Of course things can be made by craftsmen, maybe cheaper. But it does not
hurt to have new perspectives.
3D printing is new. Basically a printer receives input from you and lay down
powder of metal or ceramic or plastic (rather than the traditional ink
powder on paper) one layer at a time, which is consolidated by adding glue.
The next layer then starts. The whole process is pretty quick actually.

Quote:
"Shapeways, a company that allows people to print 3-D objects, announced on
Thursday that it will now let you print things in a ceramic material that is
'food safe.' Until now, 3-D printers have primarily printed in plastics or
other materials that you wouldn’t want to eat off of.
"Ceramic 3-D printing works by adding multiple layers of ceramic powder to
create an object, which is put in an oven to dry and harden and then fired
in a kiln at high temperature. Finally, the object is glazed to make it
smooth.
My comment:
(1) The company's web site shows (i) its 3-D printer can work with plastic,
ceramic and metal, (ii) it will print it--and bake it in case of ceramic--
for you, instead of selling the printer to you, and (iii) check out "jewelry
" in the left column (headlined "Product categories") of the home page.
(2) "In March 2007, Shapeways started working for the Lifestyle Incubator of
Philips Electronics in Eindhoven, the Netherlands." In September 2010 it
moved headquarters to Manhattan.
Eindhoven
http://en.wikipedia.org/wiki/Eindhoven
(The name Eindhoven derives from the contraction of the regional words eind
(meaning last or end) and hove (or hoeve; a section of some 14 hectares of
land). "Eind" is toponymically a common prefix and postfix in local place-
and streetnames. A "hove" was a parcel of land that might be given in
leasehold to private persons such as farmers by the local lord. Taken in
conjunction with the fact that a string of such parcels existed around
Woensel, the original location of Eindhoven may be understood to be the "
last hove on the land of Woensel")

至少去年还不是这样，难道今年都和DC大使馆统一步调了？
应该是不能代办的
