3D printer filament eSun EPLA-CF 1.75 mm, carbon-fiber reinforced PLA, 1 kg spool, black

eSun EPLA-CF 1.75 mm is a carbon-fiber reinforced PLA filament supplied on a 1 kg spool in black. Intended for FDM/FFF 3D printers that accept 1.75 mm filament, this composite material combines the ease of PLA printing with increased stiffness and improved dimensional stability compared with standard PLA. The filament is formulated to produce parts with higher rigidity and reduced warping, making it suitable for functional prototypes, fixtures and components that require enhanced mechanical properties.

Advantages

The carbon-fiber reinforcement increases tensile stiffness and structural rigidity while maintaining PLA’s relatively low printing temperature. Improved dimensional stability helps reduce deformation in medium-sized parts. Supplied on a 1 kg spool in a standard 1.75 mm diameter, the filament is compatible with most desktop FDM/FFF systems. Note that abrasive fibers can accelerate nozzle wear, so hardened or wear-resistant nozzles are recommended for prolonged use.

Suitable for

• Functional prototypes and test fixtures that require increased stiffness
• End-use parts with moderate mechanical load and dimensional accuracy requirements
• Jigs, clamps and mounting brackets where reduced flex is beneficial
• Applications where ease of printing of PLA is desired but with enhanced rigidity

Key specifications

How to use

Load the 1.75 mm filament into an FDM/FFF 3D printer configured for composite materials. Use print temperatures typical for PLA as a starting point and adjust according to your machine and part geometry; many setups benefit from slightly higher extrusion temperature to ensure adequate layer adhesion. Print with a hardened or wear-resistant nozzle to prevent accelerated wear from carbon fibers. Use a heated bed and appropriate bed-adhesion method to reduce warping for larger parts, and optimize print speed, retraction and cooling to balance surface finish and mechanical performance.

Usage recommendations

For best results, pair this filament with a hardened nozzle (steel or ruby-tipped) and calibrate extrusion multiplier and temperature. Store the spool in a dry environment or sealed bag with desiccant to maintain print consistency. Test print small samples to refine settings before producing critical parts.
