2 years ago No solid surfaces is not the only option. Have you tried adjusting the support interface spacing ? As well as adjusting the support pattern spacing the interface can also be adjusted. You can set it to quite wide widths. SuSi also has several patterns like concentric and sawtooth for that last actually touching layer. Sawtooth puts little spikes upwards so has minimal contact with the object above. Personally I don't like it but it might suit you.
For example default with a 2mm interface spacing
Also I have found the reverse to be true when it comes to support. Printing 4-5 layers of the interface close together like it normally is to give an even more solid and thicker layer of interface actually makes it easier to remove, this is because it then tends to come off as one layer rather than breaking up and leaving little bits behind stuck to your model.

Behavior
I want to Minimize the Surface that touches my Models. Currently, the only options are SOLID SURFACES which bond really well to the model which is unwanted. Cura offers Zigzag, lines, grids, Triangles, and Concentric. at a LESS THAN SOLID value.
Solid works great for PVA (Soluble) Where the PVA gives the PLA a nice surface, PLA PLA is not good, even with .2+mm Z gap as to get good layer adhesion, running HOT means good bonding, even where you don't want it.
A workaround is to turn OFF the support interface, but that can lead to sagging. The support interface lets you have "sparse" supports, and the interface becomes "LESS SPARSE" but can still (if not solid) bond to the Model.
(Any other options to help make supports easier to remove that DOESN'T HURT LAYER ADHESION?)
Is this a new feature request? YES
