I have a part with hair strands, such as the Hairy Lion on Thingiverse, and I want to print it on a Stratasys F370. The thin strands are intended to print without support, bridging to the exterior wall. Although the bridges are quite long, it doesn't matter if they sag, because they will be heat-treated afterwards.
But when I open the STL file in GrabCAD Print, the slicer gets over-protective of those long bridges, and inserts soluble support for every one. As well as being a huge waste of support material, it would take ages to dissolve out all of that support, and it's completely unnecessary. However, there are other parts of the model that overhang and do need support, so I can't just disable support completely.
How can I avoid supporting these bridges?
