About the Material

Advantages:

  1. Complex Geometries: Binder Jetting can produce parts with intricate geometries, including internal channels and lattice structures.

  2. Cost-Effective for Batch Production: Binder Jetting is economical for producing multiple parts simultaneously, making it suitable for medium to high-volume production.

  3. No Support Structures: The powder bed provides natural support, allowing for the creation of complex features without additional supports.

  4. Heat Treatment Flexibility: Stainless Steel 17-4PH can be heat treated to achieve specific mechanical properties, offering versatility for different applications.

Limitations:

  1. Porosity: Parts produced via Binder Jetting may have higher porosity compared to parts made with other metal additive processes, requiring additional post-processing.

  2. Post-Processing Requirements: Sintering or infiltration is needed to achieve full density, which can add complexity to the production process.

  3. Surface Finish: The as-printed surface finish may require additional post-processing, such as polishing or machining, to meet desired specifications.
