The Pursa i3 seems like a great printer to me, all in all. I'm looking to buy either that one or an Ultimaker Original. Maybe a Solidoodle 3G but I've heard it has a few issues. The noise samples from Mr. Luigi are pretty loud! But I trust this can be reduced a lot. It would be a problem for me since I would want to run the printer overnight and not wake up myself or the neighbors (it seems that they sleep in the room next to my office, and the walls are thin). Could the printer get very silent if you set the speed to very slow, but still fast enough to, say, print 10cm3 an hour?

Also a requirement for my printer is that I should be able to print ABS, PLA, and Nylon (or another more flexible filament) - and this printer seems to not be able to do this with the available nozzles. Or could the nozzle for 1.75 mm filament handle these 3 materials?
