Background Information

Using CAD/CAM Computer Aided Design and Manufacturing construction which tended to be the original artisanal profession has been ushered in the 21st century with designs that are totally different from previous generations, costs a fraction of traditionally built houses and minimum time resource waste and environmental impact (Building Radar, 2015). The impact of these technologies are still muted (Occupational Outlook Handbook, 2019) because the technologies are still developing and is currently a novel architectural concept (The Guardian, 2017)

CASE EXAMPLES

Contour Crafting construction projects will be extremely accelerated – for example a 190 m2 house can be constructed in less than 24 hours. This rapid construction time minimizes the financing costs of construction projects that typically take six months or longer to complete.

Apis Cor is a company, which is able to “print” buildings, which are economy and ecology friendly. They developed a mobile construction 3D printer, which is capable of printing whole buildings completely on site. Mobile printer is an efficient operational unit, which can be easily delivered to the site. It requires minimum time and energy to start working in the field. Thus, people can “hire” a printer for work and save on labour costs, dealing with construction waste, renting construction machinery, tools and house finishing. One printer can replace a whole team of construction workers, saving time without loss of quality.

 A Shanghai company, Winsun Decoration Design Engineering Co concluded in 2014 a project to produce 10 houses of 200 square meters each using large 3D printers. When applied this way, 3D printers have the potential to transform the construction industry. Workers that operate these printers require skills in civil engineering and architecture to understand the requirements of the objects to print.
