Spectrum PCTG CF10 Black 0,5kg 1.75 mm

Remarkable product enriched with carbon fibres

PCTG is a copolyester that is gaining increasing popularity among users of 3D printing technology. In terms of properties, it is often compared to well know PETG. However, it t is worth noting that PCTG has a significantly higher impact strength compared to its big brother. PCTG’s high elasticity combined with high layer cohesiveness, high viscosity and negligible shrinkage make it a perfect polymer for composite materials.

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.

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.

VERIFY YOUR SPOOL - the most precise quality control system on  the market

Filament for 3D printers is manufactured by the method of free extrusion, which is one of the most difficult processing techniques by extrusion, due to the particularly significant impact of process parameters on product dimensions and material homogenization.

During the production each 1mm of Spectrum Filament is being continuously measured in 2 axes with ±0.8µm accuracy, which allow obtaining a high-quality final product. To prove this, Spectrum Filaments, as one of the few manufacturers in the world, has introduced the possibility of online presentation, individually for each manufactured spool:

• the course of diameter on the entire length of the spool,
• mean diameter,
• ovality,
• standard deviation

Precise survey guarantees that Spectrum Filaments products meet rigorous market requirements.
