RE: Prints With an upward curve seems to not be coming out - Looking for feedback
as a curved surface rises from the build plate, the initial layers are at a very shallow angle and the filament droops
supports can get messy,
when I design a model I try to put a chamfer at the build plate interface and a curve above that, the chanfer at 45degrees is easily printable and then morphs into the curve.
It is not as aesthetically pleasing as a smooth curve, but usually prints much more pleasingly.

This, as Joan says, you can tell what models and designers are actually familiar with the limitations of current gen 3d printing. With curves like that there isn't room under the initial layers for support anyway due to the z gap setting and even with supports those bottom layers don't usually look nice.
If you expect them to print well then you are going to be disappointed.
