The first 3D printed bio-based house

3D printing in construction begins to become more and more important. With the current situation of the housing sector, this technology could be the solution to make durable and replicable dwellings. This is why researchers from the University of Maine, in the United States, have used this construction method to make the first 3D printed house with biosourced materials. Named BioHome3D, the latter was developed in collaboration with MaineHousing and the Maine Institute of Technology.

About the characteristics of the house, BioHome3D is a prototype of 55 square meters. It was produced using the MasterPrint x3 from Ingersoll, the largest 3D printer in the world according to the University of Maine team in charge of the project. The latter has dimensions of 6 mx 4 mx 2 m, a print volume of 18.3 mx 6.7 mx 3 m.

A biosourced and sustainable house

As explained previously, the house is made of biobased and recyclable materials. The researchers focused on the resources coming from the forest. The location of the project is ideal, because the State of Maine is the most forested in the United States. They use these raw materials to mine wood fibers and natural resin that can be dried and mixed with thermoplastics. This is how BioHome3D was designed. In addition to being a durable dwelling, the house offers insulating performance and rivals traditional constructions.

The importance of sustainable housing cannot be underestimated. As resources are depleted and housing becomes increasingly scarce, it is important to be able to create homes relatively cheaply and quickly in a way that can be repeated for years. According to the National Housing Conference, hundreds of cities in the United States are experiencing rising house prices and young people are unconvinced about home ownership. Therefore, 3D printing could provide a viable long-term alternative to expensive and time-consuming traditional methods. Similar projects such as with the American company Azure which build buildings out of recycled plastic are an example.
