From the World’s Advanced Saving Project (WASP) comes the largest Delta-style 3D printer in the world, capable of printing homes out of mud.

Delta-style robots are those with three parallel arms, connected at the joint at the base.  In this printer, the joint is the printing mechanism.

This printer, called the BigDelta, is 40 feet tall and prints homes at nearly zero cost.  Inventor, Massimo Moretti, created WASP with the goal to “create a means for affordable fabrication of homes, and provide these means to the locals in poverty stricken areas.”  He saw the need for housing and noted the quality and almost endless supply of dirt/clay/fiber homes.  The machine is capable of producing highly insulated homes that cost next to no environmental footprint.
