3D Systems Accura® 48HTR Plastic for SLA® Systems
Categories: Polymer; 3D Printing/Additive Manufacturing Polymer

Material Notes: Accura 48 HTR is a rigid and stiff plastic material for applications that require high-heat resistance, ideal for automotive, aerospace and electronic components testing up to 130 °C/266 °F. Material transparency allows for visualization of internal structures in assemblies and fluid flow analysis. Offering long term stable properties and chemicals resistance, it is ideal for under-the-hood component testing.

Applications:

  • Thermally resistant transparent prototypes
    • Hot or coolant fluid flow visualization
    • HVAC components
    • Under the hood testing
    • Internal structures visualization
    • Electronic controls prototypes
    • Wind tunnel models
Benefits:
  • Suitable for high temperature testing
  • Translucent parts
  • Stable mechanical properties over time
  • Parts are strong and maintain shape
  • Fast recoating and cleaning
Features:
  • Temperature resistant up to 130 °C (266 °F)
  • Rigid and stiff
  • Resistant to common automotive fluids/oils
  • Low viscosity formulation
After thermal postcure 2 hours at 160 °C
