@Ann: Many of the comments from your recent article about soy-based polyurethane foam would apply to this material. In fact, corn-based PLA is significantly more objectionable in terms of its impacts on the environment and the global food crisis.
Furthermore, if the goal is to increase the strength, stiffness, and heat deflection temperature of injection molded plastics, it's already possible to do so using traditional mineral fillers such as talc and calcium carbonate.
The mechanical properties of these new PLA blends look roughly equivalent to what could be expected from a talc-filled PC/ABS. The main selling point appears to be the ability to put a USDA "bio-based" label on them.
Of course, the role of the USDA is to expand markets for U.S. agricultural products, which the use of bio-based plastics certainly does.
The company says it anticipates high-definition video for home security and other uses will be the next mature technology integrated into the IoT domain, hence the introduction of its MatrixCam devkit.
Siemens and Georgia Institute of Technology are partnering to address limitations in the current additive manufacturing design-to-production chain in an applied research project as part of the federally backed America Makes program.
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.
