Jeremia, the technology is already there... the problem is that solidoodle is a cheap printer and new technology always costs more than well tested does.
But yeah it is very solid and the price is low enough to justify the poor out-of-the box experience that i had as i still have saved a lot of money compared to buying ex. a makerbot replicator 2X...
which i know has a dual extruder setup, but since im currently in the designing process of making a extruder setup that can hold 2 modified e3d V5 extruders.
using a ramps 1.4 for controlling the 2 nema 14's that will be used as extruder motors.
All of this will actually allow for about the same printing area as the standard SD2/3 extruder.
