The first 3D post office in India will soon be built in Bengaluru utilizing 3D printing technology. Larsen & Toubro is carrying out the project at Cambridge Layout in Ulsoor and has experience developing 3D-printed structures.

with the Cambridge Layout neighborhood of Bengaluru, a work site that is covered with tarpaulins is next to a hospital.

Inside, six workers are huddled in a corner as a robotic arm prints India’s first post office out of concrete in three dimensions.

The 1,100 square foot building is being developed by Larsen & Toubro and would cost Rs 23 lakh to 3D print over 45 days.

The railway minister’s tweet on the technology drew the attention of Prime Minister Narendra Modi, who shared it and wrote: “Good to see new avenues of technology being harnessed for this purpose.”

Around two years ago on the campus of the Indian Institute of Technology (IIT) Madras, Tvasta Manufacturing Solutions built India’s first 3D-printed house, which was dedicated by Finance Minister Nirmala Sitharaman.

She proposed employing technology during the event to promote affordable housing in India, particularly as part of the Pradhan Mantri Awas Yojana (PMAY).

What Expert Say about 3D Concrete printing

According to Experts claim concrete 3D printing can speed up building by up to 30%, cost will remain an issue until the technology is more widely used.

According to experts, a 1,100–1,500 square foot project would take 3–4 months to complete using traditional building methods. They also said that although the price would vary based on a number of factors, it would be slightly more expensive for traditional building techniques owing to greater labor expenditures. ​

What is 3D concrete printing?

Unlike conventional building techniques, 3D printing employs a robotic arm to build layers of a unique concrete mixture that is fed into the machine. Special adhesives in the combination are used for rapid drying and other purposes.

The two primary types of systems are robotic arms and gantry-based ones, in which the printer may be moved horizontally thanks to enormous cranes. The mixture is funneled out of the robotic arm in accordance with the design plans provided into the system.

One of the workers regulates the pace at which the concrete mixture is pushed out while a robotic arm is 3D printing the post office.

Is 3D concrete printing is new technology

Yes, 3D printing for concrete is a very new technique. The Contour Crafting Corporation created the first 3D concrete printer in 2006. Since then, there has been a great deal of study and research in this field, and the technology has developed greatly.

The use of 3D concrete printing has a variety of benefits. First, it gives complicated structures more geometric freedom. As a result, structures and buildings may be created in ways that would not be feasible using conventional construction techniques. Second, printing 3D concrete can help cut down on material waste. This is so that the amount of extra concrete generated is kept to a minimum since it is only placed where it is required.

Third, compared to conventional building techniques, 3D concrete printing may be more effective. This is due to the automated nature of printing, which may expedite construction and reduce labor expenses.

The printing of 3D concrete is not without its problems, though. The concrete needs to be carefully prepared in order to be appropriate for printing, which presents a hurdle. This is due to the fact that accurate concrete deposition requires the concrete to have the proper consistency and flowability. Another difficulty is that 3D printed concrete still does not have the same strength as conventional concrete. This is so that the structure won’t be weakened by voids that the printing process may leave in the concrete.

Is it is the Replacement of traditional Method

No, it has some Negative Point which can be Fixed to Replace the Present Method

  • Costly: The price of 3D concrete printers is still rather expensive, making it unaffordable for certain companies and people.
  • Only a few concrete mixes are currently compatible with 3D concrete printers, which limits the materials that may be utilized. This restricts the technology’s potential uses.
  • Slow printing speed: Because 3D concrete printing is a labor-intensive technique, building huge structures quickly can be challenging.
  • Error potential: The final structure may have mistakes if the printing process is not adequately regulated. This may result in structural issues or perhaps the building collapsing.
  • Copyright infringement: 3D printing may be used to manufacture counterfeit goods, which might violate copyright and cost firms money.
  • Job losses: As 3D printing spreads, it might result in job losses in the manufacturing and construction sectors.
    Concrete production has a substantial negative influence on the environment, and 3D printing concrete can exacerbate this effect.


A promising technology that has the potential to completely transform the building sector is 3D concrete printing. Compared to conventional building techniques, it has a variety of benefits, including:

  • Greater design flexibility: 3D printing in concrete enables the fabrication of complex structures that would be challenging or impossible to produce using conventional techniques.
  • Reduced material waste: 3D concrete printing may save a large amount of material by doing away with the necessity for formwork.
    Better structural performance is possible using 3D concrete printing, which can create structures with better structural qualities.

However, there are certain difficulties with 3D printing concrete, such as:

  • expensive cost: The price of 3D printers for concrete is still rather expensive.
    Only a few concrete mixes are currently compatible with 3D concrete printers, which limits the materials that may be utilized.
  • Slow printing: 3D printing of concrete is a laborious procedure.
    Error potential: The final structure may have mistakes if the printing process is not adequately regulated.

Despite these difficulties, 3D concrete printing is a promising technology that might completely alter the building sector. The price of printers is projected to decrease as technology advances, and a wider variety of materials will be available for usage. This will increase the number of enterprises and individuals who can use 3D concrete printing and create new opportunities for its application.

In conclusion, 3D concrete printing is an exciting new technology that has the potential to significantly advance the building sector. Before the technology can be extensively used, there are still a few issues that must be resolved.
