<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 three-dimensional (3D) printed post office. This post office is located in Bengaluru. It was the first time a 3D concrete printing technology was used to make a commercial building in India.</p><p>The company Larsen and Toubro (L&amp;T) built this post office in only 43 days! They got help from 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.

This concrete dried up quickly. Normally, making a post office like this takes a long time. Thanks to this technology, the building was made quickly.</p><p>3D printing the post office also cost less money. So, using 3D printing technology to build the post office saved both 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 way to make stuff. To do it, one needs a 3D printer. First, one must create a design of the object they want to print (such as toys, jewellery, etc.). The person can also use an existing design.</p><p>Next, the design is sent to the 3D printer. The printer reads the design and starts making the thing, one layer at a time. It uses a kind of 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.
