Pune is set to house India’s second post office built using 3D printing technology, with the construction expected to be completed in under three months. Dattatray Varadhi, Assistant Superintendent of Post Office for the Pune Region, shared that the building will be unique, as it will not rely on traditional vertical pillars, bricks, or steel. Instead, a specialized type of cement will be used for 3D printing. The post office will be located in Sahakar Nagar, with the tendering process currently underway, and operations are anticipated to begin next year.

Construction done with 3D printing technology is both economical and ecologically beneficial. Computer programs are used to build 3D shapes, which are then sent as input to the printer. While this type of printing typically uses cement, other materials, such as polymers, have also been researched. The cement is subsequently deposited by the printer's nozzle in accordance with the design parameters and intended shape.

This initiative in Pune follows the successful launch of India’s first 3D-printed post office in Bengaluru, inaugurated by Ashwini Vaishnaw, Minister for Railways, Communications, and IT, last year. The Bengaluru office, completed in just 43 days—two days ahead of schedule—demonstrated the efficiency of 3D printing technology compared to traditional construction methods, which typically take 6-10 months.

Chandigarh (PTI): A low-intensity explosion occurred outside a bar-cum-lounge in the Sector 26 area of Chandigarh early on Tuesday, police said.

The explosion shattered the establishment's glass windows. No casualties were reported, they said.

CCTV camera footage from the area purported to show an unidentified person throwing something towards the bar-cum-lounge and a cloud of smoke then engulfing the place.

The police said they received a call regarding a "loud sound" from the area around 3:30 am. After inspecting the spot, the police team recovered jute rope pieces.

A team from the Central Forensic Science Laboratory collected the samples, the police said and added an investigation was underway.
