I still remember how amazed I was when I first saw someone create a 3D-printed wrench, but after seeing what the people at World’s Advanced Saving Project (WASP) are doing with 3D printers, I can’t believe something as laughably small as a wrench ever impressed me. WASP is planning to build a massive 40 foot tall 3D printer known as Big Delta, which the team behind the project claims will be able to 3D print ultra low-cost housing. 

3D printers seem to get bigger and badder with each passing week, but this is just ridiculous. Earlier this week, the 3D printing gurus at WASP (World’s Advanced Saving Project) announced plans to officially unveil a 40 foot tall 3D printer on Friday. Once erected, the massive “Big Delta” will supposedly be the largest 3D printer in the world. While a 3D printer of this size is sure to make even Donald Trump salivate at the prospect of what it can build, the team behind it says the main goal is to use the Big Delta to build extremely low-cost housing. To do this, WASP outfitted the printer to use local materials such as dirt or clay, and built it to function using less than 100 watts of power. With a strong, 20-foot-wide metal body and a printing nozzle which doubles as a materials mixer, WASP’s latest endeavor is an absolute mammoth. Considering these characteristics, Big Delta appears especially valuable in providing quick relief to areas hit by devastating natural disasters.
