The first of the PCTG-based composites we developed was a carbon fibre version - PCTG CF10. The carbon fibres used give the filament an extremely high stiffness, while reducing the brittle fracture typical for other PETG-based carbon composites. PCTG CF10 filament allows the printing of parts with increased hardness and tensile strength compared to classic PCTG. The use of carbon fibres increases the thermal resistance of the filament, further reduces shrinkage and gives the characteristic carbon matt appearance to the printed models.

Features Specs Support
PCTG is a copolyester that is gaining increasing popularity among users of 3D printing technology. In terms of properties, it is often compared to PETG, which is well known to every printer (in the sense of a maker, creator, person using a 3D printer). However, it t is worth noting that PCTG has a significantly higher impact strength compared to its big brother. PCTGs high elasticity combined with high layer cohesiveness, high viscosity and negligible shrinkage make it a perfect polymer for composite materials.

With Spectrum PCTG CF filament, 3D printing is becoming an even more viable alternative to conventional plastic processing, enabling the production of durable and long-lasting everyday objects, regardless of size.

Key features:

• Heat deflection temperature HDT - 76°C
• High stiffness and tensile strength
• Good impact resistance
• Chemical resistance
• High dimensional accuracy of the printed elements
• Carbon, matt printed surface
• Can be subject to material removal processes


• Visual and functional prototyping
• Ggoodness of fit tests
• Conceptual models
• Manufacture of housings and covers
• Manufacture of parts subject to abrasive wear
• Manufacturing tools and equipment


Filament is reeled on the neat, transparent spool. Each spool contains information on the type of material, diameter and recommended printing temperature. Filament is vacuum-packed with a moisture absorber. Whole product packed in the original, folied Spectrum Filaments packaging.
