For different applications there are different priorities and for some the manufacturability is specially high. Therefore, it would be nice to push designs in a direction where the manufacturing gets easier without costing to too much performance regarding the efficient design and material allocation.
...
Low has less impact and the design is close to an optimisation run without Support Reduction. In critical areas the support amount gets reduced. Medium and high have more impact on the design and reduce the needed support amount significantly.
By default an overhang surface is determined if the angle falls below 45° in relation to the baseplate. The overhang angle can be changed with the Advanced User Settings.
In the next images an example part is used to display the difference between results of the strategies.

In the following graph the influence of the strategies is illustrated. It can be saved up to 78% 80% of support volume with activated Support Reduction. As a trade off the mass of the part increases. Because more material is used the part gets a little bit stiffer.
