We've blogged before about ventures that have involved 3D printing houses.  Now, UCLA researchers are working on a 3D printing process that allows them to reuse captive carbon dioxide as an ingredient in cement.  They call their revolutionary material CO2NCRETE.

Now that they've identified a process that works, the team is thinking about how to scale up and commercialize it so the 3D printed CO2NCRETE can be marketed and sold:

We know how to capture the carbon. We know how to improve the efficiency. We know how to shape it with 3D printing, but we need to do all of that at the lab scale now, and begin the process of actually increasing the volume of material and then thinking about how to pilot it commercially,” states DeShazo, who has been responsible for providing ‘public policy and economic guidance’ in terms of this research.

Maybe someday, the 3D printed cement can be used to 3D print those houses.
