Filament eSun PETG+HS 1.75 mm Green 1 kg — PETG (Polyethylene Terephthalate Glycol)

eSun PETG+HS is a 1 kg spool of green PETG (Polyethylene Terephthalate Glycol) filament with a 1.75 mm diameter and a high-speed formulation. It is formulated for faster solidification and improved cooling during printing, reducing nozzle adhesion issues and enabling higher printing speeds while retaining waterproofing, chemical resistance and elevated toughness for functional parts and prototypes.

Advantages

The PETG+HS formula offers faster and more reliable cooling solidification compared with standard PETG, which helps reduce filament sticking to the nozzle and lowers the chance of print failures at higher speeds. It provides good impact strength, chemical resistance and waterproof properties suitable for durable functional prints while remaining cost-effective for general use.

Suitable for

• Functional prototypes and mechanical parts
• Durable housings and enclosures that require water resistance
• General-purpose prints where toughness and chemical resistance are important
• High-speed printing workflows on compatible 1.75 mm extruders

When it may not be suitable

This filament may not be the best choice for very high-temperature applications or parts that require extreme heat resistance beyond PETG’s typical range. Extremely detailed micro-features that rely on very slow, low-temperature printing might not benefit from the high-speed formulation.

Key specifications

• Material: PETG (Polyethylene Terephthalate Glycol)
• Diameter: 1.75 mm
• Spool weight: 1 kg
• Colour: Green
• Formulation: High-speed (optimized for faster cooling solidification)
• Impact strength: 5.86 kJ/m²

How to use

Load the 1.75 mm filament on a compatible extruder and set print temperatures according to your printer and nozzle; start with typical PETG settings and adjust for the high-speed formula—use adequate part cooling to benefit from the faster solidification. Ensure good bed adhesion with a suitable build surface or adhesive and print test pieces to fine-tune speed and temperature settings for consistent extrusion and layer bonding.

What to consider before purchase

• Ensure your printer supports 1.75 mm filament and desired high printing speeds
• Confirm required dimensional tolerance and spool weight (1 kg) meet your project needs
• Verify that PETG’s thermal and chemical properties are appropriate for the intended application

Usage recommendations

Use moderate to high print speeds compatible with your machine, enable targeted part cooling to maximize the benefits of the HS formula, and perform calibration prints to find optimal temperature and speed balance for consistent, durable results.
