Is 3D Printing with Silicone possible? – Beamler
One of the greatest breakthroughs in the field of 3D printing materials in recent years was the launch of a process that makes 3D printing with silicone possible. Learn more about this exciting development.
Throughout history, inventions and breakthroughs in the field of material science have influenced the development of societies. And it is not very different nowadays. The likelihood of these breakthroughs having a significant impact on our technological future is extremely high.
Take 3D printing as an example. New material discoveries allow us to produce tools, mechanical parts or even functional prototypes in a completely new way.But not only that, it also unlocks a new level of freedom for the manufacturing industry to design and innovate.
In the end, having a wide range of 3D printing materials available makes the product development easier than ever before. Especially when these materials mimic their traditional counterparts but have had certain properties adjusted to fit new applications.
3D Printing Silicone is now possible
One of the most recent developments in additive manufacturing was the emergence of a new technology that enables the use of silicone as a 3D printing material.
The announcement brought excitement to the industrial 3D printing community.
After all, 3D printing with silicone, and by that we mean real silicone, is a game changer.
It serves so many markets: medical, automotive, consumer products. We can safely say that it is one of those breakthroughs that will truly impact our technological future.
ACEO 3D Models in Silicone
Before that, producing silicone parts was only possible through injection molding, casting and compression molding. An extremely expensive process due to the high cost of molds.
Clearly not suitable for the creation of prototypes, bio-models or small batches of products.
Ironically, the reason why silicone was so attractive as a 3D printing material was also what made it not a viable option.
It is not possible to melt silicone by exposing it to heat and then print a 3D object layer by layer like it is with plastics or metals.
For those reasons, several companies have attempted to develop materials that would simulate silicone although it was never truly the same.
The new technology, developed by ACEO ®- the brand for 3D printing with Silicones from the German chemical giant WACKER – have made it possible to create 3D objects from silicone materials without thermal changes.
The technology is a variation of the Material Jetting process based on a “Drop-on-Demand” principle. Basically, the print head deposits single silicone voxels on the build platform.
How does ACEO®'s 3D printer for Silicone work?
According to WACKER, their 3D printer for silicone functions just like an inkjet printer. The workspace and a robot are within a glass case.
One by one, tiny droplets are rapidly extruded from the nozzle onto to the printing area until a fine line is created.
A computer gives the exact coordinates in order to form the desired shape. The area is then exposed to UV Light which causes the silicone to immediately vulcanise.
The process is repeated until the object is formed.
Once solidified silicone does not come back to its liquid state, so the final objects are – just like traditionally produced silicone parts – heat resistant.
Important to mention is the impressive precision with which the robot lays down the droplets to form extremely fine structures.
We have seen structures where the width of the silicone strip was just 0.6mm and half the thickness.
ACEO®'s Silicone material properties
Silicones manifold properties make it suitable for the most diverse applications:
- Temperature and radiation stability, allows it to be exposed to temperatures that vary from -55 to +180 degrees
- It has impressive elastomer properties, with a high variation of hardness being suitable for applications where a low compression set or high flexibility are required.
- ACEO®’s silicones have been tested for biocompatibility, making it a good option for several applications in the medical field.
- It is an insulating material that can be used for sealings in the automotive industry and other hydraulic applications where flow of fluids needs to be secured.
- ACEO® also offers a special grade of silicones that is electrically conductive and can be used in multi-material prints to provide conductivity and resistance for electrical components such as heat pads.
- Available in different colours but also translucent.
Can I buy Silicone filaments and resins?
At the moment, Silicone filaments and resins are not available for the market as most 3D printers for Silicone have been developed by companies that are not machine manufacturers.
On the other hand, silicone filaments and resins that can be found online are not the real deal – so be very careful.
The best way to 3D print in silicone is still through a silicone 3D printing service.
How to start 3D Printing in Silicone?
If you are looking for a silicone 3D printing service, you have come to the right place.
The first step to start 3D printing in silicone is to have a STL or OBJ file of the object you want to print. We prepared this silicone design guideline to help you make sure your part is 3D printable without further modifications.

Can You 3D Print Silicone? Best Silicone 3D Printers and Alternatives
Silicone is a synthetic rubber that boasts several appealing characteristics for manufacturing.
Its chemical structure is amazingly versatile, making it possible to adapt its chemical formula to fit diverse industrial applications from seals to joints, wearables, medical devices, robotic grippers, cooking utensils, thermal and electrical insulation, and more.
Most silicone products today are produced with injection molding, compression molding, or casting. With advancements in 3D printing, many people ask the question, “can you 3D print silicone parts?”
The answer is yes, with some important caveats. Silicone has a very high viscosity, making it difficult to 3D print with it precisely. It cannot be heated and extruded or cured with UV light like photopolymer materials. This means that 3D printing silicone requires highly specialized 3D printers, of which there are only a few inaccessible options available on the market today. However, there are many 3D printing processes that offer 3D printing materials with silicone-like properties, and 3D printing can also be used to create molds for molding silicone parts, bringing many of the benefits of 3D printing to traditional silicone manufacturing methods.
In this comprehensive guide, learn about the different options for silicone 3D printing, its alternatives, and how additive manufacturing supports traditional silicone manufacturing processes.
Silicone 3D printers and their alternative solutions can be divided into three categories:
-
Direct silicone 3D printing: There are silicone 3D printers on the market, but they are still far from being commercially viable or available to the average business.
-
3D printing using materials with silicone-like properties: Common polymer 3D printing processes offer various materials with silicone-like material properties that can serve as alternatives for certain applications.
-
Casting or molding silicone using 3D printed molds: Rapid tooling with 3D printing can bridge the gap between prototyping and mass-producing silicone parts with traditional manufacturing methods.
While most 3D printing technologies have been around for many years or even decades, silicone 3D printers are still a relatively new and experimental field due to the complexity of printing with silicone.
Over the last few years, some companies have brought silicone 3D printers to the market, but these solutions all have certain limitations alongside excessively high costs, which means that they’re not suitable for most businesses and applications.
One of the first solutions for direct silicone 3D printing was a drop-on-demand deposition process developed by the German company ACEO. The drop-on-demand process involved the deposition of small amounts of silicone onto the build platform and the use of UV light to cure them into a finished part. However, this solution failed to find its niche in the market and was discontinued in 2021.
Liquid additive manufacturing (LAM) is another form of silicone 3D printing developed by InnovatiQ (formerly known as German RepRap) that involves dispensing liquefied silicon onto the build platform using an extrusion process that is similar to fused deposition modeling (FDM) 3D printing, and then curing the material with the combination of UV light and heat to form the finished product.
However, with this solution, the design options and the quality of the parts are limited, and the printer costs $120,000.
The silicone additive manufacturing technique developed by Spectroplast works similarly to resin 3D printers and turns silicone materials curable by light.
The latest example of silicone 3D printers is the silicone additive manufacturing (SAM) technique developed by Spectroplast. The SAM process is similar to the vat photopolymerization technique known from stereolithography (SLA) and digital light processing (DLP) 3D printers. Normally, silicone materials cannot be light-cured, but the company uses a proprietary process to turn them light-sensitive. This emerging technology promises to provide the same high degree of design freedom as other resin 3D printing technologies, for a starting price of around $100,000.
Some of the primary reasons why manufacturers choose silicones are the elasticity and flexibility of these materials that empower a wide range of applications.
Silicones generally fall between 10A and 80A Shore durometer hardness. Common polymer 3D printing processes like FDM, SLA, and SLS offer various materials in this hardness range, with various degrees of likeness in other important material properties of silicone such as durability, thermal stability, UV resistance, food safety, biocompatibility, as well as color and translucency options.
For fused deposition modeling, elastomers such as thermoplastic polyurethane (TPU) and thermoplastic elastomer (TPE) are the most flexible materials that can offer an alternative to silicone. These materials are commercially available at Shore 45A to Shore 90A hardness, which covers part of the silicone hardness range, except for the softest materials.
The pros associated with these alternatives are the general affordability of FDM 3D printers and materials. Conversely, the cons include lower precision and dimensional accuracy, low resolution, quality, and part strength, and limited design freedom that all restrict real-world usability.
Silicone-like FDM materials are generally less durable than standard silicone, not food-safe, have lower temperature resistance, and offer limited color and no real translucency options, but they can be biocompatible and skin-safe.
Stereolithography 3D printing is popular among professionals for its high precision and wide range of material options. SLA 3D printing offers multiple alternatives to silicone that empower manufacturers to prototype silicone-like parts or even manufacture end-use parts with the flexibility, elasticity, and durability of silicone. SLA parts offer the smoothest surface finish and a higher degree of design freedom than FDM.
Silicone-like flexible 3D printing resins are generally also less durable than standard silicone, not food-safe, not biocompatible (but can be skin-safe), and have lower temperature resistance. Silicone-like SLA materials can be translucent and can also be dyed to different colors.
SLA 3D printing offers multiple alternatives to silicone that can be used to prototype silicone-like parts or even manufacture end-use parts.
The specific material availability is dependent on the printer model, but generally falls within the 30A and 90A Shore durometer hardness range. Alternative materials to silicone among Formlabs’ SLA 3D printing materials include:
-
Elastic 50A Resin is a soft material that’s suitable for prototyping parts normally produced with silicone. This 50A Shore material is ideal for parts that will bend, stretch, compress, and hold up to repeated cycles without tearing, and spring back quickly to their original shape. Choose Elastic 50A Resin for applications like wearables (straps), stretchable enclosures and casings, compressible buttons, or soft tissue anatomy in healthcare.
-
Flexible 80A Resin is a stiff soft-touch material with an 80A Shore durometer to simulate the flexibility of hard silicones, as well as rubber or TPU. Balancing softness with strength, Flexible 80A Resin can withstand bending, flexing, and compression, even through repeated cycles.
It is ideal for prototyping applications like handles, grips, overmolds, cushioning, damping, shock absorptions, seals, gaskets, and masks, or cartilage, tendon, and ligament anatomy in healthcare. - While slightly beyond the hardness range of silicone materials, Rebound Resin is an 86A Shore elastic 3D printing material that offers unique properties for end-use applications. With five times the tear strength, three times the tensile strength, and two times the elongation of other production-grade elastomeric materials on the market, Rebound Resin is perfect for 3D printing springy, resilient parts. Rebound Resin’s high elongation makes it perfect for tactile, stretchy parts such as handles and grips. It is strong enough to handle constant compression or tension, which is ideal for manufacturing complex gaskets and seals that last.
New Balance shoes incorporating Rebound Resin are already on the market and worn around the world. Rebound Resin withstands the elements, enduring daily use in all weather conditions to outperform and outlast traditional materials.

Selective laser sintering (SLS) 3D printing is the most common additive manufacturing technology for industrial applications. It offers high accuracy, high throughput, and almost limitless design freedom as the unfused powder supports the part during printing and eliminates the need for dedicated support structures.
SLS materials with silicone-like properties include TPU, TPE, and TPA, offering hardness ranges between 45A and 90A Shore. The exact availability is dependent on the printer model.
Parts produced with silicone-like SLS materials are accurate, durable, abrasion and wear-resistant, and have the highest temperature resistance of the three plastic 3D printing processes. They can be biocompatible, skin-safe, and also food-safe after post-processing.
On the downside, SLS printing offers limited color and no translucency options, and designs with thin walls may warp while cooling down.
For those looking to produce real silicone parts, 3D printing can also help bridge the gap between prototyping and mass-producing silicone parts with traditional manufacturing methods.
Injection molding, thermoforming, compression molding, and silicone casting all make use of molds to create the finished silicone product. However, tooling comes with high upfront costs and weeks or months-long lead times from service providers, slowing down product development and extending the time it takes to get a product to market.
Incorporating in-house rapid tooling into the product development process empowers businesses to validate the design and material choice before transitioning to mass production and provides an affordable means to produce custom or limited series of end-use parts.

3d printer for silicone molds and products
With a 3D printer, you can create many complex and unusual products from various materials. In recent years, silicone 3D printing has become increasingly popular, which allows you to create implants, organ prototypes, and other useful products. Let's take a closer look at silicone printing, products that can be created with its help, the necessary equipment and the prospects for the development of new technology.
What is 3D printing silicone?
Silicone is a polymer that consists of chains of alternating silicon and oxygen atoms. This material is resistant to various temperature ranges and various chemicals.
In 2016, Wacker Chemie found the most efficient way to 3D print silicone products. Based on this technology, Fripp Design, Envisiontec, Carbon 3D developed and produced equipment and materials that made it possible to work with silicone on a 3D printer.
Silicone is most often used in the medical industry to create objects that are resistant to changing environmental conditions. Until 2016, it was possible to create medical objects from silicone only with the help of injection molding of thermoplastics (injection molding). However, the new technology of additive 3D printing allows you to create smaller parts at an acceptable cost compared to injection molded products.
3D silicone printing technology
3D printer, which can print silicone products, has the same principle of operation as an inkjet printer. Liquid molten silicone is fed through the extruder in small droplets that are superimposed on each other, forming layers. The printer software is responsible for the correct formation of lines and shapes as a whole.
The curing process is required for the silicone to cure. It is performed using ultraviolet radiation, which forms cross-links between sections of the polymer chain. Due to this, the silicone is strengthened and becomes heat resistant.
3D printed silicone inside a microgel
Silicone 3D printed inside a microgel was developed at the University of Florida. This technology makes it possible to create more durable, but at the same time flexible and comfortable implants. At the same time, the cost of their production will be significantly lower, as well as the final cost for buyers. In the future, silicone printing inside the microgel will allow the creation of various therapeutic devices and very complex structures, such as human organs and tissues.
This 3D printing method allows you to create individual products of various shapes. The printing nozzle moves along a predetermined path and extrudes liquid silicone drop by drop onto the microorganic gel substrate.
Depending on the complexity of the finished product, the printing process can take from several hours to several days.
Application of silicone mold printer
3D silicone mold printer is applicable to the following industries:
- Medicine. Silicone is biologically compatible with the human body, does not have a toxic effect on it and is resistant to the influence of an aggressive environment. Thanks to this, the material is used for the production of:
- individual implants;
- respiratory masks;
- hearing aids;
- ear prostheses;
- training preoperative organ models;
- spectacle nose pads;
- contact lenses.
- Automotive industry. Due to the resistance of silicone to extreme temperatures and solar radiation, it is used for the production of automotive plugs, hose. The presence of waterproofing properties also allow the use of silicone for the manufacture of seals in hydraulic systems and materials for sealing automotive joints.
- Manufacture of everyday or sports articles. The elasticity of silicone and the safety of its use makes it possible to produce insoles for running shoes, ear plugs for headphones, and wristbands.
- Manufacture of souvenirs and jewelry.
Which 3D printer is suitable for silicone products?
What to look for when choosing?
When choosing a 3D printer for printing silicone products, you should pay attention to three main parameters of the device:
- Extruder. It must be inkjet, as liquid silicone is used for printing.
- Integrated heater and pump. To prevent liquid silicone from cooling down during printing and not clumping, the printer must have a heater that will constantly maintain the same temperature. It is also important to have a pump. It will help to evenly supply liquid filament to the work surface from the extruder.
- Closed print area. It is necessary for the vulcanization of the printed blank.
An ultraviolet emitter is located in the printed area, and the area itself is closed with a darkened glass dome.
German RepRap LAM PRE-SERIES 3D printer
Ideal for printing silicone products. It adopts FDM technology, in which two-component liquid silicone rubber (LSR) is mixed by a pneumatic piston and extruded by an extruder. Then each layer of material is thermally cured under the action of an infrared rod.
The FDM technology used by the printer has increased print speed, reduced waste during production, completely eliminated post-processing of the product and accelerated its time to market.
The operation of the device is controlled using the touch screen. The printer uses Simplify3D software to process 3D models.

The future of silicone 3D printing
Silicone printing was originally developed for medical applications. Therefore, the most promising goal is the development and creation of silicone tissues and human organs that imitate real ones with great accuracy.
Help.
The first attempts to create a human organ from a silicone filament were made at the Federal Institute of Technology Zurich. The artificial heart in design and movement completely imitated the real one. However, the silicone model takes only 3,000 strokes to wear out, which is equivalent to a lifespan of less than one hour.
In 2021, only training and demonstration organs are printed from silicone, which help to study human physiology during training in medical specialties. The first experimental implants and prostheses also began to be developed.
Silicone 3D printing with silicone is a new, emerging technology. It is considered very promising due to the ease of use of the material, its high elasticity, wear resistance, resistance to radiation and aggressive chemical environments.

The post will be about the silicone sock. And at first glance, this is a simple thing. But still, it is worth talking about its advantages in detail and point by point:
1) Protection of parts close to the extruder from excessive heating and subsequent deformation.
2) Protection against severe burns from accidental contact with a hot extruder.
3) Protection against plastic sticking to the aluminum block, which in turn can affect printing unpredictably.
4) Screw protection. With sticky plastic, any work with threads on cold or hot will be problematic
5) When the protection is on, temperature fluctuations in the hot extruder will be smaller. Temperature fluctuations occur due to the operation in a repeated cycle of turning on / off the heating. Silicone protection prevents the temperature from dropping quickly when the heating is turned off, and therefore contributes to a more even flow of plastic during printing.
6) This point overlaps with the previous one, but the effect is more pronounced. If you turn on blowing the nozzle (it is also called blowing parts), the air flow can also enter the extruder zone, where the plastic must remain in a molten state - and this is highly undesirable. Therefore, silicone protection also prevents a strong temperature drop even when the part is blown.
In the end, this protection is extremely useful, although for the most part it is not given much attention.
The only thing I would like to note is the difference in quality - different manufacturers have very different quality. The photos show products from different manufacturers. They worked about the same time, about 50 hours. As a result, one practically did not change and will continue to work. The second hardened and lost its elasticity, which led to its damage during removal. It cannot be used further.
I hope the material was useful, I wish you all the best!
