The future is
here, folks! An amazing video that has gone viral on YouTube showcases
an amazing technology—a 3D printer that replicates tools, and pretty
much anything else you can wrap your head around. The video, a clip from
National Geographic, has racked up a whopping 1.7 million views so far
and is continuing to climb the YouTube charts.
The video features theoretical physicist David Kaplan. Kaplan heads to
Burlington, MA to visit the Z Corporation, developers of an amazing 3D printing technology.
He brings along a crescent wrench to see if they can replicate it with
their 3D printers. Amazingly enough, they can—and the printed wrench
is even functional!
Joe Titlow,
the Vice President of Product Management at Z Corporation, explains how
3D printing works. “Most printers will print things in two dimensions.
A 3-dimensional printer will then take that to the third dimension and
make it something you hold in your hand.” 3D objects are printed using
a specially engineered composite material that starts out as a powder. A
binder material is then added to the powder to bind the object together.
Sounds too
incredible to believe? It’s not. Check it out in action in the video
above. I thought this video was amazing.
