Flashforge Creator Pro User Manual page 42

Features：Full coverage of supports improves the model stability. But the supports on the surface
are difficult to be removed and will definitely reduce the print quality.
Treelike Support Structure：Suitable for models with small area overhang(s).(You are suggested
printing a raft)
Features ： Treelike support structure is proprietary to Flashforge Corporation. And this structure
can save support material and can be easily removed. However, compared with the linear support
structure, it's of less stability. So you are suggested to manually add more supports after auto-
generating treelike supports.
