World's largest delta 3D printer could build entire houses out of mud or clay
WASP (World's Advanced Saving Project) is set to unveil Big Delta, reportedly the world's largest delta 3D printer, later this week. This 12-meter (40 ft) tall behemoth was brought to life with the purpose of building nearly zero-cost housing through the use of local materials and as little energy as possible, offering quick and inexpensive relief to disaster areas and addressing the future housing needs of a rapidly growing world population.
