BioHome3D

| BioHome3D is the first 3D-printed house made entirely with bio-based, recyclable materials

Tour BioHome Press Kit

Unveiled November 21, 2022

TECHNOLOGY

Designed to address labor shortages and supply chain issues that are driving high costs and constricting the supply of affordable housing. Less time is required on-site building and fitting up the home due to the use of automated manufacturing and off-site production. Printing using abundant, renewable, locally sourced wood fiber feedstock reduces dependence on a constrained supply chain.

DEVELOPMENT

  • Designed and manufactured as a part of the SM²ART Program between the University of Maine and Oak Ridge National Laboratory.
  • Printed on the World’s Largest Polymer 3D Printer at the ASCC.

INNOVATION

World’s first 100% bio-based house.

  • Each module is 100% additively manufactured- floors, walls, and roof- which differentiates this house from current commercial 3D-printed homes.
  • Local wood fiber and bio-resin materials developed by the SM²ART partnership
  • Walls, floors, and roof are all printed, unlike existing 3D-printed housing projects.

600 square foot single-family home

  • Highly automated, off-site, modular assembly
  • Designed as separate, printed modules for ease of transportation and assembly.
  • Designed with input from the Maine State Housing Authority
  • The materials used are 100% recyclable 
  • The house is insulated with a combination of wood fiber insulation and blown-in cellulose insulation.

Technical R&D efforts leading to BioHome3D

  • Cellulose Nanofiber production including drying, functionalization, compounding with thermoplastics
  • Multi-scale modeling
  • Large, high-rate AM processing
  • Demonstrates new bio-based PLA grade formulated for additive manufacturing
  • Life-cycle analysis
