3D Printer Prints House

Researchers are now looking at 3D printing to construct entire buildings using a new fabrication method called Contour Crafting. The concept is similar to other solid free form prototyping techniques only it utilizes a mobile gantry (taller than the building to be constructed) that sets down layer upon layer of concrete. Plumbing, electrical wiring, ductwork and other internal structures can also be added along the way, and an entire house could be erected in as little as 20 hours.

The method is ideal for emergency housing or low cost structures, but will undoubtedly also be used for custom luxury homes. Some even envision it as a way to construct facilities on the moon or Mars.

Benefits of this type of construction include very little waste (including less energy to transport goods), fewer injuries, more efficient buildings, and increased structural strength.
