Why have custom profiles?

1. Filament settings: While using REDD filament the settings will be dialed in for you, but in the case of 3rd party filaments you may need to change the temperature settings as per the manufacturers' requirements, having a set profile for a brand of filament will help you avoid the repetitive task of having to change settings over and over again
   
2. Experimentation: Cura has a large number of features that are hidden away from the basic settings, these can be can access in the expert mode. Make changes to advanced settings can be saved in a new custom profile to keep track of the changes made.
   
3. New features: Cura releases new features into their slicer every few months and this gives you an opportunity to try them out, using custom profiles again we can test these features without disturbing our current settings.
