Makerbot has the most popular 3D Printers on the planet, but yet to me they are using a technology that will eventually die out. I don't foresee filament based printers ended up the future of 3D Printing. It will either be SLS or SLA, with either resins or powders that will end up taking off.

Why don't we see MakerBot releasing any of these types of 3D Printers?
