Hello, depending on the force and the application you can do modify some things:

The orientation plays an important role in the resistance that will have the model. For example, if you need more resistance to the compression you can orientate the model in the direction of the Z-axis. You can get more information on this article:  https://support.bcn3d.com/knowledge/orientation-matters

Increasing the number of walls can increase global mechanical resistance.

Some infill patterns are more resistant, for example to bidimensional efforts you can use triangles or grid patterns. For tridimensional efforts, you can use cubic or gyroid patterns.

If you still need more mechanical resistance, you can change the material. Our material selector can help you: https://support.bcn3d.com/knowledge/bcn3d-material-selector
