eSUN PETG+ HS Silver 1.75mm 3D Printing Filament

This filament is optimized for high-speed printing, supporting speeds from 40 mm/s up to 300 mm/s. Achieving the highest speeds requires fine-tuning extruder temperature between 220-260°C and ensuring adequate cooling, possibly with an enclosure, to manage thermal characteristics effectively for layer adhesion and dimensional accuracy.

eSUN PETG+ HS is formulated with enhanced polymer chains that contribute to its high impact strength and flexural resilience. This design minimizes brittleness often seen in other PETG variants, ensuring printed parts can withstand significant mechanical stress and retain their structural integrity in demanding functional applications, leading to longer service life.

For optimal bed adhesion with eSUN PETG+ HS, a heated bed temperature between 70-80°C is recommended. Using an adhesive like a glue stick, Kapton tape, or a PEI sheet can further enhance first-layer success. Calibrating the Z-offset accurately is crucial to ensure proper squish and prevent warping, particularly on larger prints.

Yes, eSUN PETG+ HS exhibits excellent chemical resistance, tolerating various harsh substances, and is inherently waterproof. These properties make it highly suitable for outdoor applications where parts are exposed to environmental elements like moisture, UV, and potential chemical contact, ensuring long-term performance and durability without significant degradation.

Like most hygroscopic filaments, PETG+ HS benefits significantly from proper drying, especially before high-speed printing. Recommended drying settings are around 60-70°C for 6-8 hours. This process helps prevent issues like stringing, bubbling, and poor layer adhesion, ensuring optimal print quality and mechanical properties are maintained.
