If you look on the pictures of each printed part you can see there is use of support.
However this is minimized by the part orientations.
In most case this is all on internal faces so breaking it off isn't an issue.
The worst case are the jowl pieces but it breaks out quite well and cleans up nicely.
I would not attempt to print without support.
I have a rep 2 so support material is from the same nozzle as the main body. I don't believe it is a problem.
So just default raft and support in makerware, and have at it...
