3D printer filament Renkforce PLA-CF 1.75 mm 1 kg — carbon fiber reinforced, high tensile strength, rigidity, Black

Renkforce PLA-CF 1.75 mm is a carbon-fiber reinforced PLA filament presented on a 1 kg spool in black. The material combines standard PLA processing characteristics with short carbon fibers dispersed in the polymer matrix to increase tensile strength and stiffness. It is intended for FDM/FFF 3D printers that accept 1.75 mm filament and for applications where improved mechanical properties and dimensional stability are required compared to unfilled PLA.

Advantages

The carbon-fiber reinforcement provides higher tensile strength and improved rigidity while retaining much of PLA's ease of printing. The filament offers good layer adhesion and reduced part deformation under load, resulting in functional parts with better structural performance. Its black color gives a uniform, technical appearance suitable for prototypes and end-use components.

Suitable for

• Functional prototypes that require increased stiffness and strength
• Mechanical parts, brackets and mounts
• Lightweight structural components and fixtures
• Tooling aids, jigs and fixtures for assembly
• Visual-technical prototypes where surface finish in black is acceptable

Key specifications

• Filament diameter: 1.75 mm
• Spool weight: 1 kg
• Base polymer: PLA with carbon fiber reinforcement
• Color: Black
• Material properties: increased tensile strength and rigidity compared to standard PLA
• Compatibility: FDM/FFF 3D printers designed for 1.75 mm filament and compatible with composite filaments

How to use

Use the filament with an FDM/FFF 3D printer that supports 1.75 mm filament. Ensure the printer hotend and feeder are suitable for abrasive or composite filaments; a hardened steel nozzle is recommended to reduce wear from carbon fibers. Typical printing temperatures for PLA-based composites are moderately higher than standard PLA—adjust the nozzle and bed temperatures according to the printer manufacturer's guidance and perform a temperature tower if needed. Print settings should include moderate print speeds, sufficient cooling where appropriate, and slightly increased infill or wall thickness to take advantage of the material's mechanical benefits. Store the filament in a dry environment or sealed container with desiccant when not in use.

Usage recommendations

To extend nozzle life, use a hardened or abrasion-resistant nozzle and avoid prolonged printing with soft brass nozzles. Calibrate extrusion and bed leveling before printing functional parts. For best results with mechanical components, increase shell count and infill density and consider post-processing steps such as annealing if compatible with the part geometry and application.
