Introduction: Tweaking Fan Settings in Kisslicer for Large Parts
So I flipped this part face up after i printed it. It was supposed to be flat and ended up bowing. All my settings seemed good but I figured the bowing was chased from a cooling problem.
Step 1: Kisslicer Settings
For this first part I had the fan set to 100% for all 3 choices. This can been seen in the kisslicer photo. My thinking was that the edges cooled much quicker while the middle cooled slower. This kinda made the edges pop up.
Step 2: Turning the Fan Down
In kisslicer I turned the fan down to 50% on all three settings. I thought this would allow the part to take take longer to cool and warp less.
Step 3: 50% Fan Results
Looking at the pics you can see it still warped but the warping is less. Somewhat proving my theory.
Step 4: Running With No Fan
To prove my theory I now had to run the print with no fan. So I turned it off for the entire print.
Step 5: No Fan Results
This gave me the flattest results. There was still a little warping but the least of the 3.
Step 6: Comparing the 3 Prints
As you can see all three should be the same print but the surface is rounded on the first 2. The one on the left was printed with 100% fan, the one in the middle with 50% and the one on the right with 0%. For larger thick prints with PLA I suggest keeping the fan off after doing this test.
