A Synopsis of 3D Printing and Robotics Applications in Construction

Abstract

One of the difficulties hindering the application of 3D printing technology in construction is related to the versatility of materials and components used to produce a building or other structure. The prospect of using this technology is further complicated by the sheer size of the edifices to be constructed. While 3D printing a mechanical component can now be done in someone's basement with affordable and readily available equipment, applying the same technology to produce large structures and building components is a challenge. In recent years, researchers have been working towards overcoming this challenge by trying to develop new construction materials and methods that would be more suitable for the application of 3D printing technology. One of the approaches that can be considered is the combination of robotics technology with 3D printing to automate construction activities. The use of robots in construction has been proposed long before 3D printing became possible or known but never gained widespread construction site usage, mainly because of the difficulty associated with the automation of most construction tasks. However, the combination of 3D printing with robotics may be the way to change that. In this paper, the authors examine the suitability of 3D printing in a number of construction tasks and present ideas that modify established construction methods to make them more suitable for automation. The authors then examine how the introduction of robotics in conjunction with 3D printing to the construction site may make it possible to automate a number of construction tasks. Some of the benefits of such automation include lower safety risks, improved control over construction schedules, more economical construction, and a better ability to build in remote areas and challenging environments. © Peer-review under responsibility of the scientific committee of the Creative Construction Conference 2019.

Modeling the robotics implementation barriers for construction projects in developing countries

“…While rating benefits of robotics, contractors ranked lowering human labor, cost savings and greater construction stability as the top three benefits of robots, followed by boosting productivity, improving quality, enhancing safety and reducing material waste (Strukov a and L ı ska, 2012). Elhouar et al (2019) regarded prefabricated elements to be the easiest element of construction to automate since they are built in large quantities in a regulated manufacturing setting. Shop-fabricated items, such as structural and timber elements particular to a project that can be managed in a shop setting, are likewise simple to automate.…”

“…In addition, robotics can be used for different construction tasks such as painting, brick overlaying, and earthwork can be performed by robots (Bogue, 2018). In addition, Elhouar et al (2019) discussed the use of robotics during construction and highlighted the potential use of robotics in later phases of the lifecycle.…”

“…The findings of this research can be also applied to other applications such as material delivery, inspection, and site security. The synergies between 3D printing and robotics in construction were discussed by Elhouar et al (2019) who listed the benefits of using 3D printing and robotics to automate various construction tasks, resulting in lowered safety risks, better control of schedule, and reduced cost of construction.…”
