Filament spool eSun EPLA-CF 1.75 mm purple, 1 kg, carbon-fiber filled PLA

eSun EPLA-CF 1.75 mm purple is a 1 kg spool of PLA filament reinforced with carbon-fiber filler, designed for FDM/FFF 3D printers. The filament delivers the printing ease of PLA combined with increased stiffness and a matte, textured surface from carbon content. Supplied in a 1.75 mm diameter, this purple carbon-fiber filled PLA is intended for users who need improved rigidity and refined surface appearance for prototypes, functional components and visual models.

Advantages

The carbon-fiber reinforcement increases part stiffness and reduces warping compared with standard PLA while maintaining low printing temperature and good layer adhesion. The matte finish masks layer lines and gives printed objects a textured, professional look. The 1.75 mm diameter ensures compatibility with most desktop FDM printers and the 1 kg spool provides a balance between usable quantity and storage convenience.

Suitable for

• Functional prototypes and mechanical parts requiring higher stiffness
• Visual models and decorative items with a matte, textured surface
• Jigs, fixtures and tooling components for light-duty use
• Hobbyist and professional prints where dimensional stability is important

Key specifications

• Filament material: PLA with carbon-fiber filler
• Nominal diameter: 1.75 mm
• Spool weight: 1 kg
• Colour: purple (matte, textured finish)
• Compatibility: FDM/FFF desktop 3D printers using 1.75 mm filament
• Mechanical characteristics: increased stiffness and improved surface hardness compared with plain PLA

How to use

Load the filament into a compatible 1.75 mm extruder and set the printer to the PLA-recommended temperature range, adjusting slightly upward if needed to improve flow due to the carbon content. Use a hardened or coated nozzle to reduce wear from carbon fibers and enable consistent extrusion. Print with moderate cooling to retain part strength; bed adhesion aids such as a glue stick, PEI sheet or blue tape may be used depending on the build surface. Calibrate extrusion multiplier and retraction to reduce stringing and ensure dimensional accuracy.

Usage recommendations

For best results, use a hardened steel nozzle, set extrusion temperature within the PLA range while monitoring flow, and avoid excessive retraction speeds. Store the spool in a dry environment or sealed bag with desiccant to preserve filament quality.
