Thank you so much for the explanation, there is simply so much to learn on 3D printing, and this forum is why I choose the Ultimaker 2.
Others have said that ABS smells bad like burnt plastic, but both my wife and I can smell PLA after 2 hours in a 4 hour print. Does anyone (or maybe everyone does already) use some type of an exhaust system?
I have only printed 3 items at 210C which wasn't bad, but I just out of curiosity and per a tech at fbrc8 (called them originally on temp and original "bead" not sticking to bed) they said to adjust head temp to 220C or even 230C.
So I printed 3 more of the same items at 220C and it makes the PLA smell almost unbearable. Maybe my nose is to sensitive, therefore in order to enjoy more 3D printing, I am looking for a good type of exhaust fan.
Bottom line though, my grand total of 6 pieces that I printed plus the robot, all turned out pretty good.
Again, thank you and the forum!
