Individual parts of the houses were printed separately and then brought to the building site, where everything was assembled and insulation was installed. The walls themselves are hollow, but are comprised of a zigzagged pattern in order to make them extra strong. The design makes the house more flexible rendering them more resistant to earthquakes.
Printing a house doesn’t only save time — according to Winsun, it also reduces waste and costs. The buildings are manufactured using a special ink comprised of building waste, cement, glass fibre, sand, and a special hardener, which ensures 30 to 60% less waste than a regular building. There’s also a 50 to 70% cut in construction time, and 50 to 80% lower cost of construction thanks to the lack of employees requiring payment. In the end the house costs about €140,000.
