3D printing is inherently a solution to low-volume problems (e.g. prototyping, or specialized parts for niche industries). Once the desired number of units grows, it is always better to instead build a dedicated production line. So, this recent push for 3D printing houses is a bit counter productive, we need to produce large number of houses, so factories are the way to go.
