THIRUVANANTHAPURAM: Computers taking over the construction of houses as well. The computer will give instructions according to the plan. Accordingly, the 3D printing machine will mix the concrete and construct the wall. Only the door, window and roof should be built in a conventional way. If you want, you can move the walls and build the house in another place. The wall, door and roof will be constructed separately and joined together. Costs will be reduced and no extra employees will be needed.
Nirmithi Kendra at PTP Nagar, Thiruvananthapuram is the first building in the state to be constructed through 3D printing. The construction was inaugurated by Minister K Rajan earlier this month. Tvasta Manufacturing Solutions, a startup launched in Chennai in 2016 by an IIT Madras alumni, is leading the operation. They use a 3D printing machine and concrete developed by them. The machine is patented. They had built India's first 3D-printed house on the IIT campus in five days. Walls have been built for the 275 sq. ft. house. This home is for display only. Nirmithi Kendra has plans to 'print' such buildings in the future.
A 3D outline will be created in the computer software. The computer and concrete mixing machine will be connected to the 3D printing machine. Concrete will be placed in layers one on top of the other from the 3D printer according to the design of the building. There are two workers who specialize in 3D printing. It costs Rs 2500 per square feet at present but it will decrease in future. Benches at Nirmithi Kendra are made like this.
