Maine: start of serial production of 9 bio-printed houses

University of Maine launches production of nine 3D-printed homes with bio-based materials

The University of Maine moves from the experimental phase to serial production of 3D-printed homes. The university's Advanced Structures and Composites Center (ASCC) will build up to nine homes in the Greater Bangor area, in collaboration with the nonprofit organization Penquis. The homes will use composite materials largely derived from the residues of Maine's forest industry.

The project represents a qualitative leap compared to the experimental BioHome3D house presented in 2022. The goal is no longer to demonstrate technical feasibility, but to verify whether the process can be repeated, accelerated, and transformed into an economically sustainable production system.

From prototyping to serial production

The project marks the transition from a technological demonstration to a real industrial process, with the ambition of creating a “Ford factory of houses”.

In 2022, BioHome3D had demonstrated the possibility of printing not only walls, but also floor and roof using composite materials of biological origin. This approach differs from construction 3D printing systems based on concrete, which typically produce only vertical elements.

Now the question changes radically. The University of Maine wants to understand whether the same process can be replicated industrially.

The executive director of ASCC, Habib Dagher, described the vision as a “Ford factory of houses”: homes produced industrially through a highly automated process and subsequently transported to the installation site.

Three-phase development strategy

Production will not occur in a single solution, but through three successive groups of homes, each optimized based on previous results.

The nine homes will not be produced all together with a definitive configuration. The University of Maine plans to proceed in three successive phases.

Each group of houses will serve to collect data on material behavior, production process, assembly, and building performance. The results obtained will be used to modify the next group.

This strategy allows for the progressive introduction of improvements rather than merely verifying the repeatability of an initial process. The project simultaneously becomes a housing program and a true pilot production line.

Forest materials and social purpose

The homes will use materials derived from the local forest industry and will be intended for people in housing vulnerability conditions.

The composite materials used largely come from residues of Maine's forest industry. This approach creates a direct link between local resources and housing production, valorizing industrial waste.

The homes will be installed in the Greater Bangor area and intended for people who are homeless or at risk of losing their homes. Collaboration with Penquis, a nonprofit organization, ensures that the project has a direct social impact.

Industrial prospects

The project aims to demonstrate that 3D printing of homes can become a scalable industrial process, not just a technological curiosity.

The final goal is to create a production system that can be replicated and scaled. The metaphor of the “Ford factory” evoked by Dagher is not accidental: it recalls the transition from artisanal production to mass industrial production.

If the project succeeds, it could pave the way for a new mode of housing production. A system that combines automation, sustainable locally sourced materials, and production speed.

The division into three phases allows for systematically addressing technical, economic, and logistical challenges. Each iteration will provide valuable information to optimize the process toward industrial production.
