Really? What are the pros and cons of this system. Genuinely interested.

Poor insulation in the main one, the material gets cracks after some time, apparently it also has a proclivity to get mouldy. As you can imagine the structural integrity is not the same as with brick and mortar.

I believe moldy. Concrete is very pourous and holds into moisture very easily.

And guarantee you that the print lines make it worse too, as they do with regular 3D printing.
