Sustainability of Additively Manufactured Cement-based Housing: What's our next move?

Additive manufacturing of housing has rapidly grown into a nascent industry with numerous demonstration projects recently proving the technological viability of the approach. Goals for the technology, however, are not limited to business ventures that compete in the traditional housing market. Rather, some builders and activists advocate for the technology as a potential key to solving the housing crisis in the US and abroad; though, questions regarding the scalability of economy, environmental impacts and socio-political implications still revolve around the concept. This work focuses on the techno-economics of scale for construction of housing as well as suggests what our next move is to further enable the sustainable implementation in the low-cost, adequate housing domain.
