Developers at Laser Zentrum Hanover (LZH, Germany) are using their two-photon polymerization system to create 100-200 nm structures. The idea is similar to rapid prototyping, but in 3D rather than building with 2D layers. Twin laser beams, generating femtosecond laser pulses focused at the same point in a liquid resin, sweeping through three dimensions, form the nanostructures or microstructures. Two-photon polymerization solidifies the resin at the localized focus area.
The new composites manufacturing innovation center is intended to be a source of grand challenges for industry, like the kind that got us to the moon under JFK. These aren't the words its new CEO Craig Blue used, but that's the idea and the vision behind the Institute for Advanced Composites Manufacturing Innovation (IACMI).
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
