In the following video, Motley Fool industrials analyst Blake Bos takes a look at Stratasys' (NASDAQ:SSYS) earnings report. While the company beat analyst estimates and gave stronger guidance than expected, Blake points out that with a stock like this with such a long-term investing thesis, we're going to want to look at more long-term measurements of success than just a strong single quarter.

Blake also identifies his favorites in the 3-D printing space, as we start to see all the ways in which this new technology might be adopted.
