I was starting to type another sentence and accidentally posted it before I was done editing.
There are several companies working on similar technology.
Some of these 3d printed homes can be built for around $10,000 and much cheaper in developing countries.
Some of the stories about the 3d printed homes are mention earthquake resistant, "The company claims that the concrete mixture will last 175 years."
Most of the comments listed here have been covered in several stories from different web sites over several years.

These 3D-Printed Houses Can Be Printed Today and Move-In Ready Tomorrow – for Under $10K
. 3D-printed house in Austin, TX by Icon
Icon has partnered with New Story, a charity dedicated to ending homelessness by providing shelter in distressed and poor communities, to print 800-square-foot houses in under a day for roughly $4,000.How they did it: The Vulcan, a large 3D printer, uses digital blueprints created by engineers to print 34-inch-thick layers of concrete in layered “slices.”
2. Tiny 3D-printed houses by Apis Cor
This round tiny home built by San Francisco-based Apis Cor is only 400 square feet and costs $10,134. The company claims that the concrete mixture will last 175 years.How they did it: A mobile 3D printer on-site erects the house from the foundation up.
3. A neighborhood of 3D-printed houses for rent in Eindhoven, The Netherlands
Eindhoven University of Technology is set to 3D print a neighborhood of concrete houses for rent named Project Milestone. They are most interested in the environmentally friendly potential of 3D printed houses by lowering concrete waste and transportation costs. How they’re doing it: The 3D printer that builds the homes lives on-site and consists of a large robotic arm fitted with a nozzle that squirts out a special cement formulation. The cement follows the architect’s digital blueprint in layers for high strength.
