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.
Some of our culture's most enduring robots appeared in the 80s. The Aliens series produced another evil android, and we saw light robot fare in the form of Short Circuit. Two of the great robots of all time also showed up: The Terminator and RoboCop.
Optomec's third America Makes project for metal 3D printing teams the LENS process company with GE Aviation, Lockheed, and other big aerospace names to develop guidelines for repairing high-value flight-critical Air Force components.
This Gadget Freak review looks at a cooler that is essentially a party on wheels with a built-in blender, Bluetooth speaker, and USB charger. We also look at a sustainable, rotating wireless smartphone charger.
