Low Maintenance, Reliable, Good Print Quality
I've used a lot of different desktop 3D printers, assembled some professionally, and used a few Dremel 3D20s so I knew what I was getting into when I bought my printer. It's a good value and if you want to print PLA day and night, this is your printer. I've never had a jam or clog with this machine, ever (knock on wood). I printed out a mod for the extruder, so now I can print flexible material just as easily.
The Dremel build surface is like BuildTak and works very well. The bed is easily removable. I bought a second bed, so I can keep on printing, while I'm removing a print. It's pretty quiet. Print quality is very good and squishing the first layer a bit leaves a smooth bottom layer. What I like best about this printer is that it's reliable.
The downside... The desktop software isn't the best, but it works great with Simplify3D. Bed leveling can be a little annoying and the acrylic beds aren't perfectly flat, I find are a little high in the center.
Note: The CF card attached to the main board always gets unseated when this model printer ships. You'll have to get to the main board, take out the CF cards, remove the hot glue they use to secure the card in the port (I know, crazy) and pop it back in. Should work fine after that.
Overall a great printer and I'm very happy with it.
