6 Best Alternatives to the SUNLU High Speed PETG 4KG (2026)

Comparing top PETG alternatives

IEMAI High Speed PETG 4kg Bundle

The IEMAI High Speed PETG 4KG Bundle focuses on precision for Bambu Lab and Creality K1 printers. Like the SUNLU option, it offers high-speed printing capabilities, but it limits you to black and white colors. You get a 4KG total weight, matching the original capacity. The IEMAI choice is ideal if you prioritize machine compatibility and consistent layer adhesion over multi-color variety. It trades the SUNLU’s vibrant aesthetic for a more professional, monochrome workflow. If your projects require durable, high-speed prints without color changes, this bundle provides a reliable, streamlined alternative that maintains the same material benefits.

ELEGOO Rapid PETG 1.75mm Filament 4KG Bundle

The ELEGOO Rapid PETG 4KG Bundle matches the SUNLU filament in speed and durability but shifts the color palette. Instead of sky blue, mint green, pink, and orange, you receive blue, green, orange, and yellow. Both products support high-speed printing up to 600mm/s and offer 4KG of material. The ELEGOO option is a strong substitute if you prefer a different set of primary colors while maintaining the same matte finish and impact resistance. It delivers identical performance metrics, making it a seamless swap for makers who want to experiment with different color combinations without sacrificing print quality or speed.

ELEGOO 1.75mm Black PETG Filament 4kg

The ELEGOO 1.75mm Black PETG Filament 4KG removes the multi-color aspect entirely, offering only black. It retains the 4KG weight and PETG material properties, ensuring durable, heat-resistant prints. Unlike the SUNLU bundle, you cannot achieve multi-color effects, but you gain consistency in a single, versatile shade. This option suits users who prioritize mechanical strength and precise dimensions for functional parts over aesthetic variety. It is a practical choice for makers who need reliable, moisture-free storage and consistent layer adhesion for holders and mechanical components, sacrificing color flexibility for focused utility.

YOOPAI 4KG Tough PETG Filament

The YOOPAI 4KG Tough PETG Filament emphasizes dimensional accuracy with a tolerance of plus or minus 0.02mm. It offers a reusable spool system, a feature not highlighted in the SUNLU data. The color scheme includes black and white, providing a neutral palette similar to the IEMAI option. While it matches the 4KG size, it focuses on precision and durability for tough prints. This alternative is best for users who require strict dimensional consistency and reusable packaging. It trades the SUNLU’s vibrant colors for enhanced accuracy and practical spool benefits, making it suitable for detailed mechanical projects where fit and finish are critical.

SUNLU PLA+ 2.0 Filament 4KG White Bundle

The SUNLU PLA+ 2.0 4KG White Bundle shifts the material from PETG to PLA+. It maintains the high-speed printing capability and 4KG size, but you lose the heat resistance and durability of PETG. The color is exclusively white, offering a clean, uniform look. This option is ideal if you prioritize speed and ease of use over toughness. It fits users who want to skip respooling and prefer the lower printing temperatures of PLA+. While it shares the brand and speed features, it serves a different niche, focusing on quick, odorless prints rather than impact-resistant functional parts.

SUNLU 4KG High Speed ABS Filament

The SUNLU 4KG High Speed ABS Filament moves from PETG to ABS, offering heat resistance and durability for functional parts. It maintains the high-speed printing feature and 4KG size, with a color palette of grey, beige, yellow, and olive green. This alternative is suitable for users who need higher temperature tolerance and can manage the printing requirements of ABS. It trades the PETG’s ease of use and matte finish for the superior heat resistance of ABS. If your projects demand robust, heat-tolerant components, this bundle provides a high-speed solution within the same brand ecosystem, adapting to more demanding material needs.
