Maybe printing too fast?

As a matter of fact, I did a temp tower and the best temperature was ~200d. Lower temps looked good as well but the 200d was free of artifacts. I could go as low as 190 without stringing.

I am printing now at 0.15mm layer thickness without support and I am noticing that the outmost perimeter of one of the corners is curling upwards. I guess this is the beginning of the problem. Any ideas?

have you done a temperature tower?
the lowest satisfactory temperature will be helpful, as it will allow less time for drooping...

I have not since I was satisfied with the overall quality but I can try with 0.15 mm quality if you think that this issue will be resolved. How about extrusion temperature?

Good Morning Iraklis,
Have you tried the 0.2mm quality option, or a lower layer height?

regards Joan

Hi,

I am printing a part that has a 50degree overhang that runs throughout the whole perimeter of the part. I am not able to get to an acceptable result with (picture 1) or without support (picture 2). I am using Inland PLA filament with 205 / 60 degrees and stock printing settings 0.2mm SPEED.

Any recommendations are appreciated.
