It's quite important for us keeping right settings for printing while existing overhang.
There are lots of way to improve our quality during overhang
Adding support structure is the most intuitive way to counter the problem of droping caused by gravity and also the effect is obvious.
The temperature that filament extruded from nozzle decide the time for plastic to cool down.if the temperature is set too high,it may cause that filament spend too much time to solidify making it droop in gravity,so the most effective way to solve this problem is to decrease the temperature down.
If our model exist some overhang part,we can change the orientation of it,so maybe we can eliminate this problem from root,we just make the overhang part disappear in other oriemtation.
