3D printer filament eSun EPLA-CF 1.75mm Red 1kg — PLA composite carbon-filled

eSun EPLA-CF 1.75mm Red is a 1 kg spool of PLA-based carbon-filled 3D printer filament formulated for standard 1.75 mm extruders. This composite PLA combines the printability and low-warp characteristics of PLA with short carbon fibers to produce a matte, textured surface and increased stiffness compared with conventional PLA. The material is intended for users who need improved dimensional stability and a more industrial look for prototypes, functional parts and consumer items.

Advantages

The carbon-filled PLA offers higher rigidity and a more pronounced matte finish than regular PLA, reducing visible layer lines and improving the perceived surface quality. It retains PLA’s ease of printing, including low warping and good bed adhesion in most desktop FDM setups. The filament’s composition allows for stronger lightweight parts and improved resistance to bending while maintaining compatibility with common 1.75 mm extrusion systems.

Suitable for

• Prototyping functional parts that require increased stiffness
• Aesthetic prints requiring a matte, textured surface
• Lightweight mechanical components, brackets and housings
• Desktop FDM printers with 1.75 mm filament support

When it may not be suitable

Because the filament contains short carbon fibers, it is more abrasive than standard PLA and may accelerate wear on brass nozzles; hardened or coated nozzles are recommended for extended use. The material can be more brittle than pure PLA, so parts requiring high impact resistance or high elongation may perform worse than those printed in ductile materials like ABS or PETG.

Key specifications

• Filament diameter: 1.75 mm
• Spool weight: 1 kg
• Base material: PLA composite with carbon fiber filler
• Color and finish: Red with matte, textured surface
• Recommended extruder type: Standard 1.75 mm FDM extruders

How to use

Load the filament into a 1.75 mm-compatible FDM printer using a clean, properly calibrated extruder. Typical print temperatures for PLA-based composites are slightly higher than for pure PLA; start with manufacturer-recommended ranges for carbon-filled PLA and fine-tune between 200–230 °C depending on your printer and nozzle. Use a heated bed set to typical PLA values (around 40–60 °C) or build surfaces that offer good adhesion. Print slower than pure PLA if needed to allow consistent extrusion; adjust fan cooling to achieve the desired surface texture and layer bonding.

What to consider before purchase

• Printer compatibility with 1.75 mm filament and available nozzle materials
• Potential nozzle wear due to carbon fiber abrasiveness
• Desired mechanical properties — increased stiffness but lower impact resistance than some alternatives
• Color and surface finish requirements for final parts

Usage recommendations

For best results use a hardened steel or coated nozzle, calibrate extrusion and temperature settings, and print slower than standard PLA to reduce jamming. Allow parts to cool gradually to minimise internal stresses and use common PLA bed temperatures for reliable adhesion.
