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.
The company is privately funded and hopes to accommodate the growing need for housing for those that earn less than $3,000 a year. According to their press release, over 4 billion people live in that income tier and over the next 15 years there will be a need for 100,000 new houses every day.
