Contour Crafting: A New Building Printing Technology

Recently the 3D printing technology has attracted the construction Industry in few parts of the world; here they have invested in researching this technology for years and come up with 3D printers capable of printing entire houses in a matter of hours. This technology of building houses with the help of 3D printing has been named as ‘Contour Crafting’ by the researchers. Contour Crafting technology has great potential for automating the construction of whole structures as well as sub-components.

Contour crafting is a building printing technology being researched by Behrokh Khoshnevis of the University of Southern California’s Information Sciences Institute that uses a computer-controlled crane or gantry to build edifices rapidly and efficiently with substantially less manual labor. It was originally conceived as a method to construct molds for industrial parts. Researchers are trying to adapt the technology for rapid home construction as a way to rebuild after natural disasters. Utilizing fast setting, concrete like material, contour crafting frames the house’s walls layer by layer until finished off by floors and roofs set up by the crane. The notional idea requires the addition of auxiliary parts, plumbing, wiring, utilities, and significantly consumer devices like audio-visual systems as the layers are built.

There are several advantages of contour crafting such as:

  • Speed of Construction
    • While the conventional building routine requires at least about a month construction of a single house unit excluding painting work, the contour crafting technique boasts of completing a multiple units within 24 hours.
  • Cost of Construction
    • Cost Saving is another major factor worthy of a note. The cost of constructing a single storied house having a built up area of 1000 Sq.ft. by conventional methods is about 2000INR per Sq.ft which amounts to 2000000 INR. But using the Contour crafting technology this can be achieved merely in the range of 6000 USD per unit which amounts to about 360000 INR. To Get TOC, Click Here
