"Seam" in cylindrical prints

A little "seam" or in other words a little bump is always present in my prints in the shape of a cylinder. It is formed when the extruder moves to another layer. Is that unavoidable? Thanks.

Your nozzle pretty much puts out a squished cylinder which is round at either end, so either the round bits overlap at the start end point, leaving a bump, or they just meet leaving a slight void. To get rid of it you'd need a helical tool path, and to build the outline in a single pass, you could probably do it for a class of objects with specialist software.

Cura has a joris the edge option which does exactly that for single walled objects.

Out of interest what does it do if the print has more than one island?
I assume it just doesn't generate the spiral tool path for that part of the print?

Interesting question. Physically it could only work with printing pieces individually, which is supported. In slic3r anyways.
