| Abstract Scope |
This presentation describes our experience developing a thermosetting wood-based composite for 3D printing of housing and light-commercial building applications. This novel composite utilizes minimally processed wood fibers with an inorganic binder and is cured in a variety of modes, including at room-temperature. When the binder cures, it sequesters carbon dioxide, thereby reducing atmospheric carbon dioxide and helping to mitigate climate change. The rheological properties of the material are acceptable for extrusion and when cured, produce a material with strength and stiffness equal or superior to traditional particle board. We also present a comprehensive embodied energy comparison of this fabrication process to other construction methods and describe the short-term outlook for this research. |
