Printing with Metals, Plastics, and Castable Resins

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.

5 Best 3D Printers For Jewelry 2022 (All Price Ranges!)

3D printing jewelry rarely means 3D printing actual wearable pieces made from filament or resin, but instead using a jewelry 3D printer to create high-resolution wax models of the eventual gold or platinum design, used to create a mold that is burned out and cast via investment casting or lost wax casting.

We also have an article ranking some of the most beautiful 3D printed jewelry.

In fact, much jewelry is now created this way. There are entire factories of resin 3D printers set up to create castable wax resin models to be molded and then melted to create high-end jewelry.

However, owning your own jewelry 3D printer gives you more control over your production, and saves you money compared with paying someone to print your own molds. Castable resin molds can be produced for rings and other jewelry pieces for just the cost of the resin used, perhaps a dollar or two, whereas you could end up paying $25+ for someone to print it for you.

The Jewelry 3D Printing Process

CAD File: Either design your own jewelry piece on CAD software, pay someone to design your desired piece, or pay for an existing jewelry STL file online and download it.
Slice & Prepare: If not already an STL or other compatible file, export it as one. Then import it into your 3D slicer and slice it for printing.
Print the model: Use a castable wax resin designed for jewelry model 3D printing.
Molding: Pour your molding material over your wax jewelry model, and leave it to harden.
Melt the wax: Heat your new mold so that the original wax model melts and evaporates, leaving a hollow empty space inside with the exact dimensions of your planned jewelry piece.
Casting: Pour melted liquid metal e.g. gold, silver or platinum into the mold to cast it.

What are 3D printers for jewelry?

Resin 3D printers are considered the best 3D printers for jewelry. They are used with specialized castable wax resins, which rather than going from solid to liquid when heated, transition directly into a gas from their solid state.

Though prevalent, FDM 3D printers are very rarely used as 3D printers for jewelry. They are not capable of the same resolutions, crisp surface finishes or accuracies required for intricate and delicate jewelry pieces. Jewelry 3D prints need to be incredibly highly detailed and accurate — an inaccurate mold will create inaccurate and unimpressive jewelry.

Additionally, the better the jewelry 3D printer quality, the less finishing the resulting jewelry piece will need to perfect it.

What do jewelry 3D printers make?

Usually they 3D print wax jewelry molds, for example of ring designs before any stones are set, or individual chain links.

However, they can also be used to create like-for-like “fitting pieces” for testing the fit of an as-yet unmade ring for a client’s finger. Though making the final ring would be expensive and take time, an exact replica can be made on a jewelry 3D printer in just minutes to test the sizing.

This saves the trouble of creating a piece just to find it doesn’t fit properly. Whereas for jewelry molds specialized castable resins are required, for these fitting pieces standard resins can be used.

Choice of technology and 3D printer for jewelry making, pros and cons

Currently, there are many new technologies that are designed to simplify production in various industries. Progress does not stand still and, despite some opponents, 3D printing has its own niche in the production of jewelry.

3D printing can speed up and reduce the cost of jewelry production due to the low cost of consumables. With 3D printers, jewelers have the ability to quickly change the design of a product and make prototypes at least several times a day. For many jewelry industries, 3D printing is becoming a good alternative or addition to milling machines and other equipment. nine0003

Until now, some believe that handmade is a sign of craftsmanship, especially when it comes to creative work, and models made using 3D modeling and printing are amateurish. But many people forget that behind the computer is the same person who not only mechanically presses the buttons, but also puts his soul into his creation.

Benefits of 3D printing

In order to understand how justified the use of a 3D printer is, you need to know how jewelry is made. This is very painstaking work. No wonder the expression "jewelry work" appeared, denoting a very delicate and complex work. nine0003

Any decoration begins with a sketch. Usually several sketches are made in order to accurately determine the design and location of the inserts. Not only stones are used as decor, it can be elements made of wood, bone, precious metals, it all depends on the designer's imagination.

At the next stage, the product is drawn in a 3D editor. This allows not only to visualize the future product, but also to correct some errors and inaccuracies made at the design stage. nine0003

Ring model

Some craftsmen still carve "stencils" by hand. Such work requires certain skills and perseverance. Usually this is how products are made that will be cast in a single copy.

A finished 3D model can have several ways to be implemented in a physical version - this is milling or 3D printing.

Stencil milling

Currently, 3D printing is not much inferior in accuracy to a milling machine and often has a significant advantage in speed, despite the fact that after printing it is still necessary to separate the supports and clean up the points of contact with the model. Once a physical model has been obtained, it can be cast immediately if the material used is wax or a burnable polymer.

If it is necessary to cast a large batch of products, then a mold is made from the master model made with the help of special rubber for subsequent wax casting. There are many types of rubber that vary in hardness and curing temperature. Rubber is selected depending on the material from which the master model is made. nine0003

For pouring molds, a special machine is usually used - an injector. In some models, you can not only heat the wax, but also vacuum it or leave it under pressure. This helps to reduce the number and size of air bubbles for better pouring of the rubber mold.

In home workshops, silicone is used instead of special rubber. After all, a special machine is needed to vulcanize rubber. But rubber molds are too soft and short-lived for making a large batch of stencils. nine0003

After making the required number of stencils, they are collected in "Christmas trees". "Elks" are waxes soldered to a wax rod. To save space, the distance between them is very small and they resemble fluffy Christmas trees, hence the name. The finished Christmas tree is weighed to calculate the required amount of metal. In some places, stones are immediately inserted into the stencils, unless another mounting option is provided.

nine0003

Stencil Christmas trees

Ready "Christmas trees" are placed in a special cylindrical "cassette" without a bottom, which is called a flask, and filled with a gypsum-based molding mass. The flask with uncured gypsum must be evacuated to get rid of unnecessary air bubbles that can lead to defects on the surface of the finished casting.

After hardening, the gypsum flask is sent to a muffle furnace to melt the wax. nine0003

The calcination mode is selected depending on the material of the wax. For wax or burnout polymer, different modes are needed in order for the material to be completely removed from the gypsum!!!!!!

When all the wax is melted, cavities are formed inside the gypsum, repeating the contours of the wax. Metal is poured into these voids. After casting, the flask is cooled and the gypsum mold mass is washed out under the pressure of water. The result is a metal Christmas tree. nine0003

Herringbone after casting

Finished castings are cut from the Christmas tree and washed, polished, if necessary, blackened by the master until the desired appearance is achieved.

3D printers for jewelers

There are several 3D printing technologies that may be suitable for the needs of jewelers. Each has its pros and cons. Some 3D printers are ideal for a large workshop, and some are ideal for a small workshop. nine0003

SLA

SLA or stereolithography is based on the principle of layer-by-layer solidification of a photopolymer resin under the action of a UV beam. The UV beam is focused by means of mirrors on the surface of the resin and illuminates the model in layers.

How the SLA Printer Works

SLA 3D printers were the first to be noticed by jewelers. SLA devices are compact, while they have high printing accuracy. nine0003

DLP/LCD

DLP is very similar to SLA, only as a source of UV radiation, to illuminate the photopolymer resin, not a directed beam of light is used, but a DLP projector. DLP printers illuminate the entire work area at once, so they greatly outperform SLA in print speed.

How a DLP Printer Works

Today it is one of the most affordable photopolymer 3D printing technologies. In terms of cost, LCD printers have caught up with the price level of amateur FDM. DLP printers are much more expensive due to the use of an expensive projector as a UV source. nine0003

The projector is of course more expensive, but more durable, on the other hand, the LCD display is not so expensive and can be easily seen, unlike the projector. What to choose each user decides for himself.

MJM/MJP

MJM (or similar PolyJet technology) is a technology for layering photopolymer or wax through many fine nozzles. Typically, the print head is located from 96 to 448, depending on the printer model.

If a photopolymer is used as a material, it is immediately cured by a UV lamp, which is located on the printer's head. nine0003

How the MJM printer works

In addition to photopolymer, MJM 3D printers can use wax as a material for printing.

MJM printers can print multiple materials at the same time. This allows you to print complex models with soluble or investment supports. This makes it possible to produce complex models with a smooth surface quickly and easily.

Pros and cons

pros

Ability to print multiple materials at the same time. This means that another, soluble material can be used as a support. This allows you to save a lot of time on removing the support from the finished model and cleaning up the places where the supports come into contact with the print.

Minuses

To install the printer, most likely, you will need a separate room. 3D printers based on MJM technology are quite bulky in their dimensions, this is not a device that can simply be placed on a desktop or nightstand. nine0003

Totals

Photopolymer 3D printers are no longer inferior in detail to professional milling machines. The main advantage of a 3D printer is the ability to produce models of complex geometry with many internal cavities that are physically impossible to produce on a router. nine0003

Large firms will appreciate the flexibility that allows them to quickly adapt to customer requirements, as well as quickly produce large and small batches of products due to the shortening of the production chain.

And for a small workshop, a small photopolymer printer with a can of burn-out resin can be a good help, eliminating the need to purchase some expensive machines.

Jewelry - 3D printing of master models for direct casting

3D modeling and printing technologies have revolutionized the jewelry industry. The fact is that in this area a lot depends not only on talent, but also on the precise work of the hands. And this work is truly "jewelry". It requires a lot of attention, concentration and time, it is also difficult to eliminate human errors (jewelry).

3D printing has improved the process of making jewelry and souvenirs. Products are fully modeled on a computer, and then sent to print in a 3D printer. And neither hand can compare with this tandem in terms of accuracy and perfection. It is possible to create even the most complex products in terms of geometry and execution, including completely miniature ones. With the use of printing, the manufacture of jewelry can be carried out by two methods. The choice depends on which batch of products you need. Various approaches are used to reduce the cost of one product. nine0003

Our company is professional in 3D printing. We provide 3D printing services in the jewelry field due to the availability of specialized high-quality equipment, which is characterized by the highest accuracy. This allows us to quickly carry out 3D printing at affordable prices.

If the product will be a piece, then you can use individual models, burned out during direct casting. At the same time, based on the STL file, which contains information about the modeled product, 3D printing is carried out. A special wax or photopolymer can be used. Products do not require additional processing, as they are distinguished by high precision and an ideal surface. In the future, each individual product is fixed on the leg and a so-called "tree" is created. This tree is placed in a capsule filled with a special material. The capsule is placed in an oven where the material is cured and the models are fired without ash. Then molten gold, silver or other metal is poured into the resulting mold. After cooling, finished jewelry is obtained. This approach is optimal when creating piece jewelry or a small batch. nine0003

In our company you can order high-quality 3D printing of individual models of jewelry for direct casting.
