I'd echo a lot of these. You have to basically learn the skills of a modern machinist, including learning the quirks of the materials/machinery/environmental conditions. You can easily have something complex print for 20 hours, just to have it go off-the-rails at hour 21 and wreck the entire piece. It sounds like a dot-matrix printer running constantly for hours, the smell can be overpowering without some sort of air filtration, and the amount of finishing work that has to be done if you want something professional-looking cannot be overstated. At the end of my ownership, I realized that I simply did not need that many little plastic things that take hours to print and potentially hours to design if nobody else has created the exact same thing and shared it.
