We recently prototyped some of our most popular 3d-printed jewelry designs in gold-plated brass. These are produced in the same way as our sterling silver designs. First, they are 3d-printed in wax at a high resolution. Then, they are cast in brass using the lost wax method. Finally, they are polished and plated with 22kt gold. We are not sure if we are going to add this material to our collection. But, the limited stock we have available is currently for sale in the Nervous System Etsy Shop. You can see the pieces we have available below.
