3D printer filament c-tech PLA Traffic Black RAL9017 1.75 mm 1 kg

c-tech PREMIUM LINE PLA filament in Traffic Black (RAL9017) is a 1.75 mm, 1 kg spool designed for FDM/FFF 3D printers. Made from PLA, the filament provides straightforward extrusion, consistent layer adhesion and stable dimensions suitable for prototyping, hobby modelling and functional household parts. The deep black color delivers a neutral, uniform finish that works well with both visible and internal components. The filament is supplied on a standard-sized spool compatible with most desktop 3D printers using 1.75 mm filament.

Advantages

The PLA formulation ensures easy printability at typical PLA temperatures, reduced warping compared with many engineering polymers and predictable cooling behavior. Consistent diameter tolerance supports reliable extrusion and accurate part dimensions. The Traffic Black color (RAL9017) offers strong visual contrast and conceals minor surface imperfections, while the 1 kg spool provides an economical amount of material for a range of small to medium projects.

Suitable for

• Rapid prototyping and concept models
• Hobbyist and desktop 3D printing projects
• Display models, figurines and architectural mock-ups
• Non-load-bearing household parts and fixtures
• Educational and classroom printing tasks

Key specifications

• Material: Polylactic Acid (PLA)
• Color: Traffic Black (RAL9017)
• Diameter: 1.75 mm nominal
• Spool weight: 1 kg net filament
• Spool compatibility: Standard desktop FDM/FFF printers using 1.75 mm filament

How to use

Load the 1.75 mm filament onto your printer according to the machine manufacturer’s instructions. Typical print temperatures for PLA are in the 190–220 °C range; adjust within this range to match your specific printer and nozzle. Use a heated bed set between 40–60 °C or print on a suitable adhesion surface for best first-layer bonding. Fine-tune print speed and cooling settings to achieve the desired surface quality and dimensional accuracy. Store the spool in a dry place or sealed container with desiccant to maintain filament performance.

Usage recommendations

For consistent results, calibrate extrusion multiplier and flow rate after loading a new spool and run a small test print before committing to larger parts. When printing glossy or highly detailed models, lower layer heights and increased cooling can improve surface finish; for stronger interlayer adhesion use slightly higher temperatures within the PLA range.
