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?

As every layer of filament fuses with the previous layer by depositing the new hot layer on top of the previous cooler layer, it is assumed and often stated that a higher temperature increases layer adhesion. Although the effect is minimal and if you stay around the minimum recommended temp it will mostly be ok. Also, the shininess can differ, depending on the temperature and speed. Your maximum filament throughput can be lower,so the max printing speed will be lower than normal. Other than that, I haven't heard of any disadvantage if you notice that the appearance is acceptable to you. In fact, it can give some advantages like:

  • less warping / bed adhesion issues
  • better bridging
  • better looking overhangs
  • easier support removal
