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.
Most of the new 3D printers and 3D printing technologies in this crop are breaking some boundaries, whether it's build volume-per-dollar ratios, multimaterials printing techniques, or new materials types.
