Where is the first 3D-printed (Three Dimensional-Printed) post office in India being constructed ?

Correct option is C

The correct answer is: (c) Bengaluru

India’s first 3D-printed post office is being constructed in Bengaluru, Karnataka. The project is being developed at Cambridge Layout near Ulsoor by Larsen & Toubro (L&T) using 3D construction technology, under the technical guidance of IIT Madras. The innovative structure spans 1,021 square feet and was completed in just 43 days, a significant reduction from the 6–8 months required using conventional building methods.

This 3D printing technology works by layering concrete using a robotic arm guided by a computer-controlled design model. The design and construction adhere to building codes and safety standards. The post office will operate under the jurisdiction of India Post and is a pioneering step in modern infrastructure development under government departments.
