With the country aggressively pursuing the objective of creating 60 million houses under the Housing for All by 2022 program, this achievement will certainly give a huge fillip for the mass housing segment. L&T has 3D printed a Ground + 1 building of 700 sq. feet built up area at their Kanchipuram facility with a special, in-house developed concrete mix using indigenously available regular construction materials.
The building was printed with both vertical reinforcement bar and horizontal distributors using welded mesh that satisfy provisions in the Indian Codes and optimize the cost of construction. Except for the horizontal slab members, the entire building structure was 3D printed ‘Cast in Situ’ at the job site in an ‘open to sky’ environment within 106 printing hours, using a fully automated 3D printer.
