Jewelry, an ancient craft, is increasingly turning to the modern technology of 3D printing to improve jewels conception and production processes. The top applications of 3D printing for jewelry are in prototyping and direct manufacturing of jewelry.
- Prototyping. Professionals in the jewelry sector can save time and money by using 3D printing to make cost-effective plastic prototypes of jewelry pieces before sending the final design for production.
- Making patterns for casting. 3D printing can also be used in the manufacturing process of jewels to make patterns for investment casting.
- Direct manufacturing. It is possible to resort to 3D printing to make actual jewels using metal 3D printers. As metal 3D printing is still an expensive technology (metal 3D printers are quite costly!), users often send their 3D designs to 3D printing services such as Shapeways or Sculpteo, who offer a wide range of 3D printing materials including several precious metals such as silver, gold or platinum.
The main technologies used for 3D printing in jewelry are SLA or DLP. These resin-based 3D printing technologies allow to 3D print objects with a very smooth surface and a high-level of details, two requirements for jewelry 3D printing.

Many 3D designs directories offer 3D designs of jewelry ready-to-print on a desktop 3D printer. Of course, you will be limited by the type of material your 3D printer can use, either plastic-based filament for FFF 3D printers, or resins for SLA 3D printers. But with exotic 3D filaments, it is now possible to print “metal-like” objects using a regular desktop 3D printer.

What are the benefits of 3D printing for jewelry?
- Cost-effective. It can be cheaper to produce a prototype of jewel using 3D printing than a traditional fabrication technique or tool, such as CNC cutting.
- Fast. Using a fast prototyping or manufacturing process such as 3D printing can significantly reduce the product design and production cycle.
- No limitations on 3D designs. 3D printing allows to make complex shapes and intricate designs which would be impossible to achieve with traditional prototyping/production techniques. This aspect is important in a creative field such as jewelry.
3D printing jewelry for professionals
3D printing offers several advantages for professional jewelry design and production.
3D printing for casting metal jewels
A very efficient technique to make jewelry relies on the fabrication of molds. Lost cast molding is a popular technique for directly producing metal jewels from 3D printed models. In this case, a 3D printed model of the piece of jewelry is first made of thermoplastic wax. Then, a mold (also called investment) is created around the 3D printed jewel. The investment is heated until the thermoplastic wax consumes. You can find more information about 3D printing for professionals jewelers in this Quora thread.
From there, the liquid metal (gold, platinum or silver) is then poured into this digitally designed mold. Once it’s cooled, the jeweler can add gemstones.
Stereolithography (SLA) is very efficient with a high degree of precision and compatible with specific resins.

Metal 3D printing for jewelry
3D printing makes it possible to manufacture small, complex, metal parts at high quality and speed. One popular technology for jewelry is Direct Metal Printing (DMP). The compatible materials are standard metal alloys and ceramics.
In this case, it is also possible to work directly with precious metals and make custom jewels on demand, without any stock. The parts do, however, usually require some manual finishing for a perfect look.
The best 3D printers for jewelry
The best 3D printers for jewelry are based on the SLA and DLP 3D printing technologies which use liquid resin as printing material.
3D printing technologies for jewelry: SLA and DLP
Most often, the 3D printing technologies used in jewelry applications are resin-based 3D printing technologies: mainly SLA (stereolithography) or DLP (Digital Light Processing). The best 3D printers for jewelry use the SLA and DLP technologies because resin 3D printing can produce higher quality prints and smoother print surfaces than extrusion (FFF) 3D printers, which use plastic filament as printing material.
3D printing resolution is critical in jewelry applications because the final products, jewels, are often tiny objects with a high level of details. Smooth surfaces are also required when using 3D printing to create molds for investment casting for example.
Jewelry 3D printers prices
There are several 3D printer brands specializing in jewelry applications. The prices start from a few thousands USD for entry-level desktop 3D printers using resin technologies. For more advanced 3D printers specifically designed for jewelry applications, prices can go much higher based on a variety of criteria, from print resolution to build volume, print speed and more.

3D scanning for jewelry
3D scanning jewelry gives you many advantages. This process allows you to get a detailed CAD file of a piece of jewelry, and capture a high-level of details.
Benefits of 3D scanning for jewelry
3D scanning brings a lot of improvements to the existing jewelry making processes, as it is a fast, very accurate and cost-effective method to capture in details pieces of jewelry. There are many benefits to 3D scanning jewels. Here are some concrete examples of applications and benefits of 3D scanning for the jewelry sector:
- 3D scanning a piece of jewelry to obtain a detailed CAD file of the piece. This 3D file is much more accurate than a picture, as every single detail and shape will be captured by the 3D scanner. Storing such digital files for later use (showcasing, archiving, modifying designs etc) is then easy.
- Creating a new design based on an existing jewelry piece. You just need to 3D scan the original model and make your modifications in the CAD software. You can then 3D print the model to build a mold for your new designs for example.
- Capturing a high-level of details, more than any bare eye observation could. 3D scanning a jewel allows you to easily identify any defaults or design flaws.

Case studies : when famous jewelers use 3D printing in design and production
Boltenstern jewel realized with 3D printing for jewelry (Source : boltenstern.com).
Marie Boltenstern, daughter of the owner of the Boltenstern jewelry in Vienna in Austria, decided to use 3D printing to create unique pieces. The “Resonance” collection is designed to fit perfectly the part of the body they’re worn on. Like fish or snake scales, these 3D printed pieces of jewelry are made of tens of small 3D printed scales attached together to move fluidly around the body.
To build these scales or tiles, she used a metal 3D printer.
Creating this unique piece of jewelry by hand with such intricate patterns would have been highly time-consuming and much more expensive.
It is important to keep in mind that 3D printing is not meant to replace jewelers, rather it is a new tool allowing them to explore further in terms of creativity and improve the conception and production phases.
Another brand using 3D printing to push further their quest of the perfect jewels the famous brand Graff Diamonds. Their Head of Technology, Sam Sherry, says: “These machines go beyond what the human eye can see and what the human hand can do with a saw frame”.
For Graff Diamonds, it is essential that their workers are classically trained and use 3D printers as another tool to create more challenging and intricate shapes.
According to them, the best jewels they created using 3D printing can be found in the Snowfall Collection. The pieces were first printed in liquid resin using the SLA technology and then casted with fine gold.
The precision offered by 3D printing allowed Graff Diamonds to take their art and skills to the next step. And as Mr Graff, the company director, says “If you don’t move forward with technology, you’ll eventually be left behind”.
