Using a completely customizable support system - you can change the thickness of the supports as well as add or remove them manually - Simplify 3D makes sure your models are always scar free and look their very best. While Cura struggles to produce good support structures Simplify 3D creates masterpieces. I use it often to reduce the infill in larger areas of the model to help speed my prints up and it works great. You can use them to adjust settings on a per layer basis such as temperature, infill percentage, and even layer height to maximize your print quality and minimize your print time. Processes on their own are extremely helpful when printing complex models. These profiles can also be exported and imported from other people, allowing the community to share best practices with each other in a way that's just not possible with Cura. Using a system of profiles and processes, Simplify 3D allows you to make specific settings for different printers, filaments, and even models, then quickly and easily store them for later use. Simplify 3D is all about options and saving those options to use later.
