per satellite.
At IMTS last week, Stratasys introduced two new multi-materials PolyJet 3D printers, plus a new UV-resistant material for its FDM production 3D printers. They can be used in making jigs and fixtures, as well as prototypes and small runs of production parts.
