Understanding the Binder Jetting Process

Binder Jetting operates in a layered fashion, where a print head moves across a bed of powder, selectively depositing a binder. Each layer is then cured, and the process repeats until the final object is formed. The unbound powder acts as a support structure, allowing for the creation of intricate designs without the need for additional supports.

Step-by-Step Process:

  1. Spridning av pulver: A thin layer of powder is spread over the build platform.
  2. Binder Deposition: The print head deposits the binder onto the powder bed according to the design.
  3. Curing: Each layer is cured to solidify the binder.
  4. Layering: The process repeats layer by layer until the entire object is built.
  5. Depowdering: Unbound powder is removed, revealing the finished part.
  6. Efterbearbetning: Additional steps such as sintering or infiltration may be required to achieve desired properties.
