Metabolix is moving forward with its plans to produce bioengineered polymers from crops other than corn. The Massachusetts company announced it has completed a field trial of tobacco, genetically engineered to “express” polyhydroxyalkanoate (PHA) biobased polymers. In the Metabloix plan, crops such as switchgrass are bioengineered to create a polymer that grows within the plants’ molecular structure.
Tobacco will not be one of those plants when, and if, the idea goes commercial. “Tobacco was one of the crops they were working with in the lab and they were able to gain field trials,” says a company spokesperson. “They saw it as an opportunity to use it as a test crop to lay the groundwork for planning and permitting activities for field trials in bioengineered, non-food oilseed and biomass crops (such as switchgrass and sugarcane) producing PHA.”
A new compression molding compound material combines the light weight, strength, and rigidity of carbon fibers with the flexibility and lower cost of glass materials in a composite compatible with automotive production.
Plastic bearings are real and millions of them are in use doing heavy-duty jobs we used to think only metals could do. Some of Germany-based igus's bearings are traveling around the world as functional parts in a car to demonstrate what they can do.
Baxter showed off his 2.0-derived moves at ATX West this year. The big red guy still looks pretty much the same, but has some new abilities, mostly due to software. The research robot version is now being used in corporate R&D departments as a design platform.
End-production using 3D printing, including objects made of multiple materials in one pass, is getting closer to reality as we saw on the exhibit floor at the recent Pacific Design & Manufacturing Show.
