Bengaluru, often lauded as the technological capital of India, has unveiled the country’s inaugural 3D-printed post office, setting a groundbreaking precedent for efficiency, sustainability, and architectural innovation. Situated in the heart of Cambridge Layout near Ulsoor, this post office stands as a testament to Bengaluru’s inventive spirit. The inauguration, graced by the presence of Ashwini Vaishnaw, the Union Minister for Railways, Communications, Electronics & Information Technology, celebrated the city’s ability to push boundaries.
Spanning an expansive 1,021 square feet, the post office materialized within an astonishingly brief 43 days, a remarkable departure from the conventional construction timeframe of approximately 10 months. The technique employed, known as contour crafting, harnessed advanced materials and a specially engineered robotic arm extruder. This approach facilitated meticulous layering, resulting in a structure that seamlessly blended aesthetics with innovation.
This architectural marvel was brought to fruition through a synergistic partnership between Larsen and Toubro, a prominent construction conglomerate, and the technical expertise of the Indian Institute of Technology (IIT) Madras. Originally projected for completion in the previous year’s September, the project culminated triumphantly in May 2023, with a total cost of Rs 23 lakh.
The decision to embrace 3D printing technology was underpinned by its potential to curtail costs by up to 30% and drastically truncate construction timelines. Departing from traditional methodologies, the layer-by-layer approach ushered in a streamlined and resource-efficient process, yielding substantial economic advantages. This innovation not only minimized construction duration and expenses but also signified a paradigm shift from established building practices.
Heading towards this forward-looking endeavor, the Chief Post Master General of Bengaluru, S Rajendra Kumar, lent his support and expertise, solidifying the city’s commitment to pioneering technological advancement.
