With clusters and even entire neighborhoods of D-printed homes taking shape around the world, we're starting to see the technology fulfill its promise as an optimized solution for low-cost housing . A recently completed project has taken this concept into new territory as a D printed house made from % natural forest product materials, allowing it to be completely recycled at the end of its life.
In a relatively short space of time, we have seen D printed houses evolve from rudimentary shelters to some examples of luxury homes. We've also seen some green approaches that use raw materials from the earth, but most are made with cement or concrete. As part of the D printing process, these materials are extruded through giant nozzles to form the walls layer by layer and combined with more conventional wood forest products to build walls and roofs.
The newly completed BioHomeD is the work of researchers at the University of Maine and Oak Ridge National Laboratory, along with Maine Housing and the Maine Institute of Technology. Instead of cement, concrete, or some type of proprietary mortar, the house's D-printed walls are made from wood fibers and natural resins sourced from Maine's local forest products industry, as are the floor and ceiling.
“There are many technologies being developed to D print homes, but unlike BioHomeD, most are printed with concrete,” said Dr. Habib Dagher, executive director of the Center for Composites and Advanced Structures at the University of Maine. “However, only concrete walls are printed on a conventionally cast concrete base. Traditional wooden trusses or wooden truss C Level Executive List es are used to complete the roof.
Unlike existing technologies, the entire BioHomeD was printed, including the floors, walls and ceiling. The biomaterials used are % recyclable from forest products so our great-grandchildren can completely recycle BioHomeD.”
The house was created using the University of Maine's D printer, responsible for previously producing the world's largest D printed boat. Instead of typical raw materials, such as cement-like mixtures, the printer is designed to work with renewable, bio-based raw materials that use cellulose nanofibrils obtained from wood products as a starting point, drawing on the vast forests of Maine for a more sustainable approach.
This printer was used to create four modules for BioHomeD, which were assembled on site in half a day. A single electrician had power up and running within two hours. The finished -square-foot (-square-meter) prototype, located outside the Center for Composites and Advanced Structures, is equipped with sensors to monitor its thermal, environmental and structural performance during the upcoming winter season. This data will inform future designs.
“Our state faces the perfect storm of a housing crisis and workforce shortage, but the University of Maine is stepping up once again to show that we can address these serious challenges with characteristic Maine ingenuity,” he said Maine Governor Janet Mills. “With its innovative BioHomeD, the UMaine Center for Composites and Advanced Structures is thinking creatively about how we can address our housing shortage, strengthen our forest products industry and give people a safe place to live so they can contribute to our economy. “While there is still much to be done, today’s development is a positive step forward.”
