A Short Review of 3D Printing from Construction Perspective

The construction sector is the largest employer provider in the world and with a high labor demand. Low productivity and few technological advancements have affected the construction sector for a few decades. In recent times, three-dimensional printing an automated method with layer-by-layer control has developed. Over the past decades, three-dimensional printing has changed along with new technology advancements in productive manufacturing. 3D printing has been done for design optimization and to provide changes over traditional production techniques. To compete in a market that is rapidly changing, all industries should adopt new development. The same applies to the construction sector. As a result, the construction sector is paying close attention to 3D printing technology as a new strategic challenge and also adopted it. Reviewing 3D printing is the paper’s primary goal through automation attempts from construction perspective. In several developing countries, prefabricated construction methods have gradually implemented the practice of mixing and pouring concrete on site.
