This summer, the Czech Republic will sculpt the country’s first 3D printed house called Prvo od Burinky. The house will be a partially self-sufficient house that generates fifty percent less costs and will be built in just 48 hours—seven times faster than conventional brick passive houses.
“Compared to conventional brick buildings, 3D printing also generates up to 20 pct less CO2 emissions, which the EU aims to cut by 30 pct by 2030 (compared to 2005). It requires only about 25 workers to print one house–forty less than usual,” claims Libor Vosicky, the CEO of Buřinka.
The 462 square foot house, which will be big enough for two people, will be anchored on a pontoon. It will also feature eco-tech such as a recirculation shower and green roof. The house will be designed to last at least a hundred years in any environment, according to Eurobuild.
“In the future, the owners will be able to crush the building down once it has run its useful life, and then print it again with the same material directly on the location,” adds Michal Trpák.
The house will be printed using a robotic arm, which prints at a speed of 15 centimeters per second. The printer will work in collaboration with Master Builders Solutions. The group developed a new concrete mixture for printing that is enriched with nano-polypropylene fibers, plasticizers that improve plasticity and produce better organic shapes, and a setting accelerator.
This type of concrete hardens after 24 hours to the standard firmness of a classic family house. After 28 days, the concrete hardens to the same as the concrete used in bridge construction.
