I'm using eSUN PLA+, with a suggested printing temperature of 210-230 °C; I didn't noticed it at first and printed with the temperature of the previous PLA, which was 190-230 °C and I used 205 °C. I then printed another piece at 210 °C, and I can't really see any difference. The only thing I noticed was some imperfection I had to cut away, but I got something like that also printing at 210 °C.
Since How to fix wall separation in 3D prints (gaps in between wall perimeters)? suggests printing at a lower temperature to avoid gap in walls, I was wondering: is there any disadvantage in printing at 205 °C instead of the suggested 210-230 °C?
