Housing seems like a bad fit for 3D printing. The main value proposition of 3D printing is that it is infinitely customizable, so a single printer can mass produce an indefinite number of unique components.

But housing doesn’t really need to be unique. In fact, unique designs are disfavored because each new design needs to be tested and verified by an architect. Instead, housing is built up out of standardized parts, to standardized designs.

But you don’t need, and probably don’t want, a 3D printer to print out the same components over and over. Instead, it’s cheaper and easier to just stamp them out with a dedicated machine (e.g. cement bricks) and quickly assemble them onsite.
