Yes, I actually have the Ultimaker set up in my living room and the fumes when printing in ABS were quite noticeable and smelled toxic. However, I thought it wouldnt be so bad if I kept the windows open and wasnt in the room while printing.
Worst thing for me was warping and lifting of the corners while printing. I read about a method that included dissolving some ABS leftovers in acetone and then using it like a spread on the printbed for better adhesion. Never tried it though, the clogged up nozzle threw me off immediately. I had to use the atomic method 10 times before all the new material came out clean. For cleaning the nozzle with acetone you would have to remove the nozzle though, right?
After all, I am still learning and my results in PLA get better each day. The only downside to PLA so far has been its low melting point. I worked on a model of the Enterprise from Star Trek: The Original series. While painting it with my airbrush kit I used a blow dryer to speed up the dry times between layers. The material weakened pretty fast.
Other than that, I love printing in PLA. I felt that I could never get such fine results in ABS.
