Overview: How Binder Jetting 3D Printing Works?
The Basics of Binder Jetting 3D Printing:
Binder Jetting is an additive manufacturing process that creates 3D objects by depositing a liquid binding agent onto a bed of powder material, layer by layer. It's known for its speed, ability to print in full color (in some cases), and use of various materials like metals, sand, or ceramics.

Features of Binder Jetting 3D Printing
Material Flexibility
The process can be used with metals, ceramics, and even sand, providing a wide range of application possibilities.
No Support Structures
Since parts are printed in a powder bed, there is no need for additional support structures, allowing for more design freedom.
Cost-Effective
Binder Jetting is often more economical for producing large batches compared to other metal 3D printing methods.
Lower Strength
Parts produced via Binder Jetting may require additional sintering or infiltration to achieve full strength, which can add complexity.
Surface Finish
The surface finish may require additional post-processing to achieve smoothness and precision.
Binder Jetting Design Guidelines
| US | Metric | |
|---|---|---|
| Standard Size | 16.93 in. × 11.81 in. × 5.51 in. | 430 mm × 300 mm × 140 mm |
Note: These design guidelines are for general reference only. Actual manufacturability may vary depending on specific part geometry and material.
Binder Jetting Available Materials
SS17-4PH
The strength and hardness of 17-4PH precipitation hardened stainless steel can be significantly improved through heat treatment after sintering. The color of its printed parts is dark gray to black gray in the sintered state. It has good mechanical properties and moderate corrosion resistance, and is suitable for structural parts that require both strength and precision.
- Process:
- Binder Jetting
- Maximum Size:
- 430 × 300 × 140 mm
- Colors:
- Gray-Black
Available Finishes
Default:
- The natural surface of binder jetting printed parts after debinding and sintering, sometimes supplemented with light sandblasting, ensures the parts achieve basic strength and a uniform texture.
Other:
- Post-processing may include curing, sintering, infiltration, or surface finishing to achieve the desired properties and appearance.
Metal Binder Jetting Applications
Design Validation & Functional Prototypes
Produce complex metal prototypes without printed support structures. Metal Binder Jetting is suitable for validating part geometry, assembly, and manufacturability before moving into series production.
Complex & Customized Metal Parts
Manufacture customized components with internal channels, consolidated geometries, and features that may be difficult or costly to produce conventionally. Final tolerances depend on material, geometry, sintering, and secondary machining requirements.
Low-to-Medium Volume Production
Produce multiple parts efficiently within a single build, making Metal Binder Jetting suitable for repeat production of brackets, housings, tooling components, and other small metal parts. Critical surfaces and tight-tolerance features can be CNC machined after sintering.
Engineering note: Binder-jetted parts require debinding and sintering. Dimensional tolerances, density, mechanical properties, and secondary finishing requirements should be reviewed for each application.
