That's done using a 3D systems Z corp printer.
If you want one done of yourself some Asda stores actually have them now so you can pay to be 3D scanned and they'll make a model of yourself. My local Asdas does it (Coryton, Cardiff), ...think it's around £60 for an adult & £40 for a child. The figures are around 4 inches tall from what I remember.
We have a Z corp printer in work and it is a cool bit of kit although I prefer SLA machines.
