Protrusion on layer with solid infill

Trying to print two models and they both have a floor at around the 6mm height. When the solid infil is laid there is this bulge that appears on the outside even though permitters are printed first. At first I thought it was a Z banding or something as it happens at the same height for both prints, but then I printed a simple cube and there was no issue at that height. Problem persists even when printing outer perimeter first, it just makes a slightly bigger circle. Tried printing in both PS and Orca

Maybe the typical hull line effect ? How does your print look on the other side ? Look in the slicer at the layertime Is the layer time longer ?

Could be gantry bowing, try to heat soak before print

Nah. It’s heatsoaked and chamber is a toasty 60 degrees inside. Plus I ran the prints multiple times back to back, even if it was that the first time it def wasn’t the 5th 🤣 Yeah I was thinking the same tbh, but so damn pronounced. Layer time a longer as it’s somewhat big print and it happens exactly at the surface infill height. Will try with no top layers just for the lols and see what happens.

Yeah it’s a hull line issue. Hadn’t experienced this pronounced before. This is a quick print with no top layers, so no drastic layer time variation.

Hmm Guess I can try to print with super slow walls and fast solid jnfill 🤣

Layer time is not helping at all
