Huh. It still seems wildly premature at this point. In between cost, difficulty of use, and limited utility at the moment, I don't see many uses in home construction/repair quite yet. I mean, living in an old house where many elements are non-standard and custom solutions are required, I can think of all sorts of potential uses. But either the cost means that other alternatives are cheaper, the lack of files makes it impossible (there's just not yet the critical mass of users to provide just the right files you need for a particular purpose), and the limits in size and/or material just don't allow it (being able to print out custom moulding, or being able to print in plaster, for example, would be amazing).
