3D-printer with nano-precision - Could create or recreate almost anything!! - Peter Lemkin - 23-09-2013
Printing three dimensional objects with incredibly fine details is now possible using "two-photon lithography". With this technology, tiny structures on a nanometer scale can be fabricated. Researchers at the Vienna University of Technology (TU Vienna) have now made a major breakthrough in speeding up this printing technique: The high-precision-3D-printer at TU Vienna is orders of magnitude faster than similar devices (see video). This opens up completely new areas of application, such as in medicine.
The 3D printer uses a liquid resin, which is hardened at precisely the correct spots by a focused laser beam. The focal point of the laser beam is guided through the resin by movable mirrors and leaves behind a polymerized line of solid polymer, just a few hundred nanometers wide. This high resolution enables the creation of intricately structured sculptures as tiny as a grain of sand. "Until now, this technique used to be quite slow", says Professor Jürgen Stampfl from the Institute of Materials Science and Technology at the TU Vienna. "The printing speed used to be measured in millimeters per second our device can do five meters in one second." In two-photon lithography, this is a world record.
This amazing progress was made possible by combining several new ideas. "It was crucial to improve the control mechanism of the mirrors", says Jan Torgersen (TU Vienna). The mirrors are continuously in motion during the printing process. The acceleration and deceleration-periods have to be tuned very precisely to achieve high-resolution results at a record-breaking speed.

...amazing photos...but the possibilities for evil almost outweigh those for good....in the wrong hands. Nano-microphones; nano-webcams; nano-weapons; nano-drones, etc...... On the other hand nano-medicines; nano body replacement parts, nano-computer chips etc......

I'm sure you can find someone to build you nano-gyroscopes to emplace within your brand of golf ball for straight as an arrow flight and compete with nano-dimples for extra distance travel.....science always and only brings good things to life....:

It's been a matter of controversy lately, whether you can 3D print your way to freedom. I want to intervene in this dilemma with some thoughts toward a strategy of 3D liberation.
It's very simple. You start off with the 3D printers becoming mass consumer items, enabling people to print off tat with acrylic or whatever material it is - cheap t-shirts, dresses, trainers, etc. Eventually they become more sophisticated, and you end up printing off pizzas and quarries and libraries. You order the bag of raw ingredients online, and then download the bootlegged 3D design from a file-sharing site or whatever.
But this totally flouts the attempts by the manufacturers to keep income streaming in from their designs. So governments, reacting to business lobby pressure over illegal downloading, cracks down in defence of intellectual property rights. The restrictions implemented are so severe that, suddenly, millions of teenagers can no longer access free dubstep and bestiality videos. They rage in the streets, in ill-fitting, badly printed-off clothes, drinking ill-printed cider.
Meanwhile, about 100 million Chinese manufacturing workers get put out of work, and the heads of CCP bosses roll in the streets while the global economy tanks. Further, the thrusting new petty bourgeoisie in the capitalist core, that was supposed to start a million new enterprises using 3D printers and a fuck load of cash borrowed from banks at usurious interest rates, end up being driven back to the bottom of society, all their stuff repossessed.
The last straw is that people start memes where they print off 3D scans of celebrities in realistic silicone, and take pictures of themselves fisting them in public spaces, with the hashtag: #fistingcelebs. This leads to a strike by all 'creatives' in television and Hollywood.
With no television, no money and no prospects, people are enraged. They draw the logical conclusion that production can no longer be efficiently organised on the basis of private ownership, and as a result we have a global revolution.
That's how we 3D print our way to freedom. True story.

Hope for the best, plan for the worst. Have the gussets of your plus fours let out!
