- The first 3D-printed post office in India, located in Bengaluru’s Cambridge Layout, was recently inaugurated.
- Swift 3D Printed Post Office: The 3D-printed post office was built in 43 days, two days faster than the initial deadline.
- Larsen & Toubro Limited completed the project in conjunction with IIT Madras.
Technological Methodology
- The post office has a total space of 1,021 square feet and was built utilising modern 3D concrete printing.
- Robotic printers employed an automated technique to layer concrete in accordance with the authorised design.
- Strong Bonding: The layers were held together by a specially formulated quick-hardening concrete.
- Rapid Construction: Using robotic accuracy and pre-embedded plans, the project was finished in 43 days, significantly less than the standard 6 to 8 months.
The Benefits of 3D Printing
- Cost-Effective: The project cost 23 lakhs, representing a 30-40% cost savings over typical approaches.
- Showcasing Technology: The project demonstrated the scalability of concrete 3D printing technology by utilising indigenous machines and robotics.
Distinctive Characteristics
- Continuous Perimeter: The project’s continuous perimeter structure had no vertical joints.
- Flexibility: 3D printing allowed for curved surfaces and varying site proportions, overcoming the limits of flat walls.
- Structural Innovation: To improve structural integrity, continuous reinforced concrete footings and three-layer walls were built.
- Reduced duration: The unique technique cut the building duration down to 43 days, reducing material waste.
