## Summary description

c-tech Premium Line PETG filament in Water Blue (RAL5021) is a 1.75 mm, 1 kg spool for FDM/FFF 3D printers. PETG offers a balance of strength and ease of printing with good layer adhesion and chemical resistance. Suitable for functional parts, prototypes and decorative prints where durable, slightly flexible and water-resistant material is required.

## Long description

c-tech PETG Premium Line in Water Blue (RAL5021) is a 1.75 mm, 1 kg filament spool designed for FDM/FFF 3D printers. Manufactured for consistent diameter and spool winding, this PETG grade combines mechanical strength, good layer adhesion and increased chemical and moisture resistance compared with standard PLA. The Water Blue color provides a stable, semi-transparent blue suitable for both functional prototypes and decorative parts where a durable, slightly flexible material is required.
Advantages
This PETG filament delivers reliable extrusion and dimensional stability thanks to tight diameter tolerances and uniform coloration. It offers improved impact resistance and toughness versus brittle materials, together with good interlayer bonding that reduces delamination in printed parts. The material's chemical and moisture resistance make it suitable for components exposed to mild solvents or humid conditions, while the Water Blue tone ensures consistent color reproduction across jobs.
Suitable for
Functional prototypes and end-use mechanical parts
Decorative objects and product visualizations
Parts requiring moderate flexibility and impact resistance
Components used in humid or mildly corrosive environments
Key specifications
Filament material: PETG (glycol-modified polyethylene terephthalate)
Diameter: 1.75 mm nominal
Spool weight: 1 kg net filament
Color: Water Blue (RAL5021), semi-transparent to translucent appearance
Compatibility: FDM/FFF 3D printers with 1.75 mm filament drive
Mechanical properties: balanced strength and toughness with moderate flexibility
Chemical resistance: improved resistance to moisture and common mild solvents compared with PLA
How to use
Load the 1.75 mm filament into a compatible FDM/FFF 3D printer and set print parameters according to your printer and part requirements. Typical nozzle temperature ranges for PETG are higher than PLA; consult your printer guidance but start around commonly recommended PETG temperatures and adjust for flow and layer adhesion. Use a heated bed and apply suitable bed adhesion aids to reduce warping and ensure first-layer bonding. Allow printed parts to cool gradually to minimize internal stresses and post-process as needed through light sanding or trimming.
Usage recommendations
For best results, print with a heated bed and moderate print speeds; calibrate retraction and extrusion settings to prevent stringing. Store the filament in a dry environment or sealed container with desiccant to preserve print quality and avoid moisture uptake. Test small calibration prints when changing spool batches or switching machines to confirm optimal temperature and flow settings for the Water Blue PETG.
