A prototype of a 3D printed house has popped up on Střelecký Island
Regular production of 3D printed concrete houses in the Czech Republic could start within three to five years with prices likely from 3.5 to four million crowns. The creator of the project, Michal Trpák made that announcement during the presentation of the prototype of the first 3D printed house called Prvok, which is available to the public to view, and located on Střelecký Island in Prague until the end of August.
“As for the expansion of production, we can start now. As for serial production, although I don’t like the term, we expect that within three to five years, there will be other construction companies that will start printing houses,” said Trpák.
According to him, the cost of the exhibited prototype is tens of millions of crowns. “Against a mass-produced house, it is necessary to take into account the costs of research and development. Also, it is equipped with luxury products from renowned companies. We expect that the house’s price could be produced in some basic equipment and will be 3.5 to four million crowns. , “added Trpák.
The element has three rooms and a total area of 43 square meters. It has a bathroom with toilet, living room with kitchen and bedroom. The building for a family of two is anchored on a pontoon.
According to Trpák, the printed house is suitable for being out in nature, in the city, or near the water. “Compared to classic buildings, printed houses can be up to half the cost and made seven times faster,” added Trpák. He says the house is also designed to last at least a hundred years in any environment. “In the future, the owners will be able to crush the building at the peak of its life and print it again with the same material,” said the project’s creator.
The prototype was made in České Budějovice. The rough construction was completed in 48 hours, and the work on interior equipment took about another two months. A robotic arm printed it from the workshop of Trpák’s initiative Scoolpt, through which special material flowed directly to the destination. The concrete mix for printing is enriched with nano-polypropylene fibers, plasticizers which, according to Trpák, improve plasticity and enable better formation of organic shapes, and a setting accelerator.
According to Trpák, it took ten hours to move a house weighing 30 tons and over 13 meters long. First, it was divided into three parts and transported to a port in Prague’s Holešovice on a special semi-trailer. Subsequently, he reached the destination through three locks. “At the last moment, we had to deal with renting a pontoon. Unfortunately, the tailor-made one from Sweden delayed the coronavirus,” added Trpák.
