What to know before buying
Listing details to confirm
The listing details are inconsistent: the title says 4KG and Black*4, while a feature describes 1KG/Roll. It also names SUNLU 2025 and 3rd reusable spools but says it is not compatible with a SUNLU 2rd detachable spool. Confirm the amount per refill and your exact spool model before ordering. The up-to-600mm/s speed is a manufacturer claim, not a guaranteed result for every printer.
Who is it for?
A good fit for
- 3D-printing users seeking black, 1.75 mm PETG in a multi-kilogram refill listing.
- Owners of a compatible reusable spool who want to reduce reliance on disposable spools.
- Users whose printer setup and settings support experimenting with high-speed PETG printing.
Less suited to
- Buyers who need filament supplied on a conventional spool, or who cannot confirm they have a compatible reusable spool.
- Users who require a confirmed, uniform 1 kg-per-roll pack quantity without checking the listing details.

Only aggregate ratings are supplied, with a broadly positive overall distribution but a smaller share of lower-star ratings. This offers limited reassurance for this PETG refill and does not identify what customers liked or disliked. It cannot confirm spool fit, the refill quantity breakdown or achievable print speed, so those listing details remain important to check.
Frequently asked questions
How much filament is listed?
The title and item details list 4 kg, while a feature refers to 1 kg per roll. Confirm the quantity and refill breakdown on the selected listing before ordering.
Will the refill fit my spool?
The listing claims compatibility with SUNLU 2025 new spools and Bambu Lab spools, among others, but says it is not compatible with a SUNLU 2rd detachable spool. Check your exact spool model.
Does it print at 600mm/s?
The manufacturer claims a range of 30mm/s to 600mm/s. That is not a guaranteed speed for every printer or setup.
