SUNLU PLA Filament Refill, 1.75 mm, 4 kg, Four Colors

Colors: SUNLU PLA Filament Refill is a four-color, 4 kg supply of 1.75 mm filament for 3D printing. It is a refill rather than a ready-to-use spool, so you need a compatible empty reusable spool before printing.

Customer feedback is favorable about filament quality, print finish and color consistency, and mentions use with Bambu P1S printers. Reports are not uniformly positive: some customers describe tangles and clogging, while spool winding and fit receive mixed feedback, including reports of poor winding or fit with standard spools. This matters particularly because the refill must be installed on a compatible spool before use. The aggregate ratings are mostly five-star, but do not resolve those fit and handling concerns.

Negative themes
