I have had the AW3D HD for awhile now and can say without reservation, I am completely happy with it. I had the MakerBot Replicator 5th Generation but returned it because of all the problems with the Smart Extruder and homing and bed leveling issues.

The AW3D HD's printing quality is superb … far superior to anything that came out of my MakerBot. Add to that it's ability to print in over 13 different materials makes for a very versatile printer. It's fast, precise, very sturdy and very easily maintained. I don't think the clear acrylic case is going to be a problem at all. It's thick and well made and the fit and finish is tops. Yes, there are a lot of 3D printed pieces, but I don't see that as a detriment. If a piece breaks, Airwolf easily supplies them for the HD. My closed source Makerbot would have been/was a nightmare if something broke and needed to be replaced.

The hot end is very sturdy and I have had no clogging issues at all. MatterControl software is easy to learn and includes 3 different slicing engines to suit your needs. All in all, I think you won't go wrong with the HD. I am very happy I decided on this printer … I can see it lasting for years and it growing along with me as I learn more.
