I designed these badges and had them 3D printed by Shapeways. The first set is printed in sandstone, and the other set was printed in alumide. For the alumide badges I painted them and then used liquid polymer clay to create the glassy filled-in areas.
I have also printed Johto and Sinnoh badges, however they require additional work to complete.
