2021 Best Binder Jetting 3D Printer – Pros and Cons & Buying Guide

June 9, 2021

There are various techniques and technologies used in printing unique and complex structures with high precision. Binder Jetting 3D printing is one such way. Invented during an MIT project in 1993, the quality of the 3D prints led to the widespread adoption of the technology.

Binder Jetting 3D printing is up to 10x more economical than other metal 3D printing processes, like DMLS/SLM.

Binder Jetting allows the production of complex geometries and shapes with a large build size that requires no support structures during printing, which makes it the go-to printing technique for low to medium metal production.

For instance, its applications range from the fabrication of full-color prototypes (such as figurines), large sand casting cores, and molds as well as manufacturing low-cost 3D printed metal parts.

Unlike traditional manufacturing techniques and some other printing techniques, binder jetting 3D printing ensures good resolution, allowing parts and components to be produced with extremely fine detail.

For example, a clipper brush or a watch ring can be produced cost-effectively compared to traditional manufacturing techniques and with adequate speeds. Binder jetting allows manufacturers to switch to 3D printed parts while maintaining quality.


What Is Binder Jetting 3D Printing and How Does It Work

With a diverse range of applications, it is important for a designer to fully understand and grasp how binder jetting 3D printing works to utilize its full capabilities. Binder Jetting 3D printing creates parts additively with a binding agent.

It works by spreading a thin layer of powder over the build platform after which a carriage containing an inkjet nozzle passes along the x and y-axis of the machine, depositing droplets of a binding agent to bind the powder together. Color ink is also deposited during this step if required.

This process is done layer by layer. When one layer is complete, the build platform moves down and re-coats the surface, and repeats the same process until the whole part is complete.

Depending on the material and its characteristics, it’s not always suitable for structural and load-bearing parts, especially metals and the additional post-processing step can add significant time to the overall build process. After the part is printed, it’s left to cure and gain mechanical strength so it doesn’t break down.

The post-processing step is crucial to add mechanical strength and performance to the print part, and in the case of colors, it also adds vibrancy to the part. After curing, the part is removed and unbound and excess powder is removed via pressurized air.


Now, depending on the material, a post-processing step is usually required. Metals, for instance, need to be sintered or infiltrated with a metal that has a low melting point, typically bronze. In infiltration, the part is placed inside a furnace and the binder is burnt out leaving voids.

The resulting part is approx. 60% porous at this point and as mentioned before, bronze is then used to infiltrate the left voids, which results in low porosity and good strength.

Sintering is where the part is placed inside the furnace after printing, where the binder is burnt out and the metal particles remaining are bonded together to ensure low porosity.

Colored parts, on the other hand, are coated with an infiltrant to improve strength and add vibrancy to the colors. Another layer of epoxy can be added after this to further improve strength.

It’s important to ensure the CAD model fed to the printer contains the appropriate color information on a per face approach or as a texture map.

The former is easier to do but texture maps allow finer controls and details to be added. Perhaps the most common use case for binder jetting 3D printers is sand casting and molds.


It’s low cost and fairly quick, which makes it an excellent solution for elaborate and complex designs. The cores and molds are usually printed with sand or silica and then are generally immediately ready for casting.

At this point, the casted metal component is removed by breaking the mold and even though the molds are used only once, the time and cost saved compared to traditional manufacturing methods is substantial.

Commonly used materials in binder jetting 3D printing are metals, sand, and ceramics in granular form. Material variety is still limited in binder jetting 3D printing compared to other techniques but it’s gradually improving.

Once the printing job is complete, the part is carefully freed from the build box and the remaining powder is removed with brushes or air blowers. Parts also need to be cured to increase their resistance.

Depending on the material, an extra step is also necessary. For instance, in the case of ceramics, it is necessary to cover them with acrylics to increase the mechanical resistance of the pieces and to improve the colors.

Rules Of Thumb

When choosing to go with binder jetting 3D printing there are a couple of things to keep in mind. For instance, metal parts can be printed at a low cost but for applications that require structural parts and high performance, it’s better to stick to DMLS/SLM.


Even though binder jetting offers design freedom, the porosity leads to metal parts that cannot be used as structural parts and thermal effects are not a big issue during the manufacturing process.

Similarly, colored parts produced with binder jetting are brittle and are most suitable as decorative items. The most appropriate use case for binder jetting is producing sand casting cores, molds, and prototyping at a large scale.

What Are the Benefits of Binder Jetting 3D Printers?

As we alluded to earlier, binder jetting 3D printing allows the production of complicated, detailed, and complex parts in a short time period.

It is highly customizable and requires no support structures as that job is fulfilled by the surrounding powder. This allows the creation of parts with few geometric restrictions.

Additionally, in binder jetting 3D printing, parts do not need to be attached to the build platform, which means the whole build volume can be fully used and it makes it ideal for low to medium batch production.

Crucially, binder jetting 3D printed parts bond at room temperature, which means that warping due to temperature is not a problem and is a key advantage binder jetting holds over other 3D printing processes.


It allows binder jetting machines to have a larger build volume compared to all 3D printing technologies and thus binder jetting can manufacture large and complex metal geometry parts as it’s not limited by any thermal effects, such as warping. This also allows parallel manufacturing of multiple parts and components at a time are possible.

Part strength is an issue with binder jetting 3D printing, it’s offset by the cost. With so many key advantages, binder jetting has become a mainstay in the industry and is used widely in a large number of applications. Typically, its capabilities are best utilized for low to medium batch production.

Buyer’s Guide

Binder jetting 3D printing is a great way to create parts or prototypes. There are different types of printers for different types of functions.

Binder jetting 3D printers range from desktop use to full industrial setting and you need to know how frequently you will use the printer.

If you plan to use the printer once in a while, you can employ a 3D printing service instead of purchasing a binder jetting 3D printer, which can prove expensive. In other words, you should consider purchasing one for mass production.

Out of the printers listed above, ComeTrue is the only true home 3D printing and desktop 3D printer with binder jetting technology.

Materials also come into play here. For instance, the VX1000 is restricted to silica sand and PPMA and is mostly suitable for manufacturing sand cores, molds, and plastic parts.


Ease of use is also a factor when it comes to buying a binder jetting 3D printer, especially for small to medium businesses that want to spend more time on their product design and want a seamless user experience.

This is where Desktop Metal’s Production system comes into play offering best-in-class print quality, speed as well offering a mostly tooling-free experience.

Ease of use can also be attributed to a large and well-defined ecosystem around a product making it an additional plus when buying.

3D Systems Projet CJP 860pro offers not only a great color binder jetting 3D printer but also a well-thought-out ecosystem. Another consideration when it comes to buying binder jetting 3D printers is the kind of parts that you need to print.

Binder jetting is great for producing high-resolution parts at great speeds, metal parts will have an internal porosity.

Post-processing steps, such as sintering and infiltration, result in 97% and 90% dense parts respectively. This can affect the mechanical properties and can lead to cracks.

There are ways to circumvent this (Hot isostatic pressing) but it’s recommended that DMLS or SLM be used for metal parts where strength is critical. So, if the use case rests on producing metal parts that will be put under stress, it’s better to invest in other solutions.


On the other hand, binder jetting is great at producing parts quickly, especially for prototyping and cast molds. It’s also great at mass-producing parts, molds, and components.

Frequently Asked Questions (FAQs)
