The kinect can be picked up for <£20 and when paired with a program called Skanect, can produce excellent 3d scans.
Revolving around the subject, the kinect records 3D mesh geometry of the subject. This can be then taken into a mesh editing program to be cleaned up.
In this instance, the aim was to 3D print the subject. For this I used Rhino and its mesh tools to create a water tight mesh.
I then used a REPRAP printer to create the final piece.
