Filament Fiberlogy PETG jasnoszary – Fiberlogy PETG 3D printer filament, light gray

Fiberlogy PETG jasnoszary is a light gray PETG filament formulated for extrusion-based FDM/FFF 3D printers. The material balances ease of printing with reliable layer adhesion and increased chemical and moisture resistance compared to standard PLA. It is intended for producing functional prototypes, mechanical parts, housings and everyday objects where dimensional stability, toughness and moderate flexibility are required.

Advantages

The filament offers consistent diameter and controlled tolerance to support stable extrusion and predictable layer lines. PETG chemistry delivers improved impact resistance and better resistance to humidity and many chemicals than PLA, while remaining easier to print than some engineering plastics. The light gray color provides a neutral, unobtrusive finish that is well suited for visual inspection, post-processing and painting.

Suitable for

• Functional prototypes and proof-of-concept models
• Mechanical components and brackets with moderate load requirements
• Enclosures and housings for electronics and small devices
• Everyday objects, fixtures and replacement parts
• Parts that require good layer adhesion and impact resistance

Key specifications

• Material: PETG (glycol-modified polyethylene terephthalate)
• Color: light gray
• Intended printing technology: FDM/FFF extrusion
• Typical properties: good layer adhesion, increased toughness and chemical resistance
• Finish: smooth, neutral matte-to-semi-gloss surface depending on print settings

How to use

Load the filament into a compatible FDM/FFF 3D printer and use standard PETG printing settings as a starting point. Recommended extrusion temperatures typically lie above PLA temperatures; adjust nozzle temperature, bed temperature and print speed according to your printer and the chosen layer height to optimize adhesion and surface quality. Use a heated bed and appropriate build-surface adhesion (e.g., PEI, glass with appropriate adhesive, or branded build surfaces) to reduce warping. Allow printed parts to cool gradually to reduce internal stresses.

Usage recommendations

For best results, calibrate retraction and cooling to minimize stringing while preserving layer bonding. Post-process with light sanding and priming before painting; avoid prolonged exposure to aggressive solvents. Store the filament in a dry environment or sealed container with desiccant to maintain print quality.
