It has been remarked (and as usual, I can recall neither the exact words nor their putative author) that any sufficiently sophisticated technology is indistinguishable from magic. I have to confess to utter incapacity to figure out how this device can possibly function --- let alone do so cheaper, faster and more accurately than existing devices!

Sounds like you're thinking of Arthur C. Clarke's "3rd Law". Heh, maybe we might even apply all three here. 1. When a distinguished but elderly scientist states that something is possible, he is almost certainly right. When he states that something is impossible, he is very probably wrong. 2. The only way of discovering the limits of the possible is to venture a little way past them into the impossible. 3. Any sufficiently advanced technology is indistinguishable from magic.

The mechanism is very interesting. Ultraviolet images are projected from underneath the tank onto a window to trigger photopolymerization. But the window is oxygen-permeable which inhibits the polymerization in a very thin "dead zone" next to the window. That keeps the solid polymer separated from the window, allowing the solid structure to be drawn up. http://www.sciencemag.org/content/347/6228/1349.abstract On 03/21/2015 10:15 AM, Fred Lunnon wrote:
