複雑な幾何学

MBJ can create intricate and complex geometries that would be difficult or impossible to achieve with conventional methods. This capability opens up new possibilities for design and innovation.

素材の多様性

MBJ is compatible with a wide range of metal powders, from stainless steel to titanium, offering flexibility in material choice based on the specific requirements of the application.

スケーラビリティ

Whether you need a single prototype or mass production of thousands of parts, MBJ can scale to meet the demand. This scalability is essential for industries that require rapid iteration and development.

Disadvantages of Metal Binder Jetting

Despite its many advantages, Metal Binder Jetting also has some limitations that need to be considered.

後処理の要件

Parts produced with MBJ often require significant post-processing, such as sintering, infiltration, and finishing, to achieve the desired properties and surface finish. This adds time and cost to the production process.

限定された材料特性

While MBJ is compatible with a variety of metals, the properties of the final parts may not always match those produced by traditional methods. For instance, the density and mechanical strength of MBJ parts might be lower.

表面仕上げ

The surface finish of MBJ parts can be rough, requiring additional machining or polishing to meet the required specifications. This can be a drawback in applications where surface quality is critical.

Binder Residue

Residual binder material can sometimes remain in the parts, affecting their performance and quality. This issue needs careful management during the production process.

高額な初期投資

The initial cost of setting up a Metal Binder Jetting system can be high, making it less accessible for smaller companies or startups. However, the long-term savings in production costs can offset this investment.
