Family moves concrete house from the 3D printer

In the United States, too, there is a lot of discussion about affordable housing. There are indeed huge differences within the huge country. But especially in the economically strong regions on the east and west coast, the problem has worsened in recent years. This can be remedied by building new houses and apartments. In the US state of Virginia, the organization Habitat for Humanity takes care of this. This finances people with low incomes and high creditworthiness to own their own home. The highlight: The organization waives interest and other fees. This makes buying a house affordable for people who would otherwise not be able to afford their own four walls. At the same time, attempts are being made to build the houses in such a way that the maintenance costs will later be as low as possible. Because this increases the likelihood that the loan can be repaid. State-of-the-art technology should help here in the future.

The construction time could be reduced by four weeks

Because the organization had a house built in Virginia using a 3D printer for the first time in the United States. Hotel employee April and her 13-year-old son moved into the 111 square meter building with three bedrooms and two bathrooms shortly before Christmas. The new design has a number of advantages. The 3D printer was able to finish its work within twelve hours. During this time, the outer and inner walls as well as parts of the patio roof were built. As with similar projects in Europe, the actual roof structure was then made of wood. The same applies to the pillars in front of the house. Nevertheless, the use of the printer reduced the construction time by around four weeks. This in turn reduces the construction costs. At the same time, the use of concrete in house building in many regions of the United States is rather uncommon. However, the building material has a number of advantages: It is cheaper, insulates the heat better and is more resistant to storms.

A small 3D printer enables individual parts to be reprinted

The new owner of the home from the 3D printer was overjoyed at the official opening. Previously, as a prerequisite for receiving the loan, she had to do a total of 300 hours of community service. Therefore, she partly worked on the construction site. She also helped out in one of the organization’s second-hand shops for a few hours. The young woman also illustrates the problems of the housing market. Because she has had a steady income for years and has always paid all bills. Nevertheless, she would not have received a loan to buy the house in the normal way. This is where Habitat for Humanity steps in with interest-free financing. The repayments made in April will then be used to finance other similar projects. The topic of 3D printing will also continue to be present after the building has been completed. Because a small 3D printer was installed in the kitchen. This can be used to reprint parts such as sockets or door handles.
