Images are renderings and the final product can look like this using order over Shapeways (or having access to Zcorp printer in metal) or in the future when they mass product home 3d metal printers :D Try using ColorFabb BronzeFill filament or CopperFill with a handful of polishing.I've never printed it but I plan doing it in the recent future. Please share your experiences. Thank you!
