I just ran a 3D benchy on my Lotmaxx SC-10 3D printer and it came out fantastic. No stringing, melting, the dimensions look good, the bed adhesion is perfect, and it is identical to the 3D model. But upon closer inspection, there is this funny-looking scar on the print that I have noticed on many prints before. It was even on the very first print I did on the printer.

A picture of it: enter image description here

What is causing this problem and what can I do to fix it. It only happens to one side usually only once or twice. Whenever the scar happens twice, they are on the same side but far apart from each other.

Those marks are the Z Layer seams, or the point where your printer stops moving in X/Y to move up one layer width and begin on the next layer. Unfortunately, These marks are unavoidable, but you can tune them to be less severe with your retraction settings. Most slicer software available today should have a configurable option for 'Seam Alignment' that you can set to Random in order to space these marks randomly throughout the part, though this will mildly slow down the print. More advanced slicers such as PrusaSlicer are also capable of 'Seam Painting' where you can draw on your part where seam marks are acceptable. You may also be able to reduce them by setting your slicer to print External perimeters before internal perimeters.
