Yeah, 3d printing is still a solution in search of a mass market problem.  Quality isn&#x27;t good enough to make &quot;consumer&quot; parts yet and still too fiddly, and not 10% of the country needs to prototype, much less the <i>whole</i> country.<p>Eventually someone&#x27;s going to figure out exactly what they&#x27;re perfect for and things will really go bananas.  Until then they&#x27;re fun but only useful to a pretty limited set of people.
