PLA Filament 1.75 mm 1 kg for 3D printers — Riff Black CARBON

Riff PLA filament 1.75 mm — 1 kg spool in Black CARBON is a standard-diameter biodegradable thermoplastic filament formulated for FDM/FFF 3D printers. The filament is intended for general-purpose printing of prototypes, scale models and everyday functional parts. Its consistent diameter and smooth surface help maintain stable extrusion, while PLA chemistry reduces the risk of warping and simplifies bed adhesion compared with more demanding materials.

Advantages

The filament delivers reliable feeding and uniform layer deposition thanks to precise 1.75 mm diameter control and a smooth, semi-matte Black CARBON finish. It prints at conventional PLA temperature ranges and offers low odor and minimal shrinkage, which reduces part deformation and the need for an enclosed build chamber. The material is compatible with common build surfaces and adhesives used for PLA, allowing straightforward first-layer adhesion and predictable results for short to medium print durations.

Suitable for

• Rapid prototyping and concept models
• Detailed figurines and scale models
• Functional desktop parts with moderate mechanical requirements
• Educational projects and classroom printing
• Hobbyist prints and decorative objects

Key specifications

• Filament diameter: 1.75 mm nominal
• Net spool weight: 1 kg of filament
• Material: Polylactic Acid (PLA)
• Colour/finish: Black CARBON, semi-matte appearance
• Recommended nozzle diameter: 0.3–0.6 mm
• Typical print temperature range: 190–220°C (adjust per printer and model)
• Typical bed temperature: 0–60°C (often prints well on unheated beds with suitable adhesion)
• Tolerances: manufactured to tight diameter tolerance for consistent extrusion

How to use

Load the filament onto a 3D printer designed for 1.75 mm filament and confirm the spool rotates freely on the holder. Preheat the hotend to a temperature within the recommended range (start around 200°C) and purge until extrusion is consistent. Calibrate nozzle height and first-layer settings to achieve good bed contact; use common PLA print speeds and cooling fan settings to balance detail and layer adhesion. Adjust print temperature and speed for complex geometries or fine details as needed.

Usage recommendations

Store the spool in a dry environment or sealed bag with desiccant to prevent moisture absorption, which can cause bubbling and poor surface quality. For improved bed adhesion, use blue painter’s tape, a PEI sheet, glue stick or a heated bed set to the lower end of the recommended range. Avoid prolonged exposure to high temperatures and UV light to preserve material properties and colour.
