Printed this cylinder as part of a larger project and there's a horizontal line that runs up most of the part. Not bad enough to scrap the project but I'm curious if anyone can explain what causes this. Using an Ender 3 printing PLA, Cura slicer.

You should also know that the seam forms a weak point (this is true even if you change your settings to make the seam less visible). If this part of your project is structural (going to be put under stress/weight/wear) in some way then you should use a setting like "Random" so that the seam doesn't line up on every layer, and just accept that the surface will have bumps.

On the other hand, if this part is visual and doesn't need to be strong, then lining up the seam like this is good and you should just arrange the part so that the seam is on the back or inside area of your project.

Good to know for future prints. Thank you. This particular part of for a toy sword for my son, we're learning this hobby together so I appreciate the insight.

If you’re going to paint it, take the opportunity to sand the Z seam off before doing it

You can also look into a setting, I think it's called coasting. It will reduce the amount of plastic extruded towards the end of the layer to reduce the seam, but keep in mind this will look better but probably have less strength at this point

I highly suggest a few YouTubers that go into things like this, like makers muse and teaching tech
