The massive 3D printer is termed as “Big Delta” and the makers of this device claim that with 40 foot height and 20 foot in diameter, it is the world’s largest 3D printer. In addition, it is even capable of creating budget friendly clay and mud houses in just one continuous printing session. Despite being so huge, Big Delta uses only 100 watts of power and hence it is extremely energy efficient. It is the behemoth size of Big Delta, which enables the device to print economic houses with ease and speed. WASP team takes its inspiration from the traditional construction methods such as those of clay and mud houses. Big Delta is a beautiful combination of new technologies as well as ancient building techniques and it more or less emphasizes on the use of natural and eco-friendly materials for housing purposes. By creating Big Delta, WASP is promoting eco friendly modes of building houses because it uses materials such as mud, clay, dirt, water and natural fibers to build houses. This helps to lower the cost of the house and also since cement is not used it makes the houses more environment friendly. Last year, a Chinese firm had come up with a method of assembling different parts of the houses which were printed using 3D printers and those houses would have cost around $ 5000. But, it was not like the houses built by Big Delta which are much simpler, quick to build and available at a much lower cost. According to WASP, Big Delta will be able to help the estimated 4 billion people worldwide build their own low cost homes by 2030.
