<h5>Where is this 3D-printed post office?</h5><p>On 18th August 2023, Ashwini Vaishnaw, Union Minister for Railways, Communications, and Electronics and Information Technology, inaugurated India's first 3D (three-dimensional) printed post office. The post office is located in east Bengaluru. Reports say this is the first commercial building to be built using 3D concrete printing technology in India.</p><p>Larsen and Toubro (L&amp;T) have built this post office. The whole building was constructed in just 43 days (wow!). L&amp;T was helped by the Indian Institute of Technology (IIT) Madras for the building’s structural design.</p><h5>How was 3D printing used to make this building?</h5><div class="raw-html-embed"><figure> <video width="100%" controls=""> <source src="https://firebasestorage.googleapis.com/v0/b/newsahoot.appspot.com/o/india-s-first-3-d-printed-post-office-opened%2F3D%20post%20office.mp4?alt=media&amp;token=b568769f-3493-4a53-bff7-c405af44a0ed" type="video/mp4"> </video> <figcaption>A video of India’s first 3D-printed post office.

A robotic printer was used to deposit the concrete layer by layer as per the design. A special concrete was used that hardened quickly. Building a post office similar to this one takes 6 to 8 months. Its construction time was reduced due to the technology used.</p><p>The construction was also completed for Rs 23 lakh. This is around 30-40% less expensive than typical methods. So, using 3D printing technology to build the post office saved time and money.</p><h5>What is 3D printing?</h5><p><a target="_blank" rel="noopener noreferrer" href="https://www.newsahoot.com/articles/chinese-researchers-make-advancements-in-3-d-printing">3D printing</a> is a cool technology used to make various things. One needs a 3D printer to make the objects. First, one must create a design of the object they want to print (it can be anything like toys, jewellery, etc.). The person can also use an existing design.</p><p>The design is then sent to the 3D printer. The printer then reads the design and starts creating it layer by layer using a material known as filament. It is a type of plastic that the printer softens by heating. This plastic is laid down layer by layer to build the object.</p>

The post office was built in just 43 days.
