Traditional jewelry design is a meticulous and incremental process. Because labor and materials are a large investment for both the jeweler and the customer, confidence is the baseline requirement for both sides of a commission. Once the sketch is approved, it is carved out of wax and re-inspected before casting. Either way, a large amount of time is put into this process, which typically spans anywhere from two to three weeks.
The MJP 3D printer produces micro-detail wax patterns with outstanding surface quality and extremely fine features, ideal for intricate direct investment casting applications, such as jewelry. Uptown Diamond decided to incorporate 3D printing into its workflow because the company wanted to both speed up its manufacturing process and ensure a quality product. Cost cutting was also a large consideration. For general wax casting, Uptown Diamond was familiar with CNC machines, but the time involved was still considerable, requiring four to five hours per machining.
With its ProJet, Uptown Diamond is able to simultaneously print as many as 50 unique wax designs that are ready for casting in 10 hours. Alternatively, the company can print a single wax pattern in just two hours, which means that it now has the capability to cut and cast waxes for its customers in the same day.
We never have to say no anymore. Because there are no limitations to possible geometries, 3D printing has enabled creative experimentation in design. Uptown Diamond has had the opportunity to take on immensely intricate and personalized projects, including an engagement ring mimicking R2D2 for a pair of Star Wars lovers designed by Uptown Diamond President Grayland Noah.Anycubic Castable Resin REVIEW - casting bronze rings, coins and more
Before getting its machine, Rick says Uptown Diamond was on the same level as its competition with championship rings and faced the same hurdles of presentation artwork and the high cost of molds. Uptown Diamond invites its customers into its workshop to watch the 3D printer at work. They really get to design their own jewelry and see the whole process. Rick is now thinking about getting a second 3D printer just to keep up with the demand.

Using this extruder anyone can create temporary disposable objects out of beeswax. The wax needs to be melted at 60 degrees and hardens once is has been 3D printed into an object.
In this case the extruder is not only a tool for Joris and myself to complete this project but others can use it as well or build a better version of our extruder. Open Source gives you the ability to share both your designs and the tools that let you make them. As a designer I feel a real creeping unease about my vocation.
Creating, crafting and manufacturing objects that work brings me immense joy. There is next to nothing in life as satisfying as making a resolved, working, beautiful and useful thing. But, at the same time factories spit out millions of things bad and good and these things are used for ever shorter time spans and then buried in landfill. I know of many designers that feel the same design angst about being a designer in a mass manufactured age. This is the spark that lead me to the 3D printed beeswax project.
If the world wants temporary things and wants to consume things at higher rates then lets create a way to out of beeswax. Give this world the temporary things it needs through a sustainable process.

Its defining property is how changeable it is, never quite hardening to settle into a definite shape, always moldable at the slightest push of a finger. But, when we learned that you could, in fact, get great 3D printed objects from wax material and filament, we were very pleasantly surprised, even more so when we saw how easy it is if you have the right equipment.
In chemistry, the wax is defined as a simple lipid made from long-chain alcohols and fatty acids combining together. There is a variety of specific types of waxes found in nature, the most common being the type that bees secrete. Because its physical properties can shift more easily than materials rooted in firmer molecule bonds, you have to consider several general factors no matter which process you choose as your wax 3D printing preference.
Wax is most commonly used to create molds because of its stellar layer resolution of 0. And when used as molds for intricate yet delicate products like printed jewelrythe metal that fills the mold takes all that detail with it to the final product, something you could never achieve with the lower layer resolution of pretty much every other 3D printing material.
They do this by printing the wax at two different temperatures; the wax that melts at the higher temperature, about 70 degrees Celsius, is used for the object itself, and the wax that melts at a lower temperature creates the supportive material that bridges gaps in the wax patterns until the initial wax hardens.
Then the supportive wax is melted off. Wax generally has a lower melting point than most other 3D printing materials. This makes it easier to use as a mold and supporting material, of course, since you can melt them off whatever they are upholding without worrying about melting the actual molded object itself.
In nature, the wax is often excreted by leaves and other parts of plants to keep them from absorbing too much water in rainy areas of the world. The biggest drawback of working with wax to make any sort of solid final object is that you will not be able to use untreated wax on its own without putting your object in major danger of destruction. Even with the assistance of finishing details such as these, the wax is difficult to use as material for a final product. But this is worth mentioning as an extra burden on whoever is looking to 3D print with it.
Wax needs an additive process that will deposit it onto the printing bed, and both inkjet and drop on demand equipment can do that for you. Is this absolutely necessary to process 3D printing with wax? Is this the part of the 3D printing process that is most likely to turn into a science fiction movie starring Tom Cruise? You bet! Although you can 3D print wax objects to be their own thing, 3D printing with wax goes to the next level when you use it to create molds for other materials.
We strongly recommend trying this method if you work with small to medium objects in materials that are difficult to detail on their own, like precious metals.

The wax printing process is a type of stereolithography that uses a wax-like resin. These support structures are automatically generated and manually removed after the printing process.
After support structures are removed and your model is cleaned, the model can be prepared for casting. First, one or more wax sprues will be attached to your model. The tree is then placed in a flask and covered in a fine plaster. When the plaster solidifies, it forms the mold for casting the metal.
The plaster mold is then put in an oven and heated for several hours to a point where the wax is completely burned out. Then, the molten metal is poured in to fill the cavities left by the wax.
Once the metal has cooled and solidified, the plaster mold is broken and the metal models are removed by hand. Finally, your model is filed and sanded to get rid of the sprues. It will be sanded, polished or sandblasted for the finish you desire. Seems your browser is blocking cookies. Please adjust your settings to accept cookies.

In general, 3D printing technologies can be split up into 2 groups: direct and indirect 3D printing. The main difference lies in the fact that the design is made from 3D printing direct or 3D printing was used in the process of creating your model indirect.

Lost Wax Printing & Casting
Please check your inbox to confirm subscription. Get Social with Us.Most 3D printing technologies are direct; they directly create the finished object with no casting or further steps needed. These include Fused Deposition ModelingStereolithographyand many more.
However, one lesser-known technique which 3D printing is also useful in is Lost Wax Casting, an indirect 3D printing process. Also known as investment casting or precision casting, Lost Wax Casting involves creating a duplicate, or clone, of an original mold; usually from a metal such as gold or silver.
The process has a rich history; it is believed to have been used since between BC and BC, with objects found in southern Israel created using Lost Wax Casting dated back to BC.
We also have a free 3D printing ebook featuring guides to all the main 3D printing technologies. Click here for more information. This is because you will need to design the 3D printer model which you intend to create to 3D print the original mold. Simply create your chosen piece, whether it be a piece of 3D printed jewelry like a ring or pendant, or even a crazy 3D printed heart.
There are a number of good wax filaments which are compatible, though the Pro Jet range is able to print supports in material that has a lower melting point, making the support removal process simpler.
3D Print Patterns For Investment Casting
Stereolithography printers like the Form 3 naturally print in a wax-like resin, similar in consistency to the waxy texture required. Once your original, 3D printed mold is ready, you need to create a sealed area, or sprue, where you can pour the material inside.
Once this has dried, remove the model. This is an exact negative of your original, 3D printed mold, and will form the basis of what will create your metal 3D printed piece.
How To Find The Best Wax 3D Printer 
Once your chosen metal has been heated to a high enough temperature and melted, pour it into your negative mold. This make a few tries to get right, and if not done properly can leave you without good enough detailing on your model. This cut will be rough, and will require polishing, sanding, or a similar process.
Anything else beyond this is completely your choice.
You may wish to accessorize your piece with extras that match your style and creativity. A variety of metals can be used in Lost Wax Casting rings, pendants, and more. However, since the uses are mainly jewelry, more precious and expensive metals are used most commonly. These include:. Unsurprisingly, given that Lost Wax Casting excels at creating very precise geometric patterns of metals, the process is used extensively in jewelry.
Pro Jet 3D printers are accurate up to 0. The jewelry can be created to perfectly set jewels like diamonds, emeralds, and rubies, making it a versatile and very attractive option for jewelers. Your email address will not be published.

Additive manufacturing offers the possibility to 3D print using a wide range of materials from plastic to resin and metal. But what about wax 3D printing?
There are actually different ways to print wax. We are going to tell you about 3D printed wax processes and applications. Here is everything you need to know about wax 3D printing! The casting process mainly allows to produce customizable jewelry of very high quality and 3D design complexity in various printing materials, such as metals.
The cast process mainly allows to produce customizable jewelry of very high quality and 3D design complexity in various printer materials, such as metals. The idea is to create concept models with 3D modeling and then 3D Print wax patterns of the desired object thanks to a wax 3D printer. Then, by adding a refractory material around this model we obtain a mold. Melting the wax filament inside the mold creates an empty space that is filled with the 3D printers material, molten metal.
The only remaining step is to break the mold to obtain the final object. Variable finishing options for this 3D printing technology are then available. In addition to the lost-wax casting process, it is possible to actually 3D print wax. The material often used to print wax is not real natural wax, but it is a wax-like material, the mechanical properties of this material are then similar to wax. Unlike filament printing technique, multi jet modeling process MJM looks a lot like ink jet technology.
Molten wax filament is deposited by nozzles on an aluminum build platform that moves down, layer by layer. This support wax enables the creation of almost any form, even the most complex product designs and the most complicated wax patterns. During this printing process, the wax is deposited in dots instead of a continuous line as we can see with technologies such as inkjet 3D printing.
This will also depend on the 3D printing wax process you will use. Moreover, using wax for casting process will allow you to get really detailed molds for products with an intricate geometry. Wax printing is mainly used to create dental molds and 3D printing jewelry. As a 3D printing service, we offer you a lot of different materials, technologies, and finishes to give life to all your projects. Among all of these possibilities we are offering you, you can choose to try lost-wax casting to start your jewelry business.
Indeed, affording your own wax 3D printer might not be the most coherent and cheapest choice to develop your use of wax printing. Moreover, printing this material is a little bit more complicated to operate. You can visit these material pages to see how you can use properly brass or silver as 3D printing material, to consult the safety data sheets and white paper for proper design guidelines, and to find their shipping info.

This product can also be polished, machined, and carved MUCH easier than plastic filaments. Print2Cast is softer than traditional plastic filaments.
3D Printed Beeswax
Because of this, some extruder feed drives may need to be modified in order to properly feed the filament. The easiest way to determine if your printer will need any modification is to find out if other people are already using any of the flexible filaments on your machine. Many of the rubbery, flexible filaments on the market are even softer and more flexible than Print2Cast filament. Because of this the modifications necessary for them also work well for Print2Cast filament.
There are two key points to keep in mind when printing softer filament material. Provide proper tension on the guide arm bearings that presses the filament into the drive gear to prevent grinding. For bed adhesion, our personal experience has had the best results using multiple layers of "extra super hold" hair spray on a heated glass bed.
We recommend spraying the glass with 6 light coats, letting them dry in between coats. A second option for bed adhesion would be to use cloth athletic tape or gaffers tape.
Here are a few startup recommendations to help get you started. Please keep in mind that these suggestions can be dependent on both your printer design and the geometry of the object you are printing. Prints best when layers have enough time to cool. This can be achieved in several ways. A caution here is to not cool too fast. This will cause exaggerated warp.
Since we cannot collect this tax for you at our end when we ship by postal service, we will refund the tax to you and you can handle it at your end.
TPU or flexible filament is softer and more flexible than Print2Cast. So, if the feed drive can reliably feed TPU, it will generally handle the wax reliably as well. The stock firmware on some machines will have a cold extrusion limit that has plastic in mind and will prevent the extruder from running if the detected temperature is below a certain limit regardless of the temperature selected in the slicer.
Quite often this can be bypassed with an M code being added to the start sequence. Though, it is best to ask the printer manufacturer about the ability to print at lower temperatures if you are not certain. Some other features that are more ideal for wax would be a direct drive extruder, an all-metal hot end, a heated print bed, and an enclosure. Bowden and open frame machines can still be viable, but not as ideal. The feed drive is less of an issue with 3mm filament because of the extra rigidity the larger diameter offers.
An enclosure can also be built fairly easily, so I wouldn't let that be a deal breaker if you find a printer that fits your budget and other parameters.
The first thing to address is the term melt out. This can work for some basic mold geometry like a cone or sphere where gravity can allow the wax to escape, but overall we recommend a true burnout procedure over melt out.
Best practice for this is to follow the instructions of the investment manufacturer you are using above all else. For the DIY crowd using homemade investment options plaster and sand mixes are commonwe recommend a hour schedule for most mold sizes with a slow ramp up to peak temperature. This will allow the wax to slowly melt out much of the cavity leaving the mold with plenty of space to handle the natural expansion of heating the wax.
Higher peak temps will ensure complete burnout. The homemade mixes will start to degrade at these temps so some testing should be done to see what your specific mix will handle as there is no one size fits all number. A kiln is most ideal to accurately reach and maintain temperature for DIY or professional grade casting investment. DIY kilns can be built as another option.
