IIT Guwahati’s team has developed a 3D printed security post made of M40-grade sustainable concrete that includes industrial waste, fibers, and chemical additives. The post was constructed with the institute’s Infrastructure, Planning, and Management team and is said to be environmentally friendly. The new technology is fully equipped to provide customized homes in India with better quality control and short lead times.
IIT Guwahati has built a 3D printed security post using novel M40-grade sustainable concrete that includes industrial waste, fibers, and chemical additives. The team behind the project, Dodda Srinivas, Dhrutiman Dey, and Akshay Sahu, founded Stratify 3D Pvt. Ltd. under the guidance of Dr. Biranchi Panda, Assistant Professor, IIT Guwahati, and established this digital technology in connection with India’s Prime Minister Narendra Modi’s ‘AatmaNirbhar Bharat’ vision. The 3D security post is fully prepared to offer customized homes in India with better quality control and short lead times.
The 3D printed security post has a carpet area of 85 square feet and 56 modules. The team 3D printed custom-designed tetrahedron modules with overhang attributes of 22 degrees and engraved features up to 40 mm for the first time. To print the overhanging attributes, a special sustainable concrete mix layout (patent pending) was created with distinct accelerator and retarder configurations. The components were printed in 15 hours using an automated concrete 3D printer and then gathered on-site with a special bonding material.
The project addresses the aesthetic potential of digital construction technology while utilizing sustainable construction materials. The security post is environmentally friendly in terms of material and construction composition. The construction industry accounts for 13% of GDP and roughly 40% of overall carbon dioxide (CO2) emissions. Newer technologies like 3D printing are essential for accomplishing a circular construction economy. This necessitates the introduction of novel multi-functional eco-friendly materials obtained from industrial waste.
The 3D printed security post’s on-site arrangement and technology illustration was featured at the Y20 Inception Meet at IIT Guwahati. The post was handed over to security staff to begin operations. The use of sustainable 3D printing technology in construction is advancing rapidly, with other companies, such as CyBe and Mighty Buildings, announcing plans for 3D printed buildings and homes. CyBe’s PPVC system for 3D concrete printing cuts conventional building costs in half, while Mighty Buildings has built the world’s first 3D printed energy-efficient home.
