Recently been using my Rostock Printer. The quality has not been as good compared to my other printers. This is the first time I’m dealing with ABS; I’ll have to purchase some hair spray to help with the piece sticking to the bed. I do notice that it bubbles a lot leaving gaps sometimes. And the quality is good towards the bottom of the piece but it leaves gaps during the last few layers of the piece. This was a model of the Death Star from Star Wars made of three separate pieces.
