SUNLU PETG 3D Filament 1KG 3 Rolls 1.75mm +/-0.02MM 3D Printing Filament Neatly Wound Filament Vacuum Packing Fast Shipping

With extended use, the filament proves reliable — reviewers report that after drying (12 hours at 65 °C) it prints without issues using generic PETG profiles. The material offers good mechanical strength and the glossy finish typical of PETG, with stable interlayer adhesion and low warping. Precise winding without tangles facilitates long prints. Vacuum packaging with silica gel packets keeps the filament dry — several users confirm it arrives relatively dry from the box.

Complaints are minimal. One reviewer mentioned suboptimal spool winding, but this is an isolated case. All others praise diameter accuracy (±0.02 mm), which ensures smooth extrusion even on machines sensitive to variations. Negative ratings are below 2%, indicating high production consistency.
