Thanks BlackBird now I know completly how this can be done : http://www.etsy.com/shop/lulubugjewelry
(It's not 3D printing but hand formed silver metal clay with the indentation stamped in).

That's really cool BlackBird, and it's amazing to be able to have it printed directly in silver!

The galvanizing turned out great!

good work blackbird, I have some pieces on order from shapeways has well, designed in MoI. :)

Shapeways, print the out the model in wax, then produce a mould to cast the silver.

backbird, does the blackout last long?.

""Shapeways, print the out the model in wax, then produce a mould to cast the silver.

I doubt that. The surface looks much more like a selective laser sintering to me.

yes the black-dark last long. as long as you dont sand, scratch or polish/buff it. its a natural oxidation. by some time all silver will turn dark. cos of the Oxigen and some kind of sulfer in the air.

and yes they first build a Waxmodel and then they put it together with some other wax-models in a "waxtree" then they use some clay or sand to build a mold. they melt out the wax and then fill in some silver. i dont know if the surface is that coarse of the Mold-Sand or if the wax-modell was Laser-sintered. i dont care about that cos the front side was very clean/glossy.

They look great!

Their shape reminded me of the characters in these adverts that we used to have here in the UK in the '70s
