The Las Vegas Consumer Electronics Show is arguably the most overwhelming technology spectacle of the whole year. Companies from all walks of life show off their latest and greatest products for the world to salivate over. Trying to keep up with the sheer magnitude of announcements will make your head spin.

This year was particularly a big one for 3-D printing, which had its biggest showing yet, with 28 exhibitors in all. While there were certainly some interesting start-ups showcasing their newest products, the real spectacle was how 3D Systems (NYSE:DDD) dominated Stratasys' (NASDAQ:SSYS) MakerBot in the consumer and "prosumer" 3-D printing space, with an arsenal of new and affordable compelling offerings.

In total, 3D Systems announced more than a dozen new products and partnerships, allowing it to really beat out MakerBot in terms of price, functionality, and professional features. In the following presentation, 3-D printing analyst Steve Heller explains exactly how it all went down.
