Pioneering with precious metal 3D printing technology

BOLTENSTERN is pioneering the use of direct precious metal 3D printing technology to shape the future of fine jewelry.

Using state-of-the-art technology enables us to innovate in fine jewelry craftsmanship. We can create pieces which can not be created by hand or any other technique. Each piece is designed and coded by our BOLTENSTERN design team on a computer and then produced inside a 3D printer.

The pieces are printed by applying a fine metal powder, layer-by-layer. The layers are melted together during the process using an extremely fine laser, meaning that the pieces are constructed from the bottom up. Once the piece has been produced by the printer, it is rough to touch. The pieces are then polished and finished to perfection by our in-house goldsmiths.

This complex process of direct precious metal 3D printing enables us to create exquisite fine jewelry pieces.


Unique algorithms — coded by hand

The intricacy of the jewelry pieces lies in the coding of our algorithms. We use mathematical calculations to create perfectly geometrical structures in a 3D interface on a computer. The code is then fed to the 3D printers to initiate the printing process. Our coding process can take anywhere from a couple of months to several years and is all conducted by our very own design team, led by our Founder, Marie Boltenstern.

The result of using groundbreaking technology and combining it with algorithms based on mathematics and architectural design are iconic pieces of fine jewelry
you simply won’t find anywhere else.
