Product Description

Prusament ASA Jet Black 800g (NFC) is a high-quality ASA filament manufactured directly by Prusa Research on its own production lines. ASA is considered the modern successor to ABS – it is UV stable, shrinks less, has lower odor during printing while maintaining high strength and toughness of prints. Thanks to its excellent heat resistance (without deformation up to approximately 93 °C), the material is ideal for functional and outdoor parts.

This variant uses a new spool with an NFC label according to the OpenPrintTag standard. When placed near a supported printer or read in a mobile application, key material information (type, color, recommended temperatures, and other parameters) is automatically loaded, which significantly simplifies print setup and filament inventory management.

Printing Recommendations

To achieve high-quality prints from ASA, it is advisable to follow specific printing conditions:

• Recommended nozzle temperature: approx. 260 ± 5 °C
• Recommended bed temperature: approx. 110 ± 5 °C
• Recommended print sheet: steel sheet with satin / smooth PEI surface
• Recommended environment:
  • Printing in a closed print chamber / enclosure to minimize warp
  • Avoid drafts around the printer
• Ventilation: ASA contains styrene and releases fumes during printing, so print in a well-ventilated room that can be aired out after printing.

Always carefully degrease the bed surface (e.g., with isopropyl alcohol) before printing and for larger models consider using a brim, skirt, or draft shield to reduce corner warping.

Advantages of ASA compared to other materials

• Vs. PLA
  • Much higher heat resistance
  • Better mechanical and impact resistance
  • More suitable for outdoor and functional parts
• Vs. PETG
  • Higher heat resistance
  • Better UV stability
  • Surface can be more easily sanded and smoothed with acetone
• Vs. ABS
  • Lower shrinkage and warping (warp)
  • Lower odor during printing
  • Better UV stability and resistance to aging
