Filament PETG transparent — Fiberlogy, REF-EPET-PURETR, 1.75 mm spool

Transparent PETG filament by Fiberlogy, REF-EPET-PURETR, in 1.75 mm diameter, is designed for 3D printing parts that require a combination of mechanical strength, chemical resistance and optical clarity. The material offers good layer adhesion and low tendency to warp compared with many other thermoplastics, making it suitable for functional prototypes, mechanical components and transparent enclosures where visibility of internal parts is important. The filament is supplied on a standard spool and is intended for use with printers that accept 1.75 mm filament and a heated build platform.

Advantages

This PETG filament provides a balance between toughness and printability: it produces durable parts with improved impact resistance and chemical durability compared to standard PLA while retaining easier printing characteristics than some engineering plastics. The transparent grade is formulated to deliver improved clarity after appropriate print settings and post-processing. Good interlayer bonding reduces delamination risk, and the material's dimensional stability reduces warping and curling on the build plate when used with recommended temperature control.

Suitable for

• Functional prototypes and end-use mechanical parts
• Transparent enclosures, housings and covers
• Decorative items requiring clear or translucent appearance
• Parts exposed to mild chemicals or moisture

Key specifications

• Material: PETG (transparent grade)
• Diameter: 1.75 mm
• Spool format: standard feeder spool compatible with most desktop FDM printers
• Typical properties: good layer adhesion, low warping, increased impact resistance
• Recommended environment: heated build surface for best adhesion and dimensional accuracy

How to use

Load the 1.75 mm PETG filament into a compatible FDM printer equipped with a heated bed. Use printer settings optimized for PETG: a nozzle temperature typically higher than PLA and a heated bed to reduce warping. Print slower than PLA if necessary to improve clarity and interlayer bonding. Allow printed parts to cool gradually on the build plate to preserve dimensional stability. If optical clarity is critical, calibrate extrusion, avoid excessive retraction and consider adjusting cooling fan settings to achieve smoother surfaces.

Usage recommendations

For best results, use a nozzle temperature and bed temperature within the PETG recommended range for your machine and perform test prints to fine-tune flow and fan settings. If improved surface gloss or transparency is desired, consider light sanding followed by appropriate polishing or chemical smoothing methods compatible with PETG. Store the filament in a dry environment or sealed container with desiccant to minimize moisture uptake that can affect print quality.
