Key takeaways

India launched its first national-level pilot project for constructing rural houses using 3D Concrete Printing (3DCP) under Pradhan Mantri Awas Yojana-Gramin (PMAY-G) in Andhra Pradesh.
The project targets building 177 houses at a cost of approximately ₹14 crore within six months.
India first 3D-printed single-storey house was unveiled in 2021 by IIT Madras and startup Tvasta on the IIT Madras campus.
The technology uses robotic printers and Building Information Modelling (BIM) to deposit concrete layers without collapsing.

India recently launched its first national-level pilot project for constructing rural houses using 3D Concrete Printing (3DCP) in the state of Andhra Pradesh under the Pradhan Mantri Awas Yojana-Gramin (PMAY-G).

The project aims to build 177 houses at a cost of approximately ₹14 crore.
The government has targeted the complete construction of these houses within a span of six months.

This technology is a form of construction-scale additive manufacturing.
A computer-controlled robotic printer converts digital Building Information Modelling (BIM) designs into physical structures.
The printer creates these structures by depositing specially formulated concrete in successive layers.

The entire process relies heavily on material science and automation.
The concrete mixture must have suitable extrudability, buildability and rapid-setting properties.
These specific properties ensure that successive layers retain their shape without collapsing.

The new technology helps reduce construction time, material waste, labour requirements and dependence on conventional formwork.
These benefits enable faster, cost-effective and standardised affordable housing for citizens.

Beyond rural housing, 3DCP can support disaster-relief shelters, remote-area housing, defence fortifications and rapidly deployable public infrastructure.

Despite its advanced nature, 3DCP still relies on conventional or hybrid construction methods for certain components.
These traditional methods are still needed for foundations, structural reinforcement, roofing, electrical systems and plumbing.

India adoption of construction-scale 3D printing gained momentum in 2021.
In 2021, IIT Madras and startup Tvasta unveiled India first 3D-printed single-storey house on the IIT Madras campus.
Globally, construction-scale 3D printing has moved from experiments to commercial use in regions like the US, China, Europe and West Asia.
Dubai has emerged as a major hub for large-scale construction using 3D printing.
