sls (selective laser sintering)
it uses nylon powder and a laser to create items layer by layer - similiar to fdm (fused deposition modelling/manufacturing) but as a complete layer is laid down each time (building a solid cube of powder with the sintered object inside) you have very few restrictions to what you can make - shape wise.

shapeways use sls.

But from a purely aesthetic viewpoint (something I rarely see the point of) your ceramic fountain will probably ALWAYS look better :-)

lol what the hell have shapeways done to their website ?
Absolutely impossible to find out what materials they have without either asking for a quote or uploading a model.
Sheesh.
