Printing Supports for a large print

[MajesticSeaCow 0]

Let me start off by saying I'm relatively new to the world of 3D printing so I do apologise if this question has been asked before.

I just got a Ultimaker 2 and this machine is amazing, I've only done a few little easy prints, but I want to move on to bigger things. I found a file for an ant man mask and I really want to print it, but before I do I wanted to know about support towers.

I've attached a image of the file and as you can see there is alot of over hangs. On Cura I have selected the enable support box I just was wondering is that it? Do I just select that box and then let the printer do the rest?

It hasn't added any additional supports to the file so which is why I'm worried about printing it.

Any advice would be greatly appreciated.

Thanks

ALWAYS look at your part in layer view before printing it. It will show the supports there.

I would flip it over - the quality of the surface will be much worse on the downward facing portion of your print so that's where you want the parts people are less likely to see.
