How to deal with the overhangs?

Since I had Ultimaker2, the printed stuff always has the issue of over hangs. I'm so confused how to set software to get a smooth surface? I had tried to turn down the temperature to 185, and increase the volume of fan speed to 200%.

But it seems don't work.

Here is my setting in cure.

temperature: 200-205

layer height: 0.1

print speed: 40

travel speed: 120

Short answer: you cant get a smooth surface on overhangs.

heaps of fan, slow print speed and low temps help but you will never get them as good a normal walls

set you travel speed higher. I normally set mine to 250mm/s

30mm/s print speed will give you a really nice robot and you can print at 190. also printing 2 at once helps add extra cooling

If you want the best posible. Get a new fan cap (there are many for um2 to improve the symmetry of the air), print as @labern said and use blue tape with the bed off.

And if you want to go bananas, search on this forums for crossflow fan and design an adapter for um2
