<p>This looks like inadequate cooling.

# How to improve quality of edge over support

(Asked by: username_0 on 2023-08-14)

I am having trouble with my print here, specifically with the part laying on the green support:

[![Print preview of a 3D model in PrusaSlicer](https://i.sstatic.net/Cl58L.png "Print preview of a 3D model in PrusaSlicer")](https://i.sstatic.net/Cl58L.png "Print preview of a 3D model in PrusaSlicer")

It seems the edge running on the supports does not stick to it and it wants to curl upwards :

I have reduced layer height to 0.1 mm and support Z distance to 0.05 mm. I am using the tight support setting in prusa slicer. The perimeter is printed at 35 mm/s and the temperatures are 200 °C and 73 °C for the bed to print PLA+.

Here is what I would like to get close to side by side with the current result. The good one is printed upside down and takes me 23h to print instead of 12h, so I would like to find a good fix for this ;)
