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.

  • It is suitable for simultaneous printing of multiple items or batch production, and for small-batch orders.

  • This process is compatible with metals, ceramics, and even sand-based materials, offering excellent material flexibility and enabling a wide range of applications.

  • Since parts are printed in a powder bed, there is no need for additional support structures, allowing for more design freedom.

  • Using powder spreading and binder jetting technology, Binder Jetting achieves thinner layers and better dimensional accuracy.

Features of Binder Jetting 3D Printing

Advantages

Scalability

Binder Jetting can produce multiple parts simultaneously, making it suitable for large-scale production.

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.

Drawbacks

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 3D Printing Applications

Prototypes
Binder Jetting can print prototype parts with complex structures without the need for support structures. It has a wide printing range and is suitable for prototyping equipment shells or mechanical structural components. Compared with SLM etc., Binder Jetting has better detail performance.
Customized Products
The Binder Jetting process is highly suitable for the production of customized products. It is currently one of the most suitable manufacturing solutions for customized products with medium and high precision, complex structures, and diverse materials, especially for the demand of "small quantity and diverse variety".
Batched Products
Binder Jetting is well-suited for high-volume production, particularly for parts that do not require extensive post-processing. It can batch print complex-structured stainless steel gears, couplings, brackets, etc. It does not require support and has good mechanical properties after post-treatment sintering.
