Wasp printing

https://www.youtube.com/watch?v=p_ZbTD-2keo Wasp is an ambitious startup aiming to change the world with 3D printing by providing housing at null cost to the people. Using materials they gather from the ground under their feet, wasp is able to build with less emissions than virtually any other technique and cheaper too, if you're willing to reside in a clay domicile.
