I never really got any 'finished' prints out of it, and after splitting the company with my fellow director, I actually gave him the makerbot because I'd got a little sick of trying to get it working right, and had no real belief that it'd ever do what we wanted to get out of it. I bought it at the same time as a david laserscanner which was also a little too cheap. I wish now that I'd not bothered with the makerbot, and put the extra thousand towards a better 3d scanner from nextengine.
Initially we were trying with the heated build platform but after accidentally crashing into the platform a couple of times, damaged the surface, and then damaged the backup surface, decided that we needed to do some of our own modifications. We were having better luck replacing the default build surface with a custom copper plate but started having issues with the heating element which I gave up on trying to replace. We needed a specific £2 thermistor that we could only seem to source from the states at a minimum £15 to 20 delivery.
My overall opinion on the makerbot was that it was VERY noisy, extremely hard to perfect, and easy to damage. The change to a copper plate platform was looking alot better though, until the thermistor issue started. Basically it didn't stop heating up. Apparently Mike had a really good print going, until it started to melt
We always had one wobble point that alwasy made each print slightly imperfect. Without getting it running, we could never get any of the thingyverse tweaks printed to improve quality.
I'll see if I can get some photos from Mike, but to be perfectly honest, I'd only reccomend going down the DIY route if you have the time and patience to REALLY work at it. Over all it sucked up about £1000 and a couple of weeks to get it built, and god knows how long in failed attempts to print something.
It'll be good for test stuff, or armatures that'll have putty added covering the surface, but there's really no point in using plastrusion for high detail stuff. If you get one, start off on the right foot and buy all the tweak components from thingyverse (eg wobble arresters, tighteners etc) and print from from shapeways.
