3D printers let you manufacture any 3-dimensional object out of plastic. You just download the design, fire up the old 3D printer, fill the hopper with plastic, and it’ll slowly print out the object. It sounds cool, and hackers are having a great time playing around with them, but it still doesn’t compare to the scale, quality and cost of traditional manufacturing. It’s still a toy for hackers… right?
As you know, technology has a way of creeping up and then dramatically changing everything. And once you watch this mind-bending video of an ultra-high-resolution 3D printer creating a tiny race car, I think you’ll agree with me that 3D printing technology is improving in leaps and bounds.
Researchers at the Vienna University of Technology recently demonstrated a new kind of 3D printer that can create objects orders of magnitude faster than previous devices, at much finer scales; just a few hundred nanometers wide.
Check out this amazing video of the new 3D printer technology quickly creating a microscopic model of a race car.
Their printer uses a liquid resin which is hardened at exactly the right spots by a focused laser beam (rule 1, everything cool is done with lasers). The lasers can be redirected by mirrors and can harden a line of this liquid resin just a few hundred nanometers wide, giving it a very high resolution.
But it’s also fast. In the past, 3D printers were clocked at millimetres per second. Well, this TU Vienna printer can harden a 5-meter line of resin in 1 second.
There were two discoveries that pushed this advance forward:
What would you use a 3D printer like this for? If it’s this fast and accurate, the mind boggles with the possiblities. The researchers proposed medical applications, like building scaffolding for living cells to attach, allowing you to grow organs in the lab. But the imagination really breaks down trying to imagine the implications for this kind of technology.
Okay, now I want one.
