Built to address the growing housing crisis, the Big Delta 3D printer from WASP uses local materials to build habitable structures on site and with very little energy.
Touted as the world’s largest 3D printer, the Big Delta was inspired by the potter wasp, which builds its home out of layers of mud. The printer stands 40 feet tall, and includes a rotating nozzle/mixer that holds the building material, such as mud or clay. The layers can be laid down relatively quickly, and the system requires only a few watts of power to operate.
The Big Delta is part of the WASP (World's Advanced Saving Project) program, which was founded by Massimo Moretti to use 3D printing to save the world.
