Self-Funded Large Concrete 3D printer

Texas engineering student Alex Le Roux, slated to graduate at the end of this year, will be leaving Baylor University with a sense of satisfaction as an innovative maker, designer, and engineer. He has used not only his skills but his own funds to create a concrete 3D printer. With a size of 8' x 8' x 8', the machinery surely fits into Texas standards--and Le Roux hopes to use his invention to 3D print a small house.

Below is a look at Le Roux's concrete 3D printer:

Any way to get a hold of this guy? I would love to ask him a few question's about this type of printing on maybe a little bit of a smaller scale.
