Filament PCTG

PCTG Filament – modern, strong and easy-to-print material for universal use

PCTG filament (PolyCyclohexylenedimethylene Terephthalate Glycol) is a modern engineering material that belongs to the family of advanced copolyesters and represents an improved alternative to PETG filament. Compared to PETG, it offers higher impact toughness, better heat resistance and dimensional stability, while maintaining easy printability and excellent layer adhesion.
Thanks to these properties, PCTG filament is ideal for functional and structural prints that must be strong, durable, yet flexible and dimensionally stable. It is suitable both for technical applications and for aesthetic projects where clarity and a smooth surface are important.

Why choose PCTG instead of PETG

At first glance PETG and PCTG may look similar, but the differences in their properties are significant. PCTG offers up to 20–30% higher impact resistance than PETG, withstands temperatures up to 80–90 °C and has a lower tendency to deform during printing. In addition, it can be printed without the need for an enclosed chamber, which makes it a great choice even for standard desktop 3D printers.

Main advantages of PCTG filaments:

  • Higher toughness and flexibility than PETG

  • Resistance to impacts, heat and chemicals

  • Excellent layer adhesion and stable dimensions

  • Easy to print without warping and stringing

  • High transparency and smooth surface finish

  • Safe, odourless and BPA-free material

Technical and aesthetic applications

Thanks to its combination of strength and flexibility, PCTG is suitable for functional parts, transparent covers, prototypes, jigs, packaging, containers, electronic components or design elements. It is also popular in the automotive industry and jig/fixture production, where impact resistance and shape stability are essential.
The material has high chemical resistance, making it suitable even for parts that come into contact with oils, lubricants or cleaning agents.

Recommended print settings:

  • Nozzle temperature: 240–270 °C

  • Bed temperature: 70–90 °C

  • Print speed: 40–60 mm/s
    PCTG behaves stably even during long prints, does not warp and does not require any special conditions.

Suitable for professional and home use

PCTG filaments are an ideal choice for users who want a material with PETG-like properties, but with higher durability and reliability. Printing is clean and odourless, and the prints are characterised by a semi-gloss surface with fine layer detail. Thanks to its ease of processing, PCTG performs well both in professional environments and for hobby users.

Eco-friendly and safe material

PCTG is BPA-free (Bisphenol A) and fully recyclable, making it suitable even for applications where health safety and user protection are crucial. The material is non-toxic and during printing does not release unpleasant odours or fumes, which is especially appreciated in home use.

Universal material of the new generation

PCTG filament combines the best of PETG and engineering plastics – strength, durability, flexibility and easy printing. It delivers professional results without complex printer tuning and is therefore becoming a new standard among universal filaments.

The PCTG Filaments category offers a modern and reliable material that is perfect for functional, technical and visual projects. A great choice for everyone who wants prints with long service life, high precision and resistance to impacts, heat and the passage of time.
