3D Printing in Jewelry Production

Updated Jul 01, 2022 279104

Rapid development of additive manufacturing leads to considerable changes in a lot of industries. Some of them use 3D technologies at all the stages of production, starting with 3D scanning and then employing 3D printing for prototyping or end-use parts production. Jewelry is one of the fields where digital technologies have only started their expansion, often being a bridge to traditional methods.

Digital revolution in jewelry

The craft of jewelry is as old as time, and it has always involved a lot of skill and time spent on every single item creation. Besides, there are always limitations to human possibilities — however skillful a craftsman was, some most intricate design concepts could only exist in their imagination.

With 3D printing development, more and more people in the jewelry industry are discovering the opportunities it provides both from the artistic and business perspective.

The traditional method of jewelry manufacturing implies lost-wax casting. Casting patterns creation is an expensive and time-consuming part of the process, and this is where 3D printing can be of great help, becoming a bridge to conventional manufacturing. What’s so good about using digital technologies in such a traditional field? Let’s see.

Why 3D print jewelry

Complete design freedom

As mentioned, there are certain design limitations in traditional production of casting patterns that are made either by hand or using CNC machines. With digital design opportunities and 3D printers capable of reproducing the digital models with extreme precision and accuracy, it’s now possible to create wax casting patterns of any complexity. The use of 3D printing has brought up new standards in the art of jewelry, allowing for the designs that could have never been realized before.

Unlimited customization opportunities

Customization is of considerable importance in jewelry as customers often want to get one of a kind adornment. 3D printing provides vast opportunities for custom products, either created from scratch, or by adjusting the already existing design according to the customer’s wish. The customization process doesn’t require additional costs and takes considerably less time and effort than in traditional production, where any changes made upon the product jacked up the price.

Faster prototyping

With 3D printing, customers have a try-on option to make sure the model fits perfectly and completely meets all their needs, before the final part is made. Printed resin prototypes are affordable and quick to make, they feature high quality and precision and can give the true-to-life impression of the future model.

Lower cost

Batch-manufacturing in jewelry 3D printing allows reducing the production costs, as a whole run of wax patterns can be printed in one go, thus saving material and shortening the production time; you can also print different designs at a time. All this makes jewelry manufacturing more cost-effective than ever before.

3D Printing technologies in jewelry production

Basically, there are two ways of implementing additive manufacture into the jewelry business, namely direct and indirect 3D printing, the former being less common, at least for now.


Direct 3D printing

Direct 3D printing of jewelry implies using metal (SLM or DMLS-based) printers to build the final parts right from the digital models, created in CAD software. The parts can be printed with gold, silver, or platinum alloys or other metal powders. Such an approach completely excludes traditional techniques from the production cycle and turns it entirely digital.

Despite all the general advantages of 3D printing, discussed above, this particular method is not very popular as it is more expensive than investment casting, and the printed parts require significant post-processing. Besides, precious metals are very difficult to print as they are highly reflective and thermally conductive. So, there are few printers in the market that can work with them. Still, rapid progress in digital technologies can change the situation for the better.


Indirect 3D printing

In this method, 3D printing is used to optimize the traditional lost-wax casting process to speed up the production and make it more flexible and cost-effective.

The jewelry 3D printing process

  • First the design of the future piece is created using CAD software. The STL (or other compatible) file is imported to a 3D slicer and prepared for printing.
  • The model is printed using castable wax materials to make a wax casting pattern. At this stage you may want to print a try-on part first to ensure the fit and design are just right.
  • The liquid molding material is poured over the wax pattern and left to solidify. Thus a mold for the future part is created.
  • When the mold is hard, it is placed into a furnace to melt or burn out the wax pattern, forming a so-called negative mold.
  • The final casting material, which is usually melted gold, silver, brass, or other metal, is poured into the mold and left to cool and solidify.
  • The mold is removed and the final part is ready for post-processing.


What are 3D printers for jewelry?

For direct metal printing, SLM or DMLS printers are used. However, very few of them can work with precious metals alloys, so other metals, like steel or bronze, can also be used.

Some jewelers create their collections using SLS technology, printing unique modern jewelry pieces with nylon or polyamide.

3D printing of wax casting patterns requires exceptional precision and accuracy, as well as the use of appropriate wax-like materials that can be completely melted or burnt out afterwards. So, the best options possible here are resin or material jetting technologies.

Now let’s see which printer models are the most suitable for jewelry manufacturing.
