Bengaluru to get first-of-its-kind 3D printed post office building

I think the problem is not that they used 3D printing, problem india ka ye hai ki uss customer ko literally 20 saal se batana pada ki "pls make a post office for me" I think it would then be called a progress if it were made during that time...sad that such a huge company has so poor management 😢😢 Anyways keep up the progress

We are three brothers: me and my brother who is younger to me by seven years, while 'The Hindu' being elder brother. That sums up the whole bonding, I suppose. We still cherish the hard copies from 2005-06 which are yellowed and diluted, but offer a matchless reading experience.

[@boringgame186]

Normally American homes are made of wood and cardboard, walls are thin enough that 10 year olds can break them easily, it's good for them, in bharat we have 10inch brick walls. It can be used for Affordable housing temporary structures but not for full fledged buildings.

Really interesting.. So does anyone know how it is comparable to traditional building methods in terms of speed and durability?

[@shivakumar-cn9bg]

U can make complicated artistic structures which occupies less space and with same strength which is otherwise which are impossible to construct using manual labour

[@untitled6391]

@@shivakumar-cn9bg not impossible, just more time consuming

[@ankitnmnaik229]

The strength is not as reliable as traditional one..

[@ankitnmnaik229]

would not even briefly consider it, and I used to work with a concrete printer. 3D printed concrete is not traditional concrete. The printing process requires something that can be easily and reliably pumped through a nozzle, but also has gel-like properties so it stays in place once you print it. In order to do this, you don’t really wind up making concrete. You have to remove all the large aggregate (gravel) and then add bentonite clay to get the mixture to gel. It would be more appropriate to call that “mortar” than “concrete” - and the difference is fairly obvious in close-up shots of a printed structure: If you look carefully at that photo, you might notice a couple oddities. For one, the layers are not consistently stacked, and there are lines between each one. 3D-printed concrete is not fully bonded between layers, and there are small air pockets and gaps. No through-holes or anything, but it's not the same as a continuous pour. For another, the color of the concrete seems to change from layer to layer. This is because 3D printing is exposed to the environment, and the material has to be mixed in multiple batches as the building is being printed. This isn’t due to something that can be engineered out, like print volume or machine design constraints, it’s an inherent requirement of the process. By design, the printer must run slower than the material hardens (if it didn’t, the walls would collapse as they got higher). This means the material is inconsistent and poorly-controlled, and is generally much weaker than standard concrete in bulk. Any claims you’ve heard about the strength of 3D-printed concrete are likely false or misleading. It is not currently a reliable process, and because concrete has to stay moist to cure properly, there are all sorts of problems associated with printed structures, like microcracking and extremely poor durability (where the surface is dry and brittle): That’s not to be pessimistic about the capabilities of the tech - these may be the sorts of problems we can fix long-term, and there’s no guarantee it even matters. In fact, we may have fixed it already - some companies have created proprietary concrete blends that may be less sensitive to variability during printing. However, the process of qualification testing for this is not just complex, it involves embracing variability that traditional construction tries hard to remove. This is complicated by the state of the industry - since mix designs have become proprietary to gain a competitive advantage, they all have to be independently tested. I know for certain nothing on the market is qualified currently, because there hasn’t even been enough time to develop testing standards, much less actually do it. Since every new layer is fully exposed at some point during a print, the humidity, cloud cover, wind, temperature, and shape of the building all significantly impact the quality of the final product. Concrete cures on the scale of months, so testing this many variables is absurdly time-consuming. Although the standard for strength measurement is 28 days, that is really a “good enough” threshold, and the large-scale changes we’ve made to the mix design may slow down or speed up that process. There are other complexities beyond this that I could cover, but the basic conclusion here is that this industry has developed so prematurely that we've barely even discussed what the standards should be. The buildings you see in the wild are driven by investors’ Fear of Missing Out and a lack of regulation to stop them. If you buy a 3D-printed house, then you are acting as an early-adopter for a product that's normally intended to last decades, if not centuries. More importantly, the industry is currently speculative enough that if we even tried to impose proper regulatory constraints on it, my guess is most of these companies would go bankrupt doing testing. Perhaps, in several decades, we will have a good understanding of how strong these houses are and how well they age. But we certainly don’t now.

[@Kennethkrishna]

This raises some fundamental questions ! What is cost cutting? How does it help ? How is 3D printing superior to conventional methods of construction? Does it have less carbon footprint ? Does it give job opportunities to construction workers ? Isn’t technology supposed to compliment our development, and not suppress human progress ?

[@kashutosh9132]

All good questions

[@novemberalpha6023]

Good questions.

[@girijaramarao4252]

Answers; Already given as 23 lakhs...saves a plenty of money. 3D priting allows you to construct building as per the site geometry - thick or thin, tall or short, round or square or conical, oblique or flat, etc., etc., Uses same cement, sand , water, electrical energy, ..what is your carbon foot print...?? It reduces man power requirement ...counter ; when does the population control happen ..?? What is human progress is ..?? It's the result of human development & progress that this came into being.

[@Kennethkrishna]

@@girijaramarao4252 1. The price of the raw material is the same. So then, what cost is being cut here?! Money that should go as daily wages to construction workers, instead goes to purchasing Printer and its long term maintenance. How can we justify that? Construction workers are local people with family and children going to school; children are the future pillars of a society 3D printer is a machine (technology )purchased from a developed country.

You can see this in two ways. One that we have achieved a easier and faster way to construct structures. Second is we are massively going to lose out on build quality of houses as this thing is not durable to a point that it cannot even withstand a punch. ( you can read similar stories of how US addapted wood frames to accelerate their build time but ended up with houses that could easily crumble and are not durable.)
