i need help with supports

[DinHN 0]

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

You might need to tweak the overhang angle setting. Looks like you've put it at 51 which might simply be too low for it to add support. Not sure why the tree supports show up, I rarely use those. But try increasing the angle value a bit and slice again, they should eventually appear for normal support as well.

 

Edit:

Of course I meant lowering the overhang angle setting. I downloaded your model and lowered it from 51 to 40 and it added supports just fine.
