@vincenzo It took about 10 hours, maybe 15. Make sure you completely read the instructions before you start, for all the components (chassis, extruder, etc) and have all the tools you'll need. I also recommend getting a thermocouple to calibrate the extruder, but that may not be as necessary if they've moved away from thermistors.
@will: Thanks for the info! We are preliminarily looking at all online resources. I was also hoping that the Thingomatic yielded a more smooth assembly as opposed to what I have seen of the Cupcake. We purchased a BFB 3000 with twin extruder heads earlier this year but it was pre-assembled. I have had to replace parts on it and get familiar with it. I'm hoping some of that experience will be useful with the Thingomatic. At this point, the build envelope might push us away from the Thingomatic and towards this. Our students tend to print larger pieces. I wish Makerbot had a machine with larger build volume. I would even do some mods to make it so.
