## Summary description

ROSA3D Refill filament is a 1 kg spool of PCTG with 10% carbon fiber reinforcement in 1.75 mm diameter, offered in black. Designed for FDM/FFF 3D printers that support PCTG blends, this composite filament provides increased stiffness and dimensional stability compared to standard PCTG. Suitable for functional prototypes, structural parts and hobbyist or professional prints requiring higher strength and improved surface finish.

## Long description

ROSA3D Filament Refill PCTG + 10CF 1.75 mm 1 kg – Black is a composite 3D printing filament combining PCTG base polymer with 10% carbon fiber reinforcement in a 1.75 mm diameter spool. It is formulated to offer greater stiffness and improved dimensional stability compared with standard PCTG, while keeping good layer adhesion and a smooth matte surface. The 1 kg spool provides material suited for longer print runs and parts that require enhanced mechanical properties and a refined finish.
Advantages
This filament delivers higher tensile rigidity and reduced creep relative to unfilled PCTG, resulting in parts that maintain shape under load. The carbon fiber content improves surface texture and reduces visible warping, while the PCTG matrix retains impact resistance and ease of printing. The 1.75 mm diameter ensures consistent extrusion flow on printers calibrated for that filament size, and the 1 kg spool size supports both prototype iterations and small batch production.
Suitable for
 Functional prototypes and testing models requiring increased stiffness
 Structural components, brackets and housings with moderate load-bearing needs
 Mechanical parts, jigs and fixtures used in workshops and small production
 Hobbyist and professional prints where improved surface finish and dimensional stability are desired
Key specifications
 Material: PCTG polymer with 10% carbon fiber reinforcement
 Diameter: 1.75 mm nominal
 Net weight: 1 kg spool
 Color: Black with matte/semimatte finish
 Recommended extrusion characteristics: elevated stiffness and improved dimensional stability compared to standard PCTG
How to use
Load the 1.75 mm filament onto a compatible FDM/FFF 3D printer designed to accept composite filaments. Use a hardened or wear-resistant nozzle to reduce abrasion from carbon fibers and set extrusion temperatures appropriate for PCTG blends as recommended by the printer or filament manufacturer. Calibrate extrusion multiplier and flow to account for the reinforced material, and allow for modest adjustments to retraction settings to prevent stringing. Print on a heated bed with suitable adhesion aid to minimize warping and ensure first-layer bonding.
Usage recommendations
For best results, use a hardened steel or ruby nozzle, print with a heated bed and moderate enclosure if available, and store the filament in a dry environment to preserve print quality. Test small calibration prints to define optimal temperature and flow before producing critical parts.
