Small bumps when printing

Snapmaker 2.0

Hi everyone! :smiley:

I’ve been doing tests for a couple of parts that I need.

These parts were printed with the same parameters, but now all the pieces have these little bumps (part A) or unevenness, which did not appear before (part B).

I already modified the speed parameters, the height in z (it had been giving me problems), the design of the piece and nothing seems to solve it.

Maybe it could be moisture in the PLA, but the place where I live is very dry.

Do you have any idea how to solve it?, thanks.

Honestly, not the answer you will want to hear, but the easiest way to solve this is to lower your expectations for FFF processes and post-process by sanding or using a filler, and painting.

You may have some success increasing the number of walls in Cura or PrusaSlicer or SuperSlicer. I have heard some ruminations SuperSlicer or similar may be capable of mitigating issues like that, though I haven’t heard a reason proposed as to why it would.
