Gold 3D prints
Designers nowadays are getting more creative with the inclusion of gold into 3D printing service. Not only is it a great way to quickly produce prototypes but also it is very popular amongst jewellery designers and watchmakers.
In the earlier times only big 3D Printing companies with access to production machines and facilities and independent jewellery designers would be limited to making items by their hands and efforts. But it was difficult or nearly impossible for some craftsmen to achieve some typical shapes and textures.
With the help of 3D printing in India, the designers are less stressed. 3D printing online allows them to create a wider variety of models. Also on the brighter side 3D printing services make it easier and cheaper for the craftsman to produce and distribute their products professionally.
Process
FDM printers cannot be used for 3D printing online with real gold. Availability of filaments in the market such as PLA infused with gold colour or even blends of real gold then produce models that don’t really look golden or have the lustre of gold.
For printing gold via 3D printing manufacturers typically are offered two ways-
- Direct metal laser sintering
- Lost wax casting
In DMLS layers of powder are used along with lasers to solidify the model which is later extracted from the leftover powder. In this process the post processing method cleans the model and polishes it with a beautiful golden shine or lustre.
In lost wax casting the process starts by using a high-resolution 3D printer to create a wax model. Later it has a plaster poured over it to make a mould. As a result the wax is easily melted away. Post which gold is poured into the mould to create the final model. In this process too, the final product is polished after removal.

How can you achieve getting gold 3D prints?
Considering the fact that you will be using real gold, achieving gold 3D print online will be costly. The DMLS on the other hand are also not cheap and can range up to 150000 dollars. Additional care should be taken while operating online 3D printing india with gold as the Powder must be contained properly because it is hazardous if breathed in.
It is not readily possible for anyone to print in 18 karat gold in the comfort zone at home. Hence you will be inclined to get assistance with affordable 3D printing services available online. The only reason is for an average person printing gold is much more expensive in terms of cost and time. Hence Online 3D printing services can back you up.
3D printing services
One of the most popular Online 3D printing services available is Craft Cloud. All you need to do is upload your file and select the material you want. On the latter part it will exhibit a price comparison from the best 3D printing services out there.
These affordable 3D printing services may include companies like Materialise or Sculpteo.
However making a choice in selecting gold can be a task. There are six different varieties of gold available for example gold, white gold and rose gold. These are available in 14 carat and 18 carat properties.
Best 3D Printing Materials for Jewellery Designers: Gold, Silver, Brass, Bronze
While 3D printing service in India has touched most of the areas human beings can possibly think about, it has not yet made the same kind of impact in the jewellery industry. The reason is not the shortcoming of online 3D printing technology, but the delusion of people. Most of us have a wrong impression that 3D-printed jewellery is made of metallic plastic. What we don’t know is, 3D printing service for jewellery is done using real, solid materials traditional jewelry is made from. In fact, the choice of materials for 3D jewelry printing is huge. But if you ask for the best 3D printing materials to flaunt your style quotient, then gold, silver, brass, and bronze are the ones you should prefer.
3D PRINTING MATERIALS FOR JEWELRY
- GOLD
This yellow metal is the favourite choice of jewelry designers, jewellers, and consumers. To use it for online 3D printing India, a wax mold is created, using the traditional hand method and digital design. However, modern-day 3D-printed jewelry designers prefer the latter method.
In short, a 3D wax model is the first thing that is printed by a high-resolution 3D printer. This wax model is then sheathed in a substance that resembles plaster, which is called investment. The wax model and the investment both are heated afterward at a high temperature for making an impression.
This impression is next filled with liquid molten gold to create a jewelry item, which is cleaned and polished by hand after the printing process is complete. You can 3D print online gold jewelry in 14 and 18 karats. Moreover, there is a choice of yellow, red gold, and white colour finish.
- SILVER
The advantage of preferring silver for 3D printing is its durability and characteristic to be free of scratch, and wear. Moreover, there are also options to go for different finishes such as gloss, high-gloss, satin, rough, and mirror polish. To 3D print silver jewelry, a wax model is printed first by a 3D printer. This wax model is then used for creating a mold.
When the wax model is printed, it is then encased in a plaster-like material or container. This container is developed as such to allow draining of wax and pouring-in sterling steel from each hole. When the process is complete, high-quality 3D-printed silver jewelry is obtained.
- BRASS
If you prefer low-cost and customization for 3D printed jewelry, brass is one of the best options. 3D printed brass jewelry not only looks great but also costs less. Further, it requires low maintenance. When you have selected brass for jewelry, you will need a design. If you have it, upload your design to 3D printing companies for online 3D printing Your design will be wax-printed to create a model, which will be placed in a container that will then be filled with liquid plaster.
The wax will be heated in a furnace to melt and achieve a mold. This mold will then be filled with molten brass and exposed to high temperatures for making it hard. When the mold is hardened, it is broken to get the final product.
- BRONZE
This alloy, in which copper is the main element, is affordable and usually in reddish-yellow colour. If you prefer bronze for 3D printed jewelry, you have to go for PU coating as well since it is susceptible to scratch. With PU coating, you can polish the bronze model. As far as the online 3D printing process is concerned, there a few steps that are common with other 3D printing materials for jewelry. This means, a wax model is created first, which is then covered in a container with liquid plaster to form a mold. The mold is then poured with molten bronze and hardened. After which, it is broken to the final product is revealed.
Advantages of computer design.
3D design will facilitate and improve our work on a new collection or personalized jewelry. Making a full-size ring, rescaling the necklace on the earring, full control over the weight of the target product, the possibility of perfect stone arrangement – this is only the beginning of a long list of 3D advantages.
The 3D model allows us to prepare patterns with a high level of detail – often in a faster time than using a traditional workshop. Modeling in the program also eliminates the element of randomness (destruction of the wax mother by slipping a file or cutter) – and if something in the design does not suit us, it’s easy to go back to the previous version and expand it in another direction.
- 3D model
This is a file usually saved in .stl format – if you want to use the 3D printing service in India, you will need such a file. How to get it Preferably from a person providing 3D design and modeling services, who will make a model for you based on an interview or a drawing. It is worth making sure that we are not a layman here – this will avoid problems with the later incontinence of the size of the ring, too thin and non-castable elements or unmatched stones.
- Curiosity
Not everyone knows that .stl files are used not only for printing, but also for milling on CNC machines, which by cutting material layer by layer, will recreate the model in wood, aluminium or wax.
As we mentioned earlier, there is a lot of 3D printing online technology and each will work on slightly different types of projects. We would like to focus on those types of printing that are commonly used in the jewelry industry.
- Wax printing used by Solidscape printers.
This is the most popular 3D printing technology. Solidscape has in its offer printers using the SCP (Smooth Curvature Printing) method. Printing is done with the help of two materials: a supportive one that can be dissolved at the next stage and a second one that builds the right part of the model for us. The model we receive will be made of wax, which ensures perfect burning during casting and at the same time prevents the mold from being removed from the printout itself.
If we had to determine the undoubted advantage of this prototyping method, then there is no need to manually get rid of the printing support material (so-called support) and high printing accuracy. It is also an ideal technique if the pattern we make is to be used once (we do not expose ourselves to the costs associated with making the molds). The main downside of this method is time – which translates into price.
- Print in photosensitive polymer.
Another printing method is the one that uses polymer as the model building material. Depending on the manufacturer of the printer, it has different names (this involves branding the technology names with a trademark). The main rule is based on the SLA (StereoLithography Apparatus) method and consists in fixing the resin with a light beam.
ASIGA is a popular printer that uses various types of polymers for printing. Individual materials differ not only in colours, but also in properties. The great advantage of this technology is good quality and fast printing time. The downside may be the need to manually remove the supporting material – which in the absence of practice may damage the model. However, if the design is not complicated in 3D printing online, and there are few additional supports – this technology is a pretty good alternative to the Solidscape mentioned earlier. We are able to remove the form from polymer even in dedicated vulcanization rubbers. This material is rather not suitable for direct casting – the exception is a polymer specially created for this.

- Printing directly in metal.
The last and actually the least popular due to the relatively high costs is the direct metal printing method, i.e. (Direct Metal Laser Sintering). However, it has advantages that cannot be obtained by printing + casting techniques. We can print an object that will be empty inside; an object with moving elements contained in one another; items that are too small to be cast by lost wax. With the help of this technology, we can print in gold, silver, titanium and platinum.
Gold 3D printing process of creation:
- first, the model is printed in SLA technology (stereolithography) from wax, in the form of a properly prepared resin; stereolithography ensures high quality of the model
- then the printed model is put into a container where it is poured with plaster in a suitable way, creating a mold for casting
- the mold is heated, as a result of which the wax dissolves, leaving the walls of the model perfectly in plaster
- molten metal is poured into the mold, which then cools down
- at the end the form is broken up and the newly created model is subject to subsequent production stages in the form of a suitable finish.
Machine vs Man.
3D printing in India is a tool that is designed to improve our work, save time and help in the implementation of projects that would be impossible to perform or highly unprofitable in the case of, for example, manual carving in wax. Contrary to the opinions of people who have nothing to do with new technologies, the computer does not carry out the design for the designer.
The 3D program is a set of functions whose skilful use will be associated with a specific effect. Just like using the same stylus – two people will do work at a different level, so with the same modeling program, two designers will get a completely different effect. Let us remember that in all of these, man is the most important thing – not a machine.
