A German startup called Nanoscribe says it will ship a nanoscale 3D printer in the second quarter of 2013, and that its device will run 100 times faster than similar devices currently in the market:
The technology behind most 3-D microprinters is called two-photon polymerization. It involves focusing tiny, ultrashort pulses from a near-infrared laser on a light-sensitive material. The material polymerizes and solidifies at the focused spots. As the laser beam moves in three dimensions, it creates a 3-D object.
Today’s printers, including Nanoscribe’s present system, keep the laser beam fixed and move the light-sensitive material along three axes using mechanical stages, which slows down printing. To speed up the process, Nanoscribe’s new tool uses a tiny moving mirror to reflect the laser beam at different angles. Thiel says generating multiple light beams with a microlens array could make the process even faster.
The smallest features that can be created using the Nanoscribe printer measure about 30 nanometers, says Julia Greer, professor of materials science at the California Institute of Technology.

Last year, I told you about Individuals Tending Towards Savagery, a terrorist group that has mailed bombs to nanotechnology researchers in Mexico, Chile, France, and Spain. Their stated goal: Stop technological innovation. And they aren't alone.
At Nature News Leigh Phillips reports on a group called the Olga Cell of the Informal Anarchist Federation, which is dedicated to the suppression of science in general and technological innovation in particular. The group is behind several bombings and shootings, mostly targeting nuclear scientists and nuclear energy advocacy groups. Now, the Olga Cell says that it's joining forces with other anti-science terrorist groups around the world. This group is apparently communicating with Individuals Tending Towards Savagery, though it's not clear how close the collaboration is.
On 11 May, the cell sent a four-page letter to the Italian newspaper Corriere della Sera claiming responsibility for the shooting of Roberto Adinolfi, the chief executive of Ansaldo Nucleare, the nuclear-engineering subsidiary of aerospace and defence giant Finmeccanica. Believed by authorities to be genuine, the letter is riddled with anti-science rhetoric. The group targeted Adinolfi because he is a “sorcerer of the atom”, it wrote. “Adinolfi knows well that it is only a matter of time before a European Fukushima kills on our continent.”
“Science in centuries past promised us a golden age, but it is pushing us towards self-destruction and total slavery,” the letter continues. “With this action of ours, we return to you a tiny part of the suffering that you, man of science, are pouring into this world.” The group also threatened to carry out further attacks.
