When i put in my 3D image of a ring it tells me the price in 14k gold will be $1396.22. Is there any way to tell what the weight will be ? I have attached the file, if any one can help me that would be great. Thanks.

Density of 14k gold varies between about 13 and 14g/ccm (or over 15 for modern "white" that has palladium instead of nickel) depending on what the non-gold elements in the specific alloy are (see bottom of materials page for alloy compositions used). You can find the volume of your model on its shapeways page if your software does not show it - going by the price you mentioned it appears to be about 2.2 ccm, or about 30 grams of their "14k yellow gold" (density around 13.3 if my quick calculation is correct - you will find 13.6 quoted for an alloy with equal amounts of copper and silver, but shapeways' has more copper)

Hi,

I wonder if it will print correctly in steel. I'm afraid that it won't pass sandcastle test.

It will not print.

Even if it did magically come into existence it would be extremely fragile and prone to bending or breaking.
