ASA filaments (Acrylonitrile Styrene Acrylate) are a modern alternative to ABS filaments, standing out especially for their resistance to UV radiation, heat, and weather conditions. Thanks to these properties, they are ideal for manufacturing functional parts intended for long-term outdoor use, such as covers, brackets, housings, automotive components, or garden elements.
Unlike classic ABS filament, ASA has lower susceptibility to deformation (warping) and behaves more stably during printing, which will be appreciated even by less experienced users. The result is dimensionally accurate, strong, and durable prints with excellent surface quality.

ASA combines high mechanical strength with excellent resistance to outdoor conditions, which is why it is often used where other materials eventually fade or crack. Its chemical composition ensures color stability even after long-term exposure to sunlight and at the same time enables precise printing without significant shrinkage.
Key properties of ASA:
UV stability and color fastness – ideal for outdoor use
High mechanical strength and stiffness
Heat resistance up to 95–100 °C
Low warping and better printability than ABS
Resistance to moisture, chemicals, and temperature fluctuations
Possibility of post-processing – sanding, drilling, polishing with acetone
ASA filaments are suitable for technical models, structural prototypes, electronic enclosures, outdoor signage, or automotive components. Thanks to their resistance to sunlight and rain, they are popular in applications where long service life and color stability are essential.
Printing is similar to ABS – a heated bed (approx. 90–110 °C) and a nozzle temperature around 240–260 °C are recommended. ASA also has a lower tendency to deform, making it easier to work with even without an enclosed print chamber.
The range includes ASA filaments from trusted manufacturers such as Spectrum, Verbatim, C-Tech, and Gembird, in many color variants – from technical shades (black, grey, white) to bold design colors. The filaments are available in the classic version on a spool as well as in an eco-friendly refill version without a spool, which is more environmentally friendly.
Better resistance to UV radiation and weather
Lower shrinkage during printing and higher dimensional stability
Longer service life in outdoor applications
Mechanical properties comparable to ABS
Suitable for functional parts as well as design prints
If you need a material that can withstand high temperatures, sun, and rain, ASA filaments are the ideal choice. They offer a combination of industrial-grade durability, aesthetic appearance, and easy printability, which has made them a popular solution for technical and outdoor 3D prints.
The ASA Filaments category offers a wide selection of high-quality materials with excellent resistance to UV radiation and weather conditions. It is a great choice for everyone who wants prints with long service life, stable dimensions, and a professional appearance – whether for technical applications or permanent outdoor use.
