Filament eSun EABS-CF 1.75 mm DARK PURPLE 1 kg — ABS-CF composite filament for FDM/FFF printers

eSun EABS-CF 1.75 mm DARK PURPLE is a 1 kg spool of ABS-based composite filament reinforced with short carbon fibers for FDM/FFF 3D printers. Supplied in 1.75 mm diameter, this dark purple filament is formulated to deliver higher stiffness and improved dimensional stability compared with standard ABS. It is suitable for functional prototypes and end-use parts that require greater mechanical strength and elevated temperature resistance while maintaining compatibility with common ABS printing profiles.

Advantages

Combining ABS polymer with dispersed carbon fibers increases tensile stiffness, reduces warping and improves dimensional accuracy in printed parts. The filament offers enhanced heat resistance relative to standard PLA and can withstand higher operating temperatures typical for ABS-based materials. The 1.75 mm diameter ensures compatibility with a wide range of desktop FDM/FFF extruders designed for ABS-type filaments.

Suitable for

• Functional prototypes and mechanical components requiring rigidity
• Jigs, fixtures and tooling aids used in workshop environments
• End-use parts exposed to elevated temperatures or mechanical load
• Housings and structural elements where dimensional stability is important

Key specifications

• Material: ABS composite reinforced with short carbon fibers
• Filament diameter: 1.75 mm
• Net weight: 1 kg spool
• Color: dark purple
• Compatibility: FDM/FFF desktop 3D printers that accept 1.75 mm ABS-type filaments

How to use

Load the filament into a 3D printer equipped to handle ABS composites and set extrusion temperature according to ABS printing guidelines, adjusting within the manufacturer’s recommended range for ABS-CF if provided by the printer or filament supplier. Use a heated bed to reduce warping and enhance adhesion; a brim or raft may be used for larger parts. Moderate print speeds and adequate cooling settings for ABS composites will help achieve consistent extrusion and layer bonding. Post-processing such as sanding or trimming can be performed with appropriate tools for composite materials.

Usage recommendations

Store the filament in a dry, airtight container or vacuum bag with desiccant to minimize moisture uptake. Use a hardened steel or coated nozzle to resist abrasion from carbon fibers and inspect extruder gear and feed path for wear. For best dimensional results, calibrate extrusion multiplier and bed leveling before printing critical parts.
