One of the highest-growth areas of 3-D printing is the consumer industry, but finding data to see just how fast this category is growing has been nearly impossible for the average investor -- until now.

One of the two 3-D printing juggernauts, 3D Systems (DDD 1.98%), reported earnings on Tuesday, and investors were able to see how the company's Cube line of 3-D printers were performing for the first time. The lovable little printer churned out $25.8 million over the past nine months, an increase of 226% compared with the prior year. But how does that compare with 3-D printing juggernaut No. 2, Stratasys (SSYS 2.15%), and its Makerbot brand of consumer printers?

In the following video, Motley Fool analyst Blake Bos goes over the Cube's results, compares the Cube results with those for Makerbot, highlights a possible new product for 3D Systems, and tells investors what to watch for going forward.
