3D printer filament Sunlu PETG 1.75 mm 1 kg — White

Sunlu PETG 1.75 mm filament on a 1 kg spool in white is a thermoplastic filament formulated for FDM/FFF 3D printers. PETG combines tensile strength and moderate flexibility with good layer adhesion and chemical resistance, making it suitable for functional parts, prototypes and household items. The filament is sized for standard 1.75 mm extruders and is compatible with printers that support PETG materials.

Advantages

Sunlu PETG offers a balance between strength and toughness while maintaining easier printability than some engineering plastics. It provides reliable layer bonding and lower warping compared with ABS, plus improved chemical and moisture resistance compared with PLA. The white color gives a neutral finish suitable for post-processing such as painting, sanding or gluing. A consistent diameter and smooth surface help stable feeding and predictable extrusion.

Suitable for

• Functional mechanical parts and brackets
• Durable prototypes and proof-of-concept models
• Household items, fixtures and custom mounts
• Parts that require post-processing (sanding, painting, adhesive bonding)

Key specifications

• Material: PETG (glycol-modified polyethylene terephthalate)
• Diameter: 1.75 mm
• Spool weight: 1 kg net filament
• Color: White
• Compatibility: FDM/FFF 3D printers supporting PETG filament

How to use

Load the filament into a printer designed for 1.75 mm filament and set the hotend temperature according to PETG recommendations for your specific printer and nozzle (commonly 230–250 °C). Use a heated bed (typical range 70–90 °C) or an adhesion surface to reduce warping. Calibrate extrusion multiplier and flow settings for accurate dimensional results, and adjust print speed and cooling to balance surface finish and interlayer adhesion. Store the filament in a dry, sealed container with desiccant when not in use to preserve print quality.

Usage recommendations

For best results, start with moderate print speeds and minimal cooling to maximize layer bonding; increase cooling for finer surface detail as needed. Test small calibration prints to determine optimal temperature and retraction settings for your printer and nozzle size. When painting or gluing, lightly sand the surface to improve adhesion.
