Step in the transtion from infill area to hollow areas

Hi guys,

anyone can help to figure out what might happening here?
not the first time, and not with all filaments, but sometimes in the transition from a infill area to hollow area seems to create a “step” but my feeling is that to walls in the lower part are contracting.

Without seeing an actual model to explore in Bambu Studio this is a guess.

The bottom area has a lot of material compared with the area above it.

All filaments react with heat and shrink to a certain degree. The larger the area and mass, the larger the shrinkage.

If you are going from the bottom part having a lot of material to the top only having walls, the thermal mass is large at the bottom and would be subject to a merger shrinkage than the rest of the model.

makes sense…any advise on what to approach this?

This is a reasonable article.

Hi.

I am also experiencing the exact same issue and rather than starting a new discussion, I am looking other posts first with same issue.

Have you by any chance had an improvement with this?

Thanks.
