I was never really successful printing ABS on my Prusa I3 for a couple of reasons. First, the build platform was heated by a 12v circuit and you really need more juice than that for ABS. Second, the Prusa is a completely open machine and ABS simply does not like to be in the open as it cools. So I printed PLA. A lot of PLA. Used either hairspray or ABS slurry for platform adhesion (yes, ABS slurry for PLA adhesion).
The Wanhao Duplicator 4S is a completely enclosed machine and has been an animal printing ABS. I still have an occasional issue with build platform adherence but in general things stick pretty well. I have experimented with a number of surfaces other than the glass, namely FR-4 and Klapton Tape. I have also decided that some models do need to be printed on a raft.
Interestingly I have not had any real success printing PLA on the duplicator 4S! I have not tried terribly hard but for some reason getting it to stick to the build platform has been a challenge!
Enter the Ultimaker 2. I really does a nice job of printing PLA. But it's semi-open nature still can make ABS a bit of a challenge particularly in my drafty man cave. Enter my solution as shown to the right. No this is not permanent but I needed to play with ABS on the Ultimaker 2 a little before I invested in the real thing. What you see does work though. It provides a nice, warm, breeze free, build environment.
I am still struggling a little with build platform adherence on the UM2. I really like FR-4 but the sheet of it that I have is just too thin and it floated a little in the middle. Maybe some double sided tape.
It is good to have another printer that can do ABS. I guess I should work on the Wanhao and get it to print PLA!
