Wouldn’t it be great if you did not have to wait for months together for your dream house to be completed? Wouldn’t it be great if you could get it ready in just a blink of an eye? Well, that sure may be too much to ask for, but thanks to the hardworking researchers, you may now get to see an entire building constructed in just one day. That day won’t be far when you walk down to the office on an empty street and notice a couple of buildings around it on your way back home.

It may sound outrageous, but researchers from University of Southern California are of the opinion that just a few years from now that will be possible. All thanks to 3D printing techniques, it will be possible to construct an entire building in as less as one day.

How Will 3D Printing for Construction Help?

Such 3D printing machines can extrude solid concrete walls with interior reinforcement so quickly, that they can finish the shell of approximately 2,000 square feet building in as less as twenty hours. This technology was displayed recently at a conference in San Jose.

This robotic extruding process is known as Contour Crafting. It can be compared to its much smaller 3 dimensional desktop printer equivalent. This method takes all its instructions from CAD software. CAD is used to execute as well as store the architectural designs. The building design can even be customized on the construction site even when the work is going on.

The machines used for this method can even automatically embed the channels for electronics, air conditioning, plumbing, as well as to place electric sensors in the building to monitor its temperature and health. A professor at Viterbi School of Engineering of the same university, Behrokh Khoshnevis is leading this initiative to make the Contour Crafting technology of construction absolutely perfect.

Handling the Concerns

Presently the construction industry is facing a lot of problems and is not in its best of phases. The challenges that have crippled the industry are slow construction, dependence on labor and labor inefficiency. Apart from that, as construction is considered one of the most dangerous and fatal jobs in the world, not many labors are available for it. It kills up to 10,000 people every year and injures an estimated 400,000 people.

New technological innovation in the form of Contour Crafting technology of construction is likely to put an end to this apart from saving a lot of time, money, and resources.
