Diffrent surface qualities

I’m trying to get clean surfaces on my models. Now when I print 4 at once, I get different surface qualities. I haven’t figured out why this is happening.



At the top left I have an almost very good surface. On the model at the bottom left I have overextrusion in dark blue and underextrusion in the other shades of blue. All models are set up the same, of course.
I have no idea why this is happening. I could put the printer in a case or adjust the flow ratio for each model. But I find it strange that the models have different quality. Does anyone have any ideas or similar problems?

kind regards!

Ironing might be a way to equalize the differences to some extend.

am i seeing the infill lines cuz i see them are you refering to the infill lines thats normal

I tried ironing and it helped a little, but the quality didn’t improve much. Above all, the surfaces still looked different.

If you mean these lines, they are not fill lines. This line is created by the surface pattern. I don’t know at the moment why we can see them.

yep thats the infill lines ìf you set the infill density higher it will disappier
