Speed, precision, simplicity and the ability to make customized items. These are the main advantages of 3D printing, the technology that has changed the production process of many jewelry companies, big and small, especially in the prototyping phase.
The human component is fundamental both in the phase of creation of jewel and in prototyping. However, 3D printing saves time and increases accuracy. Once the design has been produced with CAD Software, we proceed to wax prototyping; after that we recover the classic production chain, casting the final item and finishing it afterwards.
