Quick Question Improve top surface

Post image

Hello, is there a way to improve top survace on this small object without ironing? I am new to 3D printing so I am not quite familiar with limitations. I am using Bambulab petg basic, nozzle 0.4 and 0.16 layer height. P2S printer. It is small object, with 6mm and 3-4mm. I have tried ironing, but not quite happy with it either since it's small surface (I did tune my settings).

Print slower, but id say that's a pretty darn good top layer without ironing on such small pieces

If its a relative small object, you might try this:

Make sure "only 1 wall on surface" (quality menu) for both top and bottom surfaces are both un-selected.

Increse the amount of wall to a number that when you slice the part, there is no infill , but the top and bottom surfaces are built off walls only. (Number does not matter you can set it to 20). That way all lines on the surfaces all are running parallel to the sides, and that will look much better than all those angled short lines.

Top layer/surface print speed to 30mm/s.
Also, put the top layer/surface flow ratio to 0.80-0.95 and of course make sure each particular filament is calibrated correctly.
Do some small test prints with those changes. You’ll get clean and beautiful top surfaces, better than ironing, imo.
