@Ratchett I signed up for shapeway's porcelain beta. Diswasher safe, micrwave save, high temps... what's not to like other than not having something that is clear?
Yeah, I want to get into Porcelain 3D printing, but I didn't want to attract unwanted attention from Shapeways regarding what I'm making in porcelain. The last thing I want is shapeways to shut down my store before I even got it off the ground!
The last I heard about 3D printed glass is that current glass 3D printers produce a fragile semi-translucent material.
I'm still not sure if Porcelain will work for my needs, since the process involves 3D printing a mold based on your model and filling the mold with liquid porcelain. But as soon as they take it out of beta, I'm going to be placing a bunch of orders for test parts to see how they can handle various shapes/designs.
