Acrylonitrile Butadiene Styrene polymer

Is a styrene material that can be used in Fused Filament Fabrication

Notes

• Shrinks as it cools
  • Difficult to print >150 mm objects
  • Don't use fan cooling
• ABS mixing is different from manufacturer to manufacturer
• Used in Lego bricks
• ASA is slightly modified ABS
  • Easier to print
  • Improved mechanical resistance
  • Higher heat deflection
• Color varieties: glow, color-diode

Usage

• Temperature
  • Glass Transition: 105°C
  • Melt at 150°C
    • Extrusion at 220-225°C
      • easier than PLA
• Bed
  • Heated bed
  • Kapton tape
  • Thin layer ABS cement
  • Proprietary glue to reduce warping
• Environment
  • Mild odor, affect chemically sensitive people / birds
  • Airbone microscopic particles than PLA
  • Don't use a fan
• Postprocessing
  • Acetone could be used for smoothing, but it's flammable
