The second-largest 3-D printing company, Stratasys (NASDAQ:SSYS), reported third-quarter earnings on Thursday morning, and the results were well received by Wall Street. While this sent shares higher in early trading, investors should look much deeper than Wall Street estimates in order to make sure the company's long-term fundamentals are still intact . Investors in 3D Systems (NYSE:DDD) should also take note, as Stratasys's newly acquired brand, MakerBot, is competing directly against 3D Systems in the consumer printer category.

For Stratasys, last quarter's results were packed full of information but five key areas were of special interest. These include: MakerBot's results, organic revenue growth, profit margins, technology developments, and share dilution concerns.
