The Binder Jetting Process

As with most additive manufacturing processes, Binder Jetting is also based on digital CAD data sets. These are sliced by the print software into extremely thin layers. Two key components then work together in the printing system: the recoater and the print head. The recoater applies a micrometer-thin layer of powder material to be printed onto a building platform.

The print head then passes over the platform and selectively applies a binder to those areas of the building platform where the component is to be printed according to the sliced data set. The platform is then lowered by exactly one layer thickness and the recoater applies a new layer of powder, which is again selectively bonded by the print head.

These process steps are repeated until the component is completely printed within the powder bed. The component can then be unpacked from the box and cleaned of excess, non-bonded material.

Advantages & Limitations Of Binder Jetting

Binder jetting has some key advantages over other, more advanced 3D printing techniques. This section will explore some of the benefits and downsides of binder jetting 3D printing.

The advantages of binder jetting printing are:

  • Metal binder jetting is over 10x more economical than other metal 3D printing techniques
  • Binder jetting printers can manufacture very large parts with complex geometries, and is not held back by thermal effects such as warping, shrinking, etc.
  • Binder jetting requires no support structures and does not need to be fused to the build platform
  • Binder jetting is a great technology for low to medium batch production
  • Full-color parts are available in binder jetting, making it great for visual prototypes and colorful parts

The limitations of binder jetting printing are:

  • All parts require post-processing. These steps add significant time to the build and introduce many inaccuracies in the print, even if it was perfect right out of the printer.
  • Parts made in binder jetting printers have inferior mechanical properties when compared with other 3D printing techniques, even with post-processing
  • Binder jetting prints are brittle and only have rough details, making fine details difficult/impossible to achieve and restricting print designs
  • Binder jetting has a small list of materials when compared to other 3D printing technologies
  • Binder jetting printers are very expensive to purchase upfront

How Does Binder Jetting Differ From Other Additive Techniques

There are a wide range of 3D printing methods today, and there is often confusion about the pros and cons of various offerings. Binder jetting is renowned among additive manufacturing methods specifically for its high volumetric output.

Among additive manufacturing technologies, it’s also the most similar to traditional paper printing in its simple approach and speed. The binder functions like the ink as it moves across the layers of powder, which like paper, forms the final product.

3D printing straight from CAD files enables foundries to eliminate the months-long lead times and high costs of traditional patterns and core boxes created from wood or metal. The design freedom of additive manufacturing also allows designers to innovate the parts made with the reliable casting process creating complex, consolidated geometries that enable lightweighting and optimized part performance not possible with traditional processes.Because of its high-speeds and material flexibility, binder jetting stands alone among 3D printing methods as a technology that could transform traditional high-volume manufacturing and bring the design, cost and sustainability advantages of 3D printing to the masses.

One reason why you should be overly cautious when it comes to technology investing is that great stories dont often make for great investments. You also need a stomach for volatility since technology stocks are extremely volatile. Thats because technology itself changes so fast. Before you know it, your golden goose egg has pulled a Bind Therapeutics. Theres also the notion of Gartners Hype Cycle which says that even though a technology may have great potential, it often takes a while for the potential to be realized. That means lots of stock price volatility that most investors find difficult to handle.

Thats where we seem to be with 3D printing, and popular 3D printing stocks appear to be slowly trudging up the slope of enlightenment recently. Here are a handful of 3D printing stocks that were hitting new highs back when 3D printing was cresting over the peak of expectations along with their 5-year returns:

  • Stratasys From $111.94 per share to $22.98 a share 5YR return of -79%
  • 3D Systems From $60.07 per share to $10.92 a share 5YR return of -82%
  • ExOne From $39.93 per share to $9.59 a share 5YR return of -76%

Binder Jetting With Metal

Binder Jetting can also be used to produce metal parts. The process involves metal powder being bound using the polymer binding agent. Like with sand, Binder Jetting allows for the creation of geometrically complex parts that traditional manufacturing methods simply cannot do.

Metals compatible with Binder Jetting include stainless steel, inconel, copper, titanium and tungsten carbide. In the near future binder jetting may be easily compatible with thermoplastics, too.

To create functional, strong metal parts, a secondary process is recommended. Depending on the intended functionality of the part, either infiltration or sintering is performed. These two processes are described below:


Once the part has cured, it is removed and placed inside a hot furnace. The binding agent is heated until is burns off, reducing the part to approximately 60% density and leaving voids in the part.

Bronze is then used to fill in these non-dense parts until the part is has over 90% density and is far stronger it infiltrates the gaps. Parts created through this technique however are still less strong than parts created through powder bed fusion such as Electron Beam Melting or Direct Metal Laser Sintering.


Sintering can be done instead of infiltration in some situations. Once the part is cured, it is sintered in the furnace until it reaches a high density of at least 97%.

Mechanical Properties Of Bjg Parts

Because it used binders as adhesives in BJG, the material qualities are not ideal for structural applications for aerospace and vehicle parts, as they may cause porosity, as in the standard sintering method. The printing process is quicker than SLM/EBM methods and may be sped up by increasing the number of print head holes that deposit the material and binder. It also provides a two-material approach in which different powder-binder combinations can cause variable mechanical capabilities by adjusting the powder-binder ratio.

It can also employ coarse powders in this method, which reduces the cost of producing fine particles. Because these methods dont heat up during the building process, there are no residual stresses in the parts, unlike the SLM process, which does. BJG is one of the most cost-effective AM components for creating three-dimensional objects with additional functionality. Because there is no melting in the BJG process and the consolidation takes place through sintering, there is always the chance of porosities, and the volume, size, and form of the pores may change across components produced in the same batch.

Because we print the part with a binder, we expect the part to have a coarse microstructure. We cure, sinter, and anneal the parts after printing. As a result, the mechanical properties of BJG parts are not as robust as those of SLM/EBM parts.

Binder Jetting Disadvantages / Limitations

  • Low part strength: even with sintering or inflitration, parts created through Binder Jetting are not as strong as parts created through powder bed fusion. They often have less mechanical strength, and break/elongate at lower force.
  • Less accurate than Material Jetting: therefore Binder Jetting loses out in some cases of full color printing.

Bjg Multi Phase Process

GE teases details of prototype H1 binder jet 3D printer

BJG technology can process metals/alloys and ceramics . It should, however, function with any powder-based product and allow for color printing. The BJG process utilizes the components metal/ceramic-based material and a binder substance that glues the metal/ceramic powder material between and within the layers. The binder is often a liquid, whereas the metal/ceramic is a solid powder.

The printing operation is similar to any other approach for creating an AM part. According to the Computer-Aided Design model, the metal/ceramic is spread and covers a layer of binder over the powder metal/ceramic layer. This method is a four-step process that starts with the printing of parts, followed by curing, de-powdering , and sintering and ends with annealing and finishing. These post-processes, the sintering of the parts, can take even longer than the printing itself and involve considerable expenditures.

One of the most notable advantages of BJG is that it may manufacture the pieces without the use of support structures. The machine prints the individual parts onto an unbound loose powder bed. As a result, it may layer the whole construction volume with many sections with just a few layers of space between them.

Metal 3d Printing & Metal 3d Printers: Changing Manufacturing

There are a number of metal 3D printing technologies which have been around for many years. These include perhaps the most notable, Direct Metal Laser Sintering, or DMLS. This is similar to Selective Laser Sintering in terms of process, though DMLS involves 3D printing metals such as stainless steel and cobalt-chrome, whereas SLS uses plastics such as Nylon.

Other metal 3D printing technologies such as Electron Beam Melting, Binder Jetting, and Directed Energy Deposition are also used however.

These technologies are helping improve our daily lives in a variety of ways. Firstly, custom metal parts on rockets and planes are an improvement on typically manufactured parts as they can be printed lighter and stronger. This reduction of weight is critical for cutting costs in an industry where removing one olive from each salad served to passengers can save an airline $100,000 per year.

Therefore, we listed 10 metal 3D printer startups and companies who are changing metal 3D printing.

How Does Binder Jetting Work

Here is how the Binder Jetting process works:

I. First, a recoating blade spreads a thin layer of powder over the build platform.

II. Then, a carriage with inkjet nozzles passes over the bed, selectively depositing droplets of a binding agent that bond the powder particles together. In full-color Binder Jetting, the colored ink is also deposited during this step. The size of each drop is approximately 80 m in diameter, so good resolution can be achieved.

III. When the layer is complete, the build platform moves downwards and the blade re-coats the surface. The process then repeats until the whole part is complete.

IV. After printing, the part is encapsulated in the powder and is left to cure and gain strength. Then the part is removed from the powder bin and the unbound, excess powder is cleaned via pressurized air.

Depending on the material, a post-processing step is usually required. For example, metal Binder Jetting parts need to be sintered or infiltrated with a low-melting-temperature metal . Full-color prototypes are also infiltrated with acrylic and coated to improve the vibrancy of colors. Sand casting cores and molds are typically ready to use after 3D printing.

This is because the parts are in a “green” state when they leave the printer. Binder Jetting parts in the green state have poor mechanical properties and high porosity.

Processable Materials And Their Properties

  • When deciding which AM technique to use, it helps to know the kind of material you are working with.
  • HEAs comprise over three or four elements in equiatomic form with a wide variety of melting temperatures, making them challenging to treat using any fusion method.
  • It employed several reports on the processing of HEAs by SLM and EBM but because of the challenges involved.
  • BJG is the obvious choice because it reduces the process complications observed in the SLM/EBM processes.
  • Super high strength materials, such as diamond, which also has a high melting point, cannot be process by EBM or SLM hence, BJG is the only option.
  • SLM/EBM processing of diamond may cause an undesirable phase shift in the diamond.
  • When youre working with glassy/amorphous materials, you might not be able to use EBM because their high temperatures will crystallize them.
  • When used to process amorphous alloys, BJG cannot provide enough cooling rate control because the amorphous alloys crystallize too during de-binding and sintering.Thus, SLM may be the only processing technique with enough cooling rate control to treat such amorphous alloys.
