Newly developed at the Vienna University of Technology, and supremely awesome: Highly tuned mirrors increase the speed and accuracy of 3D printing in nano scale, accomplished through two-photon lithography. But how? Precision lasers are guided through a specialty liquid resin to form the lines and layers that comprise the final object. When the resin simultaneously absorbs two photons, which occurs only at the high intensity center of the laser, the monomers of the resin polymerize and solidify.
Someone get me a walkman and some language learning tapes, I’m going to Vienna!
