How to print myself?

[wenganxiang]

Hi everyone,
Have you seen this kind of dolls before? They are dolls of real people, and made by 3D printer!
In the past, we can make cartoon images of ourselves. Just take a photo and edit it with software such as Photoshop or others. It’s only a 2D model and easy to do.
However, a real-person doll is totally different from a photo, it’s very cute and exist in 3D world--the real world, so I can touch it, put it on my desk or other places, which can also be a good gift.
Now I only have a Geeetech 3D printer, it can print most 3D objects. But how to do a whole body scanning, get and edit my own 3D model, then print myself?
