PA 12 glass bead part

PA12 (Nylon 12) with glass bead reinforcement is a composite material used in additive manufacturing processes like Multi Jet Fusion (MJF). PA12 is a common thermoplastic nylon material known for its durability, flexibility, and resistance to wear.

The addition of glass beads enhances its properties by providing
  1. Increased stiffness: The glass beads reinforce the nylon matrix, adding rigidity and strength to the final 3D printed parts. This can be beneficial for applications requiring higher structural integrity.
  2. Improved dimensional stability: The addition of glass beads can help reduce shrinkage and warping during the printing process, leading to parts with more precise dimensions.
  3. Enhanced surface finish: The presence of glass beads can contribute to a smoother surface finish, which is beneficial for certain applications.

Rapid High-Resolution 3D Printing with Enhanced Mechanical Properties

In Multi Jet Fusion, a technology developed by HP, layers of powder (in this case, PA12 with glass beads) are selectively fused together using agents and heat to create 3D printed objects. This process allows for relatively rapid production of parts with high resolution and good mechanical properties.

Technical Specifications

  1. Material Type: PA12 (Nylon 12) with glass bead reinforcement.
  2. Mechanical Properties:
    Tensile Strength: Typically ranges from 40 MPa to 60 MPa or higher depending on the glass bead concentration.
    • Elongation at Break: Approximately 10% to 20%.
    • Flexural Modulus: Enhanced due to the presence of glass beads, commonly ranging from 1500 MPa to 3000 MPa.
  3. Thermal Properties:
    • Melting Point: Around 178°C to 185°C.
    • Heat Deflection Temperature (HDT): Improved due to the addition of glass beads, approximately 150°C to 170°C.
  4. Surface Finish: MJF generally produces a relatively smooth surface finish, and the addition of glass beads can further enhance this quality.
  5. Dimensional Stability: The glass bead reinforcement often leads to reduced warping and shrinkage during the printing process, contributing to better dimensional accuracy in the final printed parts.
  6. Layer Thickness: Common layer thickness in MJF is usually around 80 to 100 microns, which can affect the overall surface quality and resolution of the printed part.
  7. Density: The density of PA12 with glass bead reinforcement can vary but typically ranges around 1.01 to 1.02 g/cm³.
  8. Build Volume and Resolution: Specific to the MJF 3D printing technology used, the build volume and resolution will depend on the specific printer model and capabilities.
  9. Weather Resistance: TPU can be formulated to be resistant to weathering effects, including exposure to UV radiation and temperature changes.
  10. Chemical Resistance: PA12 in general is known for good resistance to chemicals, oils, and greases, and the addition of glass beads might slightly alter these properties.
