Very nice indeed.

/printed in stainless steel/ ?? I think you mean something else than I
do read... :-)

That's the marvels of modern 3D printing.
AFAIK shapeways actually print a wax model, and then die-cast it in
bronze steel; but there are 3D printers out there that work directly
with bare metal, using either sintering or depositing processes.
You can also get your stainless steel with a gold plating, and solid
sterling silver is another option (they do use some direct process for
the latter). Or how about glazed ceramic?

Really? I thought it went through a casting process... But then of
course, I have not been following closely the developments of the
technique.

all kinds of things can be 3D printed now-a-days :

Google "DMLS" - most rapid prototyping houses will do it, our local one
does.

For creating objects from stainless steel, Shapeways actually does not use a
die-cast either. As far as I understand it, glue is printed on thin layers of
metal powder, which results in a fragile structure. This then is post-processed
into a strong metal object. I assume by first removing unused powder and next
hardening it, presumably by applying heat, but now I am just guessing. Some
details can be found here: https://www.shapeways.com/materials/steel
Anyway, I find it fascinating that you can model something from your own home,
and have it subsequently realized in 3D, in a whole range of materials. This was
the first object I had printed in stainless steel, but I have used 3D printing
before to prototype a puzzle I designed. At that time, I used a cheaper, plastic
material. Cool stuff.

If it makes you feel any better, if it weren't for the fact I deal with
them for my job then I wouldn't have had a clue what was possible either...

BTW, they've just announced gold plated brass as their newest material.
Nice smooth finish, somewhat like the silver.
