About this material
Like ABS, ASA is a very robust plastic which, in addition to its excellent material properties, also has a high-quality appearance. Unlike some other plastics, ASA is suitable for outdoor use as it is UV-stable. Compared to the widely used PLA and PETG, processing it is much more labour-intensive for my printer farm.
Depending on the product, I rely on two leading brands for ASA.
Prusament
… valued for its years of reliability
PolyMaker
.. valued for its colour range and the lower environmental footprint of its packaging
I use these relatively expensive filaments because I can rely on them and the cost of the filament plays a very minor role in the product price. Moreover, cheaper filaments have not performed very well in my own tests.
