Shapeways community member Alec Cox designed his wedding ring in Blender and had it 3D printed in silver.
[Caitlin and I] went to the same high school but have gone to different colleges (she goes to MIT, I go to a school in Ohio) for undergraduate, so 3D printing has given me the ability to create our rings where distance has taken away the traditional ritual of shopping for rings together. While I initially tried to smelt the rings myself, this resulted in a pile of useless silver slag and a whole heap of danger concerning oxy-acetylene torches.
So, while I have no experience at all with smelting metal, I have a little experience with the 3D modeling program Blender. This let me add the amount of personalization to our rings that we wanted while keeping the price-point down (you know how crazy expensive wedding bands get). While I kept my wedding ring a simple toroid scaled in the z axis (with not that many faces), I added a ton of resolution to her ring so that I could use the sculpt tool in Blender to write a line from a Beatles song on the inside (a mutual love of the Beatles is part of the reason we started dating).
The quote in the ring is "Love you forever and forever" from the song "I Will."
