Filament c-tech PETG 1.75 mm 1 kg — PREMIUM LINE, transparent (MPN 3DF-P-PETG1.75-6038)

c-tech PREMIUM LINE PETG filament in 1.75 mm diameter on a 1 kg spool is a transparent material developed for FDM/FFF 3D printers. PETG combines tensile strength with moderate flexibility and reliable layer adhesion, making it suitable for functional parts, prototypes and visible components that require durability and chemical resistance. The filament's transparency supports aesthetic applications where clarity and surface finish matter while maintaining the mechanical properties expected from engineering-grade thermoplastics.

Advantages

Transparent PETG from the c-tech PREMIUM LINE offers a balance between strength and ductility, delivering good impact resistance and reduced brittleness compared with rigid materials. The filament provides consistent extrusion from the spool, predictable layer bonding and resistance to common household chemicals, while being less prone to warping than many other engineering filaments. Its transparency allows for light-transmitting prints and visually clear parts without sacrificing functional performance.

Suitable for

• Functional prototypes and mechanical parts that need toughness and some flexibility
• Visible or aesthetic prints requiring transparent or translucent surfaces
• Enclosures, brackets and fixtures exposed to moderate loads and chemicals
• Household items and tools where durability and neat surface finish are important

Key specifications

• Material: PETG (glycol-modified polyethylene terephthalate)
• Diameter: 1.75 mm nominal
• Spool weight: 1 kg net filament
• Color/optics: transparent
• Compatibility: FDM/FFF desktop and industrial 3D printers supporting 1.75 mm filament
• Mechanical properties: good tensile strength and impact resistance with moderate flexibility
• Chemical resistance: resistant to many household chemicals and moisture absorption lower than some hygroscopic filaments

How to use

Load the 1.75 mm PETG filament into a compatible FDM/FFF printer and set the extruder temperature and print settings according to your printer manufacturer's guidance for PETG. Typical extruder temperatures range higher than PLA; enable a heated bed to improve adhesion and reduce the risk of lifting. Print slower than PLA for optimal layer bonding and surface clarity. Allow printed parts to cool gradually to avoid excessive internal stresses. Store the spool in a dry environment or sealed packaging with desiccant when not in use.

Usage recommendations

For best results, use a nozzle with a diameter suitable for the desired detail, keep printing speeds moderate, and calibrate retraction settings to minimize stringing. When printing transparent parts, increase extrusion width and reduce layer height to improve optical clarity; polishing or annealing post-processing can further enhance transparency.
