If you plan to work with a local jeweler who has a an accurate 3D printer, ordering a design only is a valid option. Most jewelers have the skill to finish a ring that is already designed and printed. Producing the printable file is the major hurdle. With this service you will receive not only the picture but also the printable 3D file in stl format.
This service includes design. You will get a rendered image of what your ring would look like and you can either request changes or approve it for production. I send regular updates as the project is progressing so at each stage, you will have a chance to see what the progress is like before I move onto the next stage. This way there are not surprises as to what the final product would look like. I always follow customers’ instructions. After all, this is your project and it should turn out the way you envisioned it. If however you are somewhat flexible with the original idea that would demand higher budget, small changes in the design or choice of materials will in most cases, allow the project to fit in a pre-determined realistic budget. Most people do not realize that requesting a customized item means bearing the full cost of production from scratch. The concept is similar to ordering a car from Toyota made to your specs vs buying a standard Civic model. On average your custom specs will imply a 10 times higher price. For items made out of more valuable materials, the difference is not that drastic.
