eSUN PETG Orange 1.75mm 1Kg 3D Printer Filament Price in Sri Lanka

The eSUN PETG Orange 1.75mm 1Kg 3D Printer Filament is an engineering-grade thermoplastic polyester filament engineered for durable functional prototypes, mechanical brackets, high-visibility tooling, and weather-resistant structural components. Synthesized by modifying polyethylene terephthalate with glycol (PETG), it prevents crystallization and brittleness while combining the ease of printing and low thermal shrinkage of PLA with the impact toughness, thermal endurance, and chemical resilience of ABS. Spooled onto an eco-friendly recyclable cardboard spool, this 1.75mm filament provides a tight diameter tolerance (±0.03mm), high interlayer bonding strength, low warping tendencies, and a vibrant, semi-translucent glossy orange finish.

Features

• Superior Layer-to-Layer Adhesion: Fuses aggressively across successive layer lines, producing dense, isotropic, watertight parts that resist structural shear and delamination under mechanical stress.
• High Ductility & Impact Resistance: Yields elastically under shock and dynamic loads rather than fracturing abruptly like standard rigid PLA.
• Chemical & Environmental Resilience: Inert to dilute acids, alkalis, greases, oils, and continuous water exposure, making it suitable for automotive, marine, and workshop environments.
• UV & Weathering Endurance: Resists ultraviolet light degradation and thermal embrittlement, retaining structural integrity and rich orange color saturation in direct outdoor sunlight.
• Low Warping & Shrinkage: Displays a minimal coefficient of thermal expansion, printing large flat footprints on open-frame or enclosed beds without the severe edge lifting typical of ABS or ASA.
• Neat Layer Winding: Spooled with automated tension-controlled winding to eliminate crossed turns and snag-induced mid-print extrusion failures.

Common Applications

• Safety Fixtures & Warning Markers: High-visibility machine guards, emergency stop bezels, lock-out/tag-out (LOTO) tags, and workshop caution indicators.
• Robotics & Drone Platforms: Structural drone arms, motor mounts, battery cradles, and robot bumpers requiring both high impact resistance and clear visual orientation.
• Outdoor & Agricultural Enclosures: Weatherproof sensor boxes, telemetry stakes, irrigation brackets, and field markers exposed to direct sunlight and rain.
• Automotive & Workshop Accessories: Custom tool organizers, fluid reservoir brackets, and duct adapters that resist cabin heat up to ~70°C without softening.
• Custom Electronics Cases: Protective enclosures for development boards (Arduino, ESP32, Raspberry Pi) and heavy-duty portable test instrumentation.

Usage Tips

• Build Plate Adhesion & Surface Protection (CRITICAL):
  • Do NOT print PETG directly onto smooth PEI or bare clean glass without an interface barrier. PETG forms a molecular bond with smooth PEI and glass that can tear off the coating or take divots out of the glass upon part removal.
  • Apply a thin release layer of PVP glue stick, Magigoo, or hairspray, or print directly on a Textured Powder-Coated PEI spring steel sheet.
  • Allow the heated bed to cool down completely below 35°C before removing the part; thermal contraction will cause the print to pop off easily on its own.
• Retraction & Stringing Prevention:
  • Due to PETG's high melt viscosity, dial in retraction to prevent fine cobwebs and oozing.
  • For direct-drive setups, use 0.8 mm to 1.5 mm retraction at 35–45 mm/s; for Bowden extruders, use 4.0 mm to 6.0 mm at 40–50 mm/s.
  • Enable slicer features like "Wipe While Retracting" and "Avoid Crossing Perimeters" (Combing) to wipe the nozzle tip over internal infill before traveling over outer shells.
• Z-Offset Calibration:
  • Unlike PLA, which benefits from being firmly squished into the build plate, PETG prefers to be laid down gently without excessive nozzle pressure.
  • Increase your Z-offset by roughly +0.02 mm to +0.04 mm relative to a standard PLA calibration to keep molten plastic from sticking to the nozzle and causing burnt blobs.
• Drying & Humidity Management:
  • PETG is hygroscopic and absorbs ambient moisture over time, resulting in popping sounds, foamy outer walls, and weak layer bonding.
  • If the spool has been exposed to ambient humidity, dry it in an active filament dryer or convection oven at 60°C to 65°C for 6 to 8 hours before printing, and feed it from a sealed dry box for long multi-day jobs.
• Fan Speed Optimization: Run part cooling at 20% to 50% for general structural parts to maximize interlayer strength. Increase cooling to 60%–80% only during short layer times, bridging spans, and steep overhang angles (>55°).
