3D printing filament Fiberlogy PCTG+GF 1.75 mm 0.75 kg spool — Black

Fiberlogy PCTG+GF 1.75 mm (0.75 kg spool) in Black is a reinforced FDM/FFF 3D printing filament based on PCTG polymer with glass fiber (GF) reinforcement. The material combines the chemical resistance and printability of PCTG with increased stiffness, dimensional stability and improved heat resistance delivered by glass fibers. The 1.75 mm diameter spool is intended for desktop and prosumer printers that accept this filament size and is suitable for producing functional prototypes and durable mechanical parts.

Advantages

Fiberlogy PCTG+GF provides higher rigidity and better dimensional stability compared with standard PCTG, while maintaining good layer adhesion and ease of printing typical for PCTG materials. Glass fiber reinforcement increases stiffness and resistance to deformation at elevated temperatures, making parts more suitable for functional and load-bearing applications. The filament is delivered on a compact 0.75 kg spool in a consistent 1.75 mm diameter to reduce feeding issues and support reliable extrusion.

Suitable for

• Functional prototypes and proof-of-concept models requiring higher stiffness
• Mechanical parts and assemblies exposed to moderate loads
• Components that need improved dimensional stability and heat resistance
• Applications where PCTG’s chemical resistance is desirable alongside added strength

How to use

Load the 1.75 mm Fiberlogy PCTG+GF spool into a compatible FDM/FFF printer following the printer manufacturer’s filament loading procedure. Use nozzle temperatures and print settings appropriate for PCTG-based materials with glass fiber; start with manufacturer-recommended temperature ranges for PCTG and adjust upward if necessary to ensure proper flow and layer bonding. Because of the glass fiber content, consider a hardened steel or wear-resistant nozzle to reduce nozzle wear. Store the filament in a dry environment or sealed container with desiccant when not in use to preserve print quality.

Usage recommendations

For best results, print with a hardened nozzle and moderate print speeds to balance surface quality and extrusion stability. Use a heated bed and good part adhesion methods to minimise warping. Avoid abrasive post-processing methods on delicate features; when sanding or machining is required, use appropriate protective equipment. Verify printer compatibility and perform small test prints to fine-tune temperature and retraction settings before producing critical parts.
