Impacts of 3D Printing on the Construction Industry30 Mar 2016 ... Berok Khoshnevis, a researcher at the University of Southern California, is testing a fabrication process called contour crafting. This is a method that could automate the construction of complete structures as well as subcomponents. With contour crafting, Khoshnevis hopes to print an entire building, such as a house, in a single print run. It would include conduits for electrical, plumbing, drywall, and insulation. He thinks it realistic to expect widespread use in the ...

"contour crafting technology has great potential for automating the construction of whole structures as well as sub-components." ... Some disadvantages include: Reduced employee numbers in the industry, since the 3D printer does most of the work; A limited number of materials can be used, since the same printer might not be able to print the required multiple materials; Transportation getting the printers for large in situ components to and from the site; Storage of ...

3D Printing: 8 Major Changes Coming to Construction - Construction ...Lastly, a technique known as contour crafting has been developed that allows large projects, like creating homes, to be done through 3D printing. With the availability to these technologies growing, budding entrepreneurs, business owners and consumers themselves will soon be ... disadvantages of 3D Printing on the Construction Industry. The most noteworthy negative impact 3D printing will have on the construction industry would be the reduction and elimination of existing jobs.

Is 3-D Printing Buildings As Good For The Environment As You Want ...8 May 2014 ... Rather than fabricating individual components for later assembly, Khoshnevis's company contour crafting aims to literally print a building from the ground up. His automated construction technique uses robotic arms and a gantry system to deposit concrete through a nozzle. With continued development, he foresees a spacious dwelling being built in as quick as one day. Khoshnevis is bullish about the ecological benefits of his approach. In a comparative life cycle ...

Next, the 3D printer is used to pour concrete on both sides ... Some of the disadvantages and downsides of 3D printing as a construc

Contour Crafting Process Plan Optimization Part I - Semantic ScholarABSTRACT. contour crafting is an emerging technology that uses robotics to construct free form building structures by repeatedly laying down layers of material such as concrete. The contour crafting technology scales up automated additive fabrication from building small industrial parts to constructing buildings. Tool path planning and optimization for contour crafting benefit the technology by increasing the efficiency of construction especially for complicated structures.
