At the University of Maine, a groundbreaking innovation is taking shape: a massive 3D printer that uses wood waste from local lumber industries to create cozy, sustainable homes. In a state grappling with a severe housing shortage, this technology offers a promising solution. Researchers are optimistic that their efforts could significantly address the growing demand for affordable housing in the region.

3D Printing: A Response to the Housing Crisis
Maine is facing an escalating housing crisis, with estimates suggesting that 80,000 new homes will be needed over the next five years. The Advanced Structures & Composites Center (ASCC) at the University of Maine has developed a novel 3D printer designed to meet this urgent need. By using sawdust to construct entire houses, this technology could drastically reduce construction times. This innovative approach represents a significant step toward providing faster and more sustainable housing solutions.
Record-Breaking Technology
The 3D printer at ASCC has earned a Guinness World Record for being the largest polymer 3D printer globally. Capable of printing a house with a footprint of 600 square feet, the printer can create structures up to 96 feet long, 36 feet wide, and 18 feet tall. The machine processes 500 pounds of bio-based material per hour, allowing it to print the walls, floors, and roof of a house in just 96 hours. Researchers are working to halve this production time, aiming to print a complete house in just 48 hours in the near future.
Innovation Meets Tradition
The homes produced by this 3D printer, known as “BioHome3D,” feature a modern Scandinavian design that seamlessly blends with Maine’s natural aesthetic. Unlike previous 3D printing projects, this technology creates the entire house, including the roof and floors. The ASCC team is currently focused on integrating wiring and plumbing directly into the printing process, ensuring that the homes are ready for immediate occupancy upon completion.
Focus on Sustainability and Efficiency
By utilizing wood waste as a building material, this 3D printing process is both environmentally friendly and cost-effective. The potential of this technology to revolutionize the construction industry is immense, offering sustainable and affordable housing solutions. The University of Maine’s innovation highlights the successful combination of traditional craftsmanship with cutting-edge technology to address pressing societal challenges.
