3D printing Technology is growing very fast upto the level of printing a building itself. A professor is working on technology named as Contour Crafting which can print an entire 2,500 sqft house in 20 hours.
Behrokh Khoshnevis is a professor of Industrial & Systems Engineering and is the Director of Manufacturing Engineering Graduate Program at the University of Southern California (USC). He is active in CAD/CAM, robotics and mechatronics related research projects. He was able to make a printhead that can extrude wet cement in such a way that the cement is able to keep its form as each successive layer is printed.
Using the Contour Crafting (CC) developed by Behrokh Khoshnevis , a single house or a colony of houses, each with possibly a different design, may be automatically constructed in a single run, embedded in each house all the conduits for electrical, plumbing and air-conditioning.
The professor believes that his technology would make the construction of efficient buildings so cheap and efficient that we could print houses for Millions of poor people living in slums across the world. And, this kind of building process will avoid the killings and injuries related to construction accidents.
Apart from printing Houses, Contour Crafting can be used for building habitats on other planets. Contour Crafting will most probably be one of the very few feasible approaches for building structures on other planets, such as the Moon and Mars, which are being targeted for human colonization.
3D printing technology is growing in various fields.. Recently a person had created Prosthetic hand using 3D printer.
