Patterns

Patterns determine how material is distributed within a print. Different patterns can affect strength, flexibility and print speed using the same density setting.

There is no one-size-fits-all solution, as the best pattern depends on the specific print and its requirements.

Many patterns may look similar and have similar overall specifications, but they can behave very differently in practice.
As most settings in 3D printing, experience is the best way to determine which pattern works best for your specific needs.
