That is definitely and interesting point of view on the industry as a whole. One thing to consider is the extreme difference in technologies and how that effects cost to purchase. So comparing the higher end machines to the rep raps, makerbots, cubes, etc. is like comparing apples to oranges. The cost of getting into the high end machines is certainly going to stagnate the market once you start approaching saturation. Add to that both 3D Systems and Stratasys were gobbling up competitors at an astonishing rate that has only just begun to slow. I'm shocked they haven't invested more time and money into advertising the consumer level printers. It seems to me that should have begun about a year ago when 3D printing was making the rounds on the local TV news stations. Their "HP" approach to proprietary filament cartridges would be much more effective if marketed to the masses. The DIY people will never be on board with those type printers but millions of other people would if they just simply pushed advertising.
