3D Printer ABS Filament Renkforce RF-6838912 1.75 mm 1 kg Black (RAL 7001)

Renkforce ABS filament RF-6838912 is a 1.75 mm diameter thermoplastic spool designed for FDM/FFF 3D printers. Supplied on a 1 kg spool in black (RAL 7001), this ABS material combines good tensile strength with moderate flexibility, making it suitable for functional prototypes, mechanical parts and some end-use components. The filament is intended for printers that accept 1.75 mm ABS and is compatible with standard ABS printing workflows that use a heated bed and controlled extrusion temperatures.

Advantages

This ABS filament provides consistent diameter and reliable extrusion for stable print quality. Its material properties offer impact resistance and dimensional stability after cooling, which helps parts retain shape under load. The black (RAL 7001) color delivers an even, matte finish suitable for visible components and functional assemblies. The 1 kg spool format is convenient for iterative prototyping and small production runs.

Suitable for

• Functional prototypes and proof-of-concept models
• Mechanical components and brackets
• End-use parts requiring moderate strength and impact resistance
• Parts that require post-processing such as sanding or smoothing

Key specifications

• Material: ABS (acrylonitrile butadiene styrene)
• Diameter: 1.75 mm
• Spool weight: 1 kg
• Color: Black (RAL 7001)
• Compatibility: FDM/FFF 3D printers that accept 1.75 mm ABS filament

How to use

Load the 1.75 mm filament into a printer compatible with ABS. Set the extruder temperature according to your printer manufacturer’s recommendations for ABS (typical range 220–250 °C) and use a heated bed to reduce warping (typical bed temperature 80–110 °C). Ensure proper bed adhesion using a suitable build surface or adhesion aid. Print speeds, retraction and cooling settings should be adjusted based on part geometry and printer characteristics. After printing, allow parts to cool gradually to minimise dimensional changes prior to removal from the build plate.

Usage recommendations

For best results, use a heated enclosure or minimise drafts to reduce warping and layer adhesion issues. Apply a consistent bed preparation method (PEI, Kapton tape or adhesive) and calibrate extrusion flow and bed leveling before starting long prints. Post-processing such as sanding, acetone smoothing (with suitable safety precautions), or annealing can improve surface finish and mechanical properties.
