# Perimeters

C6 always recommends using a minimum of two perimeters.

#### Perimeters <a href="#perimeters" id="perimeters"></a>

Defines the minimum number of outlines that form the wall of a model. C6 always recommends a minimum of two perimeters.&#x20;

**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.

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.

{% hint style="warning" %}
Increasing the wall count greatly increases the printing time and material usage of the print.&#x20;
