The ring is especially nice, and I am in love with keltic knots etc.
thank you all.
Modelling the ring was really simple. At first i created one of this celtic symbols (triquetta), subdivided and subpatched it, y-mirrored and cloned it 10 times in a row, and then i used bend to form it into a ring.
About preparing the models: shapeways has a very comfortable and advanced system to autocheck your models if they are printable or not.
So your celtic part wasn´t welded right? it was just enough with the parts overlapping in order for it to print as joined pieces? I reckon that was the case?
So what do you expect to do by purchasing your own printer? the ability to skip shapeways(though I guess not since it deals with other techniques and materials)...or just the ability to check prototypes initially for testing?
you should try 3d hubs, https://www.3dhubs.com/ it lists people with 3d printers that are local, I live out in the sticks a bit but there are still several printers just mins away from me, so you can remove the delivery charge and pick them up yourself, printers like the Formlabs can print at a higher res than Shapeways Ultra detail and you will find a lot of them on hubs, with much less markup.

I meanwhile always use overlapping geometry and had no problems so far. Wich materials do you mean wich could be a problem here?
I know 3dhubs and was considering to use it, but for some reason I decided not to try yet. It looks very promising, but it is not soo much cheaper depending on what you need and material. Have you ever tried 3d hubs?
