| |April 20219To optimize the cost of constructing mass housing, it was strategically decided to use regular, locally available construction materials for the mix design to produce at job sites, unlike the present industry practice of buying factory produced pre-packed mortar.Integration of horizontal and vertical reinforcement during the printing process has been another challenge for which certain ingenious methodologies have been devised to embed the reinforcement and suitably modify the print head to accommodate the revised printing methodologies. WHAT ARE THE MAJOR BENEFITS OF THIS TECHNOLOGY?The absence of conventional formwork systems and high design flexibility offered by 3D printing technology gives architects and design engineers the license to `imagineer'. They can for possibilities beyond the constraints of conventional formwork & execution methods. Innovative and fluid construction designs can be explored to enhance aesthetics, improve convenience, and optimize cost. Certainly, fully automated construction will accelerate the pace of construction and ensure high build quality and safety. WHAT ARE YOUR THOUGHTS ON COMMERCIAL VIABILITY OF THE TECHNOLOGY AND FUTURE PROSPECTS FOR THE SAME? With the successful 3D printing of a G+1 building in accordance with the Indian CODAL provisions for such structures, L&T Construction has proved that the organization possesses the requisite expertise to leverage this futuristic technology.However, being a new technology involving a fully automated construction methodology, there are still a few design validation processes to be completed, before taking to market that are being currently addressed through various Indian statutory bodies, research institutions, and the like. Both the 3D printed buildings will be used for such testing and validation. HOW DO YOU SEE THE FUTURE OF 3D PRINTING IN THE SECTOR? 3D concrete printing will completely change the dynamics and offerings of the affordable and mass housing industry. It will usher in a significant upward shift in safety, speed, scale, and superior designs. Architects will begin to play a more defining role to build fluid and building structures that can take aesthetics and convenience to the next level. Made-to-order houses are not too far away! 3D concrete printing will completely change the dynamics and offerings of the affordable and mass housing industry. It will usher in a significant upward shift in safety, speed, scale, and superior designs
