3D Printing Filament Guide: Understanding ASA Filament The post-processing can be carried out similar to that carried out on ABS filaments. Superior UV resistance: ASA material exhibits better shape and colour retention properties, has higher durability over time, and shows exceptional weather and chemical resistance.Įasy to post-process: ASA filament is quite easy to post-process. Superior Mechanical Properties: ASA filament has a high wear and impact resistance which makes it a good alternative to ABS filament. In this 3D printing filament guide, we now will list down the properties of the ASA filament: 3D Printing Filament Guide: Properties of ASA Filament It exhibits better shape and colour retention properties, it has higher durability over time and shows exceptional weather and chemical resistance. It is easily smoothened by using acetone vapours like in the case of ABS. In the case of post-processing the ASA material, it performs similarly to an ABS filament. In such outdoor conditions, ABS turns yellowish while ASA shows higher resistance. This comes in handy when the 3D printed part has to perform in outdoor conditions like housing equipment’s, gardening tools, planters, automotive exterior parts, etc. This means it can sustain longer periods of direct sunlight. The biggest advantage of ASA is that it has higher resistance to UV. Why ASA is an alternative to ABS?ĪBS is widely used in a lot of applications due to its good mechanical properties but ASA betters these properties in almost every way. Even though ASA is quite similar to ABS, it is partially better than ABS in most of the important factors like strength, UV & water resistance.ĪSA is a thermoplastic that combines mechanical strength & UV resistance with applications in the automotive exteriors, sports goods, garden equipment & housings or other outdoor components. Being thermoplastic, it can be heated to their melting point, cooled, and re-heated again without significant degradation. It is widely considered as an alternative to ABS filament.
