IIT Guwahati Researchers Develop 3D Printed Urban Furniture Using Local Industrial Waste

04 February 2022: Researchers from Sustainable Resources for Additive Manufacturing (SReAM), IIT Guwahati, have developed 3D printed urban furniture using local industrial waste. Reseachers have also developed cementitious mix compositions, amenable for 3D printing. The SReAM team comprising, Dhrutiman Dey, Dodda Srinivas and Bhavesh Chaudhari have developed by IIT-G and Deltasys E Forming. This concrete printer comprises of industrial wastes as binders to build 3D printed furniture with a seating height of 0.4 m, a width of 0.4 m, and arch-shaped support that was modelled and sliced using SolidWorks and Simplify 3D. The optimized designs are printed with 75 per cent less concrete and without the need for mold. This entire unit was printed layer by layer at an 80 mm/s speed, with each layer having a 10 mm height. After the unit was printed, it was covered by moist gunny bags for 7 days to cure before being utilized.

Indian Institute of Technology Guwahati was established in 1994. The academic programme of IIT Guwahati commenced in 1995. At present the Institute has eleven departments and five inter-disciplinary academic centres covering all the major engineering, science and humanities disciplines, offering BTech, BDes, MA, MDes, MTech, MSc and PhD programmes.
