IIT Guwahati Researchers have developed 3D-printed urban furniture from local industrial trash.

People in the building and construction industries are starting to use 3D printing to make concrete. IIT Guwahati and Deltasys E Forming worked together to make a concrete printer. It can make parts up to 1 meter long, 1 meter wide, and 1 meter tall.

Key Highlight:

• Three IIT Guwahati researchers have designed 3D-printed urban furniture utilizing local industrial trash.
• IIT Guwahati researchers Dhrutiman Dey, Dodda Srinivas, and Bhavesh Chaudhari have discovered new 3D printable cementitious mix compositions.
• Developed collaboratively by IIT Guwahati and Deltasys E Forming, the concrete printer can print components up to 1 m long, 1 m wide, and 1 m tall.
• The 3D-printed urban furniture cycle takes roughly 20 minutes.
• The IIT Guwahati research group used 3D-printed furniture with a seating height of o.4 meters, a width of o.4 meters, and arch-shaped support modeled and sliced using SolidWorks and Simplify3D.

Three IIT Guwahati researchers have designed 3D-printed urban furniture utilizing local industrial trash.

It is becoming more used in the building and construction industries. Recently developed 3D-printed modular homes, pedestrian footbridges, business buildings, public schools and low-cost toilet units have the potential to transform the construction industry. The IIT Guwahati research group used 3D-printed furniture with a seating height of o.4 meters, a width of o.4 meters, and arch-shaped support modeled and sliced using SolidWorks and Simplify3D. The entire unit was printed layer by layer at 80 mm/s with a 10 mm layer height. After printing, the unit was covered with damp gunny bags for 7 days to cure.

These constructions were traditionally mold-cast, requiring additional concrete, labor, and formwork preparation. But 3D concrete printing uses less concrete and eliminates the need for a mold. “We showed how material-efficient structures can be generated in our lab-scale 3D printer,” stated Dr. Biranchi Panda of IIT Guwahati’s Mechanical Engineering Department. Our goal is to create high-performance concrete mixtures from industrial wastes for 3D printing.
