3D Printer Could Build a Custom House in 20 Hours
Yahoo News -- "An engineering professor, Behrokh Khoshnevis,
at the University of Southern California, is really thinking big: He
has figured out a way to build housing with a giant 3D printer. The apparatus, instead of being the size of your typical laser printer,
would actually be somewhat bigger than the house it would build through
a concrete layering system called Contour Crafting.
The professor explained the process in a speech at the TEDx conference, which you can watch above.
(Start at 4:30 to see the animation demo.) In the video, the
professor demonstrates how the machine lays down a concrete
foundation, puts up walls, even inserts wiring and plumbing, and
eventually constructs an entire building, which Professor Khoshnevis
says can be completed in less than a day. (All that's left to add are
doors and windows.) Robotics could even be used to add details like
tiles, says the professor."
MP: The 3D printing revolution has just begun. We can expect
hundreds and probably thousands of more examples like this in the
future, as this amazing, innovative, game-changing technology revolutionizes
manufacturing, construction, and our entire world.
