3D Printed Jewelry Molds

Time and cost savings for makers and artists.  

I was able to use my desktop 3D printer to manufacture prototypes, casings, and molds, which were later used for casting my unique silver jewelry.

Paula Szarejko

Challenge

In order to create something unique, Paula Szarejko decided to combine traditional jewelry making with her desktop 3D printer. Using her own machine instead of an industrial printer or outsourcing services, allowed her to quicken the process and lower its costs. 3D ornaments designed by Paula included two pairs of earrings (geometric icicles and low poly wolf heads), three rings (with zirconia stones, with a silver bow, and with a geometrical shape), and a low poly wolf head pendant.

Solution

First, she 3D printed all of her designs with an ABS filament and fabricated forms about 5 x 5 x 4 cm each. She then flooded her prototypes in forms with two-component rubber. After about 20 hours, she opened the form, cut the rubber mold in two, extracted her objects, and took the molds to a professional jeweler. The caster injected them with wax and used the wax models to make a jewelry tree. Dipped into plaster, it became a casting mold after reducing the wax in high temperature. Jeweler then poured 45 g of silver into the mold to create the raw objects.  

Result

Objects cast from metal always require post-production. Regular files and sandpaper were enough to grind bubbles and clean them. Paula polished a very clean surface on the geometrically shaped ring but left visible 3D printing layers on the icicles earrings. The results are simply gorgeous! Packed in custom-made boxes the entire collection of jewelry have this unique feel and can make for a very chic and memorable gift, while the entire costs closed at 150$. These fabrication methods can be used for casting objects from various metals and other materials too.
