eSUN PETG+ 1.75mm Grey 1kg Paper Spool 3D Printer Filament PETG+175H1P1

PETG+ filament in grey delivers exceptional toughness and impact resistance for demanding 3D printing projects. This 1kg spool of 1.75mm filament combines the ease of printing typically associated with PLA with the durability and temperature resistance closer to ABS, making it a versatile choice for both functional parts and detailed models.

Advantages

eSUN PETG+ is engineered for enhanced mechanical properties. It offers improved impact strength and flexibility compared to standard PETG, reducing the risk of cracking under stress. The filament exhibits low shrinkage and excellent layer adhesion, resulting in strong, dimensionally accurate prints with a smooth surface finish. The grey colour provides a neutral, professional appearance suitable for a wide range of applications.

Suitable for

• Functional prototypes requiring toughness
• Mechanical parts and enclosures
• Outdoor applications due to good UV and moisture resistance
• Educational and hobbyist projects needing reliable printing
• Cosplay props and wearable items that benefit from impact resistance

Recommendations

For optimal results, print with a heated bed at 70-80 °C and consider using a cooling fan at low to medium settings to balance layer adhesion and overhang performance. Store filament in a dry, sealed container with desiccant to maintain print quality. This PETG+ is an excellent upgrade for users seeking stronger parts without the warping issues of ABS.
