I. Technology Overview & Key Advantages

  • The Process:
    • Binder jet printing is used to create a "green" part from stainless steel powder, using a binder material.
    • Excess powder is carefully removed.
    • The part is sintered to burn off the binder and fuse the metal particles.
    • Metal infiltration with bronze fills the pores, strengthens the structure, and joins printed parts, creating a sealed, robust component with a gas-tight interface when capillaries are inserted.
    • Sacrificial structures or powders control infiltration, ensuring microchannels remain open.
  • Key Advantages:
    • Complex Geometries: Enables intricate 3D designs and long, complex microchannels.
    • High-Temperature Stability: Uses metals that withstand high temperatures and thermal cycling.
    • Robust Connections: Creates strong interfaces with capillary tubing, which are essential for fluid transfer.
    • Controlled Infiltration: Sacrificial structures or powders provide precise control over bronze flow, ensuring microchannels remain open.
    • Sealed Microchannels: The infiltration process seals porosity, making the channels gas-tight.
