Remember BioHome3D, the 100% bio-based 3D printed home built at the end of 2022 as another solution to construction crisis? It demonstrated its viability by withstanding one year of outdoor testing.

As a reminder, the 600-square-foot (55m2) home was printed at the University of Maine’s Advanced Structures and Composites Center (ASCC). It was created entirely with wood residuals, bio-resins and wood fiber insulation. Due to its renewable materials, the home, which includes one bedroom and one bathroom, is fully recyclable and acts as a carbon sink.

During its inaugural year, BioHome3D endured one of Maine’s most volatile weather years, including reported temperatures ranging from 1°F to 105°F (-17°C to 40°C), extreme wind storms that caused blackouts throughout the state and a number of snowstorms. It performed very well under rain, snow, temperature cycling and hail.

Sequestering 46 tons of carbon-dioxide for each 600-square-foot unit, BioHome3D stands as a pivotal solution for the construction industry. This technology addresses both operational and embodied carbon, and sets precedents for both sustainable construction material production and manufacturing.
