3d-scanning small parts...

Hello community,
I am searching for a not to expensive (thousands of euros/dollars) solution (hard- and software) to scan small pieces (5 to 100mm, resolution 0.1-0.2mm) to generate data for 3d-printing (0.1mm layer high).
Anybody knows more about this theme and could announce own or other experiences?
Thank you for your efforts!
