PLA 3D printer filament spool Fiberlogy Refill R 1.75 mm 0.85 kg — Anthracite

Fiberlogy Refill R PLA 1.75 mm (0.85 kg) in anthracite is a general-purpose thermoplastic filament designed for FDM desktop 3D printers. The material is intended for prototyping, visual models and hobby parts where ease of printing and dimensional stability are important. The filament diameter of 1.75 mm and consistent spool winding support reliable extrusion on a wide range of consumer and prosumer printers.

Advantages

This PLA filament provides good dimensional stability and low warping during printing, making it convenient for multi-part assemblies and models with flat surfaces. It prints well on most standard hotends at typical PLA temperature ranges and offers consistent color and finish in anthracite for neutral, technical-looking parts. The 0.85 kg spool delivers a substantial amount of material while remaining compact and easy to handle.

Suitable for

• Hobby and decorative models
• Architectural and scale prototypes
• Visual concept models and mockups
• Low-stress functional prototypes
• Educational and classroom projects

Key specifications

• Material: Polylactic Acid (PLA)
• Nominal diameter: 1.75 mm
• Net filament weight: 0.85 kg
• Color: Anthracite (dark grey)
• Compatibility: FDM/FFF desktop 3D printers with 1.75 mm filament
• Typical use: General-purpose prototyping and visual models

How to use

Load the filament onto the spool holder, feed the 1.75 mm filament into the extruder according to your printer manufacturer's instructions, and purge until the anthracite color extrudes cleanly. Use standard PLA printing temperatures typically between 190–220°C depending on your printer and hotend; adjust print speed and cooling settings to balance surface quality and layer adhesion. Bed adhesion aids such as blue painter's tape, glue stick or a PEI surface can help with first-layer stability. Store the spool in a dry place when not in use to maintain filament quality.

Usage recommendations

For best results, start with mid-range settings (nozzle 200°C, bed 50–60°C, moderate cooling) and print a small calibration cube to fine-tune extrusion multiplier and retraction. Avoid exposure to prolonged high temperatures or direct sunlight when using printed parts, as PLA has limited heat resistance compared with engineering plastics.
