ASA C-Tech filaments are ideal for users who need a strong, UV-stable, and heat-resistant material for printing functional and structural parts. ASA (Acrylonitrile Styrene Acrylate) is a modern polymer similar to ABS filament, but with better resistance to weather conditions and UV radiation, thanks to which prints retain their color, strength, and shape for a long time, even when used outdoors.
Filaments of the C-Tech brand are manufactured with an emphasis on consistent diameter, smooth flow, and easy printability, enabling stable printing even of more complex models without layer cracking or warping.





C-Tech ASA is an excellent choice for technical components, enclosures, holders, infills, signage, or prototypes exposed to outdoor conditions.
Thanks to its structure, the material is resistant to UV radiation, rain, and frost, making it an excellent choice for outdoor use. Prints made from ASA filament have a smooth, professional surface and excellent layer adhesion, so they look aesthetically pleasing while also withstanding mechanical stress.Main advantages of C-Tech ASA filaments:
High UV resistance and color stability – suitable for outdoor applications
Heat resistance up to approx. 100 °C
Less shrinkage than ABS, so it prints more stably
Strength, stiffness, and toughness for mechanically stressed parts
Resistance to weather conditions, moisture, and chemicals
Surface finishing options (sanding, acetone smoothing)
The C-Tech ASA filaments are designed to be easy to process even on standard desktop 3D printers with a heated bed. Recommended printing temperatures range between 240–260 °C, and the print bed should be at least 90–110 °C. Even without an enclosed print chamber, it is possible to achieve minimal warping and excellent layer adhesion. In addition, after printing, the material retains high dimensional stability even when exposed to heat or sunlight for extended periods.
In our offer, you will find C-Tech ASA filaments in a wide selection of colors and formats – from neutral shades for technical prints to vivid colors suitable for visually attractive models.
Available are standard spools as well as refill variants without a spool, which represent an eco-friendly solution for users who want to print sustainably while also saving space and reducing waste.C-Tech ASA filament combines durability, precision, and ease of printing, making it a great material for those who want a professional result without complicated printer setup. Prints made from ASA retain color stability, strength, and dimensional accuracy, even in demanding operating conditions.
The C-Tech ASA Filaments category offers a reliable and high-quality solution for users who require functional, durable, and aesthetically clean prints. This material is suitable both for technical and industrial use and for long-term outdoor applications, where resistance to sunlight, heat, and weather conditions is required.
