Printing a Unicorn and Discovering Support Structure

I promised my daughter that I would print a unicorn.

I found this model on thingiverse.

It is great, but how is the printer able to make the parts without something below?

Actually, the slicer generate support structures to do this.

Note that this consumes PLA, so you may want to rotate the model to make it consume less.
