3D printer filament c-tech PREMIUM LINE ASA Traffic Black RAL9017 1.75mm 1kg

c-tech PREMIUM LINE ASA filament in Traffic Black RAL9017 is a 1.75 mm, 1 kg spool formulated for fused filament fabrication (FFF) 3D printers. This ASA material provides greater weather and UV resistance compared to standard ABS, making it suitable for outdoor parts and functional prototypes. The filament is intended for users who require improved dimensional stability, mechanical strength and surface finish for technical applications such as housings, trims and mounts.

Advantages

The Premium Line ASA offers consistent diameter tolerance and good layer adhesion for reliable printing. Its composition improves resistance to sunlight, rain and temperature fluctuations, reducing yellowing and degradation over time. The Traffic Black color (RAL9017) delivers a deep, uniform black finish that is suitable for visible functional components. The 1.75 mm format on a 1 kg spool is compatible with a wide range of consumer and professional FFF printers.

Suitable for

• Outdoor housings and enclosures
• Automotive trims and interior fixtures
• Functional prototypes and end-use parts
• Mechanical brackets, mounts and fixtures
• Parts requiring UV and weather resistance

Key specifications

• Material: ASA (Acrylonitrile Styrene Acrylate)
• Color: Traffic Black (RAL9017)
• Diameter: 1.75 mm
• Spool weight: 1 kg
• Recommended printing method: FFF / FDM
• Properties: UV and weather resistant, good dimensional stability

How to use

Load the 1.75 mm filament into a compatible FFF/FDM 3D printer according to the printer manufacturer's filament loading procedure. Recommended print settings typically include a nozzle temperature in the range suitable for ASA (consult your printer and material guidance for exact values), a heated bed to reduce warping, and adequate part cooling adjustments to achieve optimal layer bonding and surface quality. Use an enclosed build chamber where possible to maintain stable ambient temperature and reduce the risk of delamination.

Usage recommendations

For best results, store the filament in a dry environment or sealed packaging with desiccant to prevent moisture uptake. When printing outdoor-exposed parts, consider post-processing options such as annealing or surface sealing to further enhance dimensional stability and weather resistance. Test print critical components first to fine-tune temperature, speed and cooling settings for your specific printer.
