Metal Binder Jetting 3D Printing Service
Metal Binder Jetting 3D Printing Service is an advanced additive manufacturing process used to create metal parts by selectively depositing a binder onto a metal powder bed layer by layer. The binder holds the powder particles together until the part is fully formed, after which it undergoes a sintering process to fuse the metal particles into a solid, dense component.
Use Metal Binder Jetting for Fast and Affordable Metal Parts
Metal Binder Jetting is a 3D printing technology that enables the production of complex metal parts with outstanding mechanical properties.
This technology is often chosen for its ability to produce metal parts at a fraction of the cost of traditional metal manufacturing processes, with virtually no design limitations. Binder Jetting machines feature large build areas and deliver high-speed production, making them ideal for low to medium-batch, rapid-turnaround parts. The combination of speed and affordability makes Metal Binder Jetting an excellent choice for industries requiring high-strength components, including industrial, automotive, consumer products, and oil and gas sectors.
Metal Binder Jetting Printing Capabilities
| Feature | Description |
|---|---|

Surface Roughness | 30 to 200 µin Ra, depending on build orientation, finish, and material used for the build |
Density | 95%+ for infiltrated, 98%+ for single alloy. Density is homogeneous. |
What is the Metal Binder Jetting Process
Metal Binder Jetting is an additive manufacturing technology that creates metal parts from a CAD file through a multi-step process. Binder jet machines first fuse layers of metal powder with a binding agent. Once the part is bound, the resulting shape, known as a “green part,” is left to cure. After curing, the part is placed in a furnace to undergo sintering or to be infiltrated with bronze, further solidifying it.
Since binder jet parts are supported by unused powder on all sides, this reduces or eliminates the need for additional support structures and minimizes post-processing. However, as most binder jet parts undergo a furnace stage, they may experience shrinkage, slight porosity, and potential loss of fine details. Engineers should design binder jet parts with design-for-manufacturing principles in mind to account for these factors and ensure optimal part performance.
Metal Binder Jetting Materials
| Material Name | Description |
|---|---|
X1 Metal 420i™ | 420i is a matrix metal composite material composed of 60% 420 stainless steel and 40% bronze infiltrant. This material offers good mechanical properties and offers excellent wear resistance. Its properties behave similarly to 4140 steel. 420i is 95%+ dense. |
X1 Metal 316i™ | 316i is a matrix metal composite material composed of 60% 316L stainless steel and 40% bronze infiltrant. This material offers good mechanical properties and offers excellent wear resistance. 316i is easier to tap and post-machine versus 420i. 316i is 95%+ dense. |
Single alloy 316L SS | A 98%+ dense 316L stainless steel metal with superb corrosion resistance, and excellent feature details. |
Best Applications for Metal Binder Jetting
Available Finishes
420i Binder Jetting metal parts are composed of a steel and bronze composite, resulting in a bronze-silver coloration at wear points. This unique appearance can be enhanced or minimized based on finishing options, such as media blasting, heat patinas, and vibratory media tumbling.
Avinyaworks offers six finishing options for X1 Metal 420i and 316i: Zirblast, Tumble Polished, Medieval Pewter, Damascus Steel, Antique Bronze, and Wheat Penny. For single-alloy metals, Zirblast is the available finish option. These finishes allow for customization of the part’s aesthetic and surface properties to meet specific design requirements.
