A Guinness World Record Diamond Ring Made With 3D Printing

Imaginarium, a 3D printing service based in India, broke a surprising record last year when it contributed to the creation of the ring with the most diamonds in the world: 7,801 to be exact. This record was entered in the Guinness World Records last September and was made possible thanks to additive manufacturing. Named The Divine – 7801 Brahma Vajra Kamalam, the ring was modeled using computer-aided design (CAD) and its mold was 3D printed using direct castable resin before being cast in gold. A long-term job that started in September 2018.

In the jewelry sector, more and more players are turning to 3D printing to create more complex custom molds. The goal is to 3D print the model of the jewelry with wax. It is then wrapped in a refractory material, thus making it possible to obtain a mold. The wax inside is then heated to create a vacuum inside the mold, which will be filled with molten metal – gold, silver, bronze. The mold is then broken to obtain the final product. Thanks to additive manufacturing, jewelers can imagine and create more original models, which would be impossible to obtain via conventional manufacturing processes.

This is surely what motivated Kotti Srikanth, manager of Diamond Store by Chandubhai, to use the Imaginarium printing service. His goal was to design a ring with as many diamonds as possible, which involved knowing exactly where each would be placed. After imagining several iterations, the designers of the ring explain that they ultimately opted for a flower shape, more specifically a Himalayan camellia flower. This would offer a perfect balance between traditional and more modern forms.
