3D Printing On a Microscopic Scale 34
cylonlover writes "Three-dimensional printers are popping up everywhere these days. Some are small enough to fit in a briefcase and others are large enough to print houses, but scientists at the Vienna University of Technology are going for the microscopic. Earlier this year, the university built a 3D printer that uses lasers to operate on a tiny scale. Now they're refining the technique to enable precise placement of a selected molecule in a three-dimensional material. This process, called '3D-photografting,' can potentially be used to create a 'lab on a chip' or artificially grow living tissue."

Your ARE late to the party. They (Professor Lee Cronin of the University of Glasgow and a team of 45 researchers) had big stories about their work released in July of this year (2012).
But to answer your question: not really. It's called prioritizing potential threats. Getting killed driving to work is first (I drive a tiny, tiny sports car), Getting electrocuted or stabbed while at work (pneumatics and high voltage, baby!) Getting nailed by severe thunderstorms or tornadoes in "tornado alley". Being killed as a "domestic terrorist" (I'm prior military that enjoys my rights). Being killed by 3d printed poisons in a terrorist attack ranks lower down the list than even "frozen piss falling from overhead airliner".
Terrorists are people with a variety of skillsets and levels, just like anyone else. If they have the skills to print toxins, they have the skills to do a whole lot worse. High school kids can make explosives by the trashcan full, a real bio-chemical engineer could easily get creative enough to make highly addictive chemicals that are hypnotics and have embed-able dispensers that release only when they receive encrypted transmissions. Want to control a country? Addict and control the political, financial, religious, and military leaders. Screw messing with the weak sheep. That's simply a non-optimum diversion.
