# SUNLU PETG Filament Refill, 1.75 mm, 4 Colors

## At a glance

- Refill filament is not ready to load on its own, the listing says it must be installed on an empty reusable SUNLU or Bambu Lab spool.
- The listing recommends printing at a nozzle temperature of 240-260°C, bed temperature of 60-70°C, and speed of 50-200mm/s.
- SUNLU claims the PETG refill is compatible with its own and Bambu Lab reusable spools, and says a spool can also be printed for use with most 3D printers.

## Pros

- Four listed colors provide options for multicolor projects across separate prints.
- The refill format can reuse a compatible empty spool instead of requiring a new spool with each refill.
- The listed print settings provide a starting point for tuning a PETG setup.

## Cons

- Requires a compatible empty spool, which is not described as part of the product listing's supplied contents.

## Before you buy

- The listing describes this as PETG refill filament and gives a material value of “Polyethylene Terephthalate Glyco”, confirm the material wording and that the refill fits your spool before purchase. Its toughness, impact resistance, reduced stringiness, clogging, and cost claims are manufacturer claims, not independently verified here.

## A good fit for

- 3D printer owners who already have a compatible empty SUNLU or Bambu Lab spool.
- Users looking for PETG refill filament in four listed colors and prepared to tune print settings.

## Less suited to

- Buyers who need filament ready to mount without sourcing or preparing a compatible empty spool.

## Customer feedback

The supplied aggregate rating is 4.5 out of 5 stars, but no rating count or customer comments are available. That figure alone cannot establish how consistently the refill performs or whether buyers found spool compatibility and print settings convenient, those details matter for use because the listing requires a compatible empty spool.
