Curling or rough corners

Small areas in your print have similarities to overhanging issues. The plastic warps and strings are hanging out of the object. This issue can also be called “Warping at Overhangs”. It appears if the part is not cooled plenty and the extrusion temperature is too high.

There are a few things you can do against this special problem:

Adjust the nozzle temperature
Part cooling fan
Adjust the nozzle temperature

Set the nozzle temperature 5-10°C lower and give the plastic the time to cool down. In this solid state the hotend will not deform this layer by arriving for the next one. For further advises, please read the solutions for “Extrusion temperature too high”.

Part cooling fan

To avoid curling, a good opportunity is to raise the fan speed percentage. The plastic hardens more quickly, so that the next layer does not get deformed before it has been cooled.
