Perimeters

This setting determines how many contours will be drawn around the print on every layer.

C6 always recommends using a minimum of two perimeters.

Perimeters

Defines the minimum number of outlines that form the wall of a model. C6 always recommends a minimum of two perimeters.

Increasing model strength The strength of a model is mostly defined by the number of perimeters (not infill). If you want to have a stronger print, increase the number of perimeters.

C6 - Different wall counts example.

The number of walls is a major factor in how strong the print will be. Since the walls are adjacent, they can reinforce each other leading to a stronger part. For larger prints, this can be a much more effective way to get a strong object than adjusting the infill, depending on the shape.

Generally, Increase in wall count helps to reduce the shine-through effect where the infill pattern is visible on the outside. It also Improves overhangs and makes the model watertight more easily.

Increasing the wall count greatly increases the printing time and material usage of the print.
