First thought it was sped up but looking at the camera movements it seems to be real.

I know some people who literally just let their filament lay around for ages and they say it’s fine, whilst others told me that keeping it vacuum (or in some expensive camera gear box with humidity control) is the best for it and absolutely noticeably gives a difference over time.

Looks like people either don’t care or go crazy about keeping it dry. Does this vacuum thing help? I guess I’ll just do it even if it only gives me the slightest feeling that it kind of protects my filament and prevents my prints to fail due to too wet filament 😅

So this is my first (actually second but first large) PETG print. I have Ender 3 V3 SE. I use a Sunlu S2 dryer (with upgrade so it can get rid of the moisture). The PETG is from Copymaster3D.

I use PrusaSlicer with a profile for the E3V3SE I found online. It has been awesome for PLA. And I manually made a PETG profile for it, as that was not included. I first struggled a bit with it as it wouldn’t stick to the bed, but once I lowered the printing speed to 35mm/s, it finally would stick.

I printed this cup holder for my car and it is functional so I am happy. But as you can see, the top isn’t smooth but rather rough, and the inside of the wall is not smooth but shows a lot of lines.

Im very new to 3D printing and PrusaSlicer has a LOT of options so I’m a little bit overwhelmed. I of course did a quick google and Reddit search about what I could do about this, but as I said, it’s a bit overwhelming.

Hope someone can tell me in easy language how I can fix these two ‘issues’ to make my PETG prints look nicer.

If I need to share any more settings, please let me know.
