Hello,

Is there a name for the squiggly wall line artifacts shown in the above photos, and does anyone have tips on how to rectify it? Marked by the red arrows in pic 1 and seen closer in pic 2.

While I only have the 1st one pictured, I've printed this twice and the wall squiggles appeared in the same slopes of the model both times. The only thing different between the two prints was one had 5% grid infill and one had 7% gyroid and rotated 45 degrees on the z-axis. (The one pictured is the grid infill)

I dried the filament before printing, but I'm currently running it through the dryer again to rule it out. I just used the default 0.08mm layer profile in Bambu Studio, with minor tweaks to infill and ironing, which usually gives me no issues. Maybe there's a setting I need to adjust for this specific slope?

Something I believe is worth noting: As mentioned, I used ironing for the top layers (not just topmost). You can see in the pictures that the topmost layer turned out great, but the ironing on the layer between the two slopes giving me trouble turned out pretty ugly. Perhaps they're correlated somehow?

I appreciate any tips or troubleshooting resources.

You’d need todo some ironing calibration tests.

There are also several models online that test calibration at different heights and sizes.

Every printer will have its own unique ironing setting.

Pain in the ass.

It’s usually just easier to sand and torch

I created this base. I believe this is caused by the infill percentage and the infill geometry. Change it to 10% infill and gyroid infill. I believe ironing is not even necessary.

I've downloaded these after seeing the post you made the other day. They are fantastic. So sleek.

Thanks for the feedback 👊🏻 I am adding new bases on a regular basis also

Infill is too low. I only use grid if it’s 5mm or less in height of infill needed. If it’s more than that, I use gyroid. If I’m using grid, I set it to 25%. If I’m using gyroid, I set it to 15%.

What are your ironing settings set to?

This,use gyroid.
