Considering a move to bioplastics? Consider the experience of John Deere, which is now in the eighth year of a program to use soybean and corn feedstocks that was not originally driven for green reasons. The biomaterials are used in combine panels, backhoe loader hoods, and tractor hoods. Greg McCunnn, who runs the project, says the materials must be cost competitive and must be a performance drop-in for petroleum-based plastics. Needless to say, significant supply chain work was involved, and included funding from the United Soybean Board. Ashland Specialty Chemicals developed polyester resins that include soy and corn feedstocks, while processors Ashley Industrial Molding and Budd (currently Continental Structural Plastics) worked on the molding side. There were also issues related to painting and mold release.
And it amounts to more than a hill of beans: each combine made with the compound uses 1.1 bushels of soybeans and 0.5 bushels of corn.
Some of the biggest self-assembled building blocks and structures made from engineered DNA have been developed by researchers at Harvard's Wyss Institute. The largest, a hexagonal prism, is one-tenth the size of an average bacterium.
Arevo Labs' end-production 3D printing technology for carbon composites includes a high-temperature, filament fusion printer head design and firmware for use with the company's new carbon fiber and nanotube reinforced high-temperature matrix polymers like PEEK.
Stratasys will buy Solid Concepts and Harvest Technologies and combine them with its RedEye service business. The plan takes aim at end-production manufacturing and will create one of the biggest commercial 3D printing and AM service bureaus.
The International Federation of Robotics reports that global sales of industrial robots decreased by 4% in 2012 over 2011. The biggest hit was electrical/electronics manufacturing, down by 13%; but by region, the Amerficas did well.
