Fiberon PETG-RCF08 Mechanical & Thermal Properties Printed specimen data shows: Tensile Strength (X–Y): ~59.8 MPa Tensile Strength (Z): ~41.1 MPa Tensile Modulus (X–Y): ~3710 MPa Flexural Strength (X–Y): ~94.6 MPa Flexural Modulus (X–Y): ~3779 MPa Charpy Notched Impact Strength (X–Y): ~4.0 kJ/m² Heat Deflection Temperature (0.45 MPa): ~68.6 °C These specs make it suitable for functional prototyping, automotive components, and consumer goods where rigidity and dimensional accuracy matter. Printing Recommendations Temperatures: Nozzle: 240–270 °C (Polymaker states 270 °C; but profiles suggest the range 240–270 °C) Bed: 60–70 °C Speed & Cooling: Printing Speed: Up to 300 mm/s Cooling Fan: Use 0–50%—reduce fan if you notice layer adhesion issues Nozzle & Hardware: Use a hardened steel or abrasion-resistant nozzle, as the recycled carbon fiber is abrasive and will wear down brass nozzles quickly (typically around 9 hours of life) Chamber / Enclosure: No heated chamber required—room temperature (~20–25 °C) is sufficient Drying & Moisture Management: If the filament is moisture-exposed, dry at 65 °C for 3 h in a regular oven or PolyDryer level 2 for 6 h Store with desiccant; keep relative humidity under ~20% Annealing: Annealing is not required for PETG‑rCF08
