Make the top surfaces of your 3D prints (almost) perfectly smooth with Cura “Ironing” setting

o you want to improve the quality of yours 3d printed Parts.

the “Ironing” setting can help you get smooth surface of your 3d printes..
The setting can tremendously help with the topmost layer surface finish when printing objects with big flat areas on top (in my test case, it was a keychain I was making for a friend). For “curved” objects it should not matter.
Here’s how it works: when the topmost layer is finished, it REPEATS it without moving the print head higher. The head moves in a more dense zig-zag pattern (customizable, default 0.1mm) with much lower extrusion multiplier – not sure if it was 5% or 10% by default, but in my test case I used 10%, and it worked flawlessly.
This helps smooth out any surface irregularities and gaps on the topmost layer, hence the name: “ironing”.
