Sometimes the best thing to do is rotate the support about 5 degrees. It doesn't need to be more, I tried 10 and 15 degrees and was just wasting filament. You'd also be surprised sometimes what will print without supports.
I don't know if Cura supports angled supports. In PrusaSlicer you do have to turn on expert mode.
One more tip... Large flat surfaces on the bottom benefit from the Hilbert Curve pattern. It takes a while to generate but it's worth it. It keeps corner lifting from going as far because the lifting force can't get a grip on the next piece. Imagine legos on a base. If you lift the base, thr base will lift all the legos. Now take the base away and try lifting the legos. Legos will want to stay but some will still lift. Hilbert Curve kinda does that.
I have a Prusa Mk3 that's my workhorse. Open source design and it just works.
I'm actually going to be doing a few lessons with our high schoolers on AutoCad and 3D printing next week. We are going to design and print bridges. (The fun part should be cutting out the support structures that are printed too) ...
Luckily, being in a school and with all those generous STEM g... more
PrusaSlicer makes support removal easy.- Puckdropper,Sat Jan 08 2022 9:09am
I know regardless I have to re do it in gdrem format for my printer to take it. Which is kinda annoying but whatever. So if it can save the STL with the supports already drawn in I guess that would work?
