The consumer printing market has been highlighted as the shining star for 3-D printing companies. Analysts are forecasting annual growth of 15% over the next eight years, and it is expected to reach $1 billion-$3 billion market size by 2020. This strong industry growth is the prime reason that Stratasys (NASDAQ:SSYS) and 3D Systems (NYSE:DDD) have been attacking this market. 

These two companies aren't the only entrants in this extremely competitive market, though. You'll find 67 Kickstarter projects based around the technology and numerous private companies offering printers as well. In the video below, Motley Fool analyst Blake Bos offers his insight on the competition between 3D Systems' Cube and Stratasys' MakerBot printers, and what investors should watch for going forward.
