⚙️ Recommended Printing Settings
🌡️ Nozzle Temperature: 210–230°C.
🛏️ Bed Temperature: 45–60°C.
💨 Cooling Fan: 100%.
🏃 Print Speed: Up to 250 mm/s.
💡 Printing Recommendations and Usage Conditions
🔹 Drying: 50°C for more than 8 hours according to the official TDS.
🔹 eSUN recommends optimizing Z seam alignment, layer starting points and travel paths to improve printed surface quality.
🔹 Reduce printing speed when necessary to improve fine details and the stone-like matte appearance.
🔹 Keep the printer enclosure open when chamber temperatures are excessive. Above an ambient temperature of 32°C, eSUN recommends cooling the environment to reduce filament softening near the extruder gears.
🔹 Store the filament in a cool, dry place in a sealed container with desiccant.
