Click that link and watch that video. If it reminded you of The Terminator, you're very observant (or know how to read an article). This is a new method of 3D printing that works completely differently than the currently accepted method of printing several small layers of a solidifying plastic on top of each other to form a 3D Object. This, instead, uses a liquid that solidifies as lasers hit it, and the lasers get constantly redirected and hit the liquid at different angles as the model gets pulled from the liquid.
Let me reiterate: this new method of three dimensional printing involves shooting lasers at things. Let no one tell you otherwise: the future is now, and it's at least slightly cool.
This new method is much faster than the current method too. That Eiffel tower at that level of detail at that size would take at least an hour with current 3d printers. This took under ten minutes, I believe. It's exciting to see the 3D printing industry continue to innovate and improve. Hopefully soon I'll finally be able to download a car, just like that series of ads never wanted me to.
