Maybe the rebar was 3-D printed as well....haha Seriously I don't think we can 3-D print all the plumbing and electrical and mechanical systems just yet either....

It makes sense to say that a building is partly printed, or that a printing process is involved, but to say "printed house" is misleading. As for the house with the rebars, it would be interesting to see how the print head navigated between them.
