I think you guys have some misconceptions about the Makerbots.
The stuff they print out SUCKS ASSS.... they take a huge amount of tweaking just to look like sh1t. And if you actually want something remotely precise, you basically have to sand the blob that gets printed and sculpt details yourself.
This only refers to the makerbot,
If you have one of those German Professional Printers, those really are freaking amazing.
