In the following video, Motley Fool industrials analyst Blake Bos looks at ExOne (NASDAQ:XONE), the newest public player in the 3-D printing space, and its earnings report this quarter. While the market didn't react terribly positively to the report, mostly because the company gave guidance on the lower end of what analysts expected, Blake stresses that investors should focus on the fundamentals of the business, rather than the market's short-term reactions. Blake then gives several reasons this small company probably has a lot of very exciting growth ahead of it -- but he also tells us that at 22 times sales, he sees it as a bit too pricey at the moment.
