Hello, I am quite new to 3d printing. I mean I have used UP Studio before to 3D print but not to the extent that I needed to use support structures before as much as this one. The project I am doing is on a turbine and I am printing the blades. I split the blade into two parts using slic3r and tried to check how many grams I need of my filament to print one complete set of 3 blades. I placed the half-blade into a Creality Ender 3 Pro and sliced it. But there were no support structures? That does not make any sense to me because the blade is overhanging and when I check the preview, there weren't any sort of support. When I changed the support structure to tree then it properly shows it. I don't really know how to make any sense out of this, hope there is someone that can help me out on how to efficiently 3D print this half-blade.test.3mftest.3mftest.3mftest.3mftest.3mftest.3mf
