Specifications are manufacturer rated, as published on each listing and collected 4 November 2026.
Print speed and settings
Top speed does not separate the sides. The ELEGOO listings state a top speed of up to 600 mm/s, with the bundle listing stating a range of 30-600 mm/s, and the SUNLU listing states a range of 30mm/s – 600mm/s with the same top figure. The difference is in settings detail: the SUNLU listing states a settings table with a hot bed temperature of 70-80℃ and three speed and temperature pairs, at 50-100mm/s with 205-215℃, at 100-300mm/s with 240-250℃, and at 300-600mm/s with 260-270℃. The ELEGOO listings state no nozzle temperature, bed temperature or speed tier table, so those SUNLU figures belong to the SUNLU listing only and should not be borrowed for the ELEGOO filament.
Accuracy and winding
Accuracy is stated for the ELEGOO side only. Both ELEGOO listings state an accuracy of +/-0.02mm, with full mechanical winding and manual inspection stated for neat winding that reduces tangles and snap issues. The SUNLU listing states no accuracy figure, so no accuracy comparison can be made from the listings, and the ELEGOO accuracy figure should not be applied to the SUNLU refill. Both sides state enhanced fluidity for fast printing, with the ELEGOO listings stating rapid melting and smooth flow, and the SUNLU listing stating the same fluidity wording for its high speed PETG.
Spool format and compatibility
Format is the clearest difference. The ELEGOO listings are spooled filament, with a 1KG spool for the single listing and a 4 Pack Bundle for the bundle listing, each spool stated at 1KG. The SUNLU listing is a refill pack of 4KG, with 4 rolls at 1KG per roll, and no spool included, so it needs a reusable spool the buyer already owns. The SUNLU listing states compatibility with the newer SUNLU spool, Bambu Lab spool and other well-known brands, plus most FDM printers, AMS and AMS Lite, while also stating it is NOT compatible with the SUNLU detachable spool named in the listing, so buyers should confirm their spool type before ordering.
Toughness and uses
Both sides claim toughness in similar wording. The ELEGOO listings state PETG as durable, flexible and highly impact resistant, with good light transmittance, less warping and low shrinkage compared to PLA, for parts that involve light diffusion and for daily necessities. The SUNLU listing states toughness, high impact strength for parts that endure bumps and drops, and a combination of PLA ease of use with ABS durability. The SUNLU listing states a 1 Year Manufacturer warranty, while the ELEGOO listings state no warranty term.
