Stop extruding the ASA filament after the previous material has been completely purged and cleaned out. If the printer is currently loaded with a different lower temperature material, unload that material at its recommended printing temperature, and then load and extrude your ASA filament at 240-260☌. Stop extruding the ASA filament after the previous material has been completely purged and cleaned out, lower the temperature to 240-260☌, and extrude the ASA plastic for a few more seconds.Ĭhanging from a lower temperature material: It is important to load the ASA at this higher temperature so the previous material can be pushed out. If the printer is currently loaded with a higher temperature material, unload that material at its recommended printing temperature, and then load and extrude your ASA filament at that same higher temperature. Stop extruding the ASA filament after the previous colour is completely purged.Ĭhanging from a higher temperature material: If the printer is currently loaded with ASA or a similar material, unload that material at 240-260☌ and extrude your ASA filament at the same temperature. If you typically have issues with moisture in your filament, you can read our tips and comments on filament storage to determine if a dry box will be beneficial. ASA exhibits good chemical resistance and a high temperature resistance, softening at 105˚C (Vicat softening temperature).ĪSA doesn't have any specific feeding path requirements.Īs a general tip we recommend avoiding long and complicated feeding paths that can cause bends in the filament, this can introduce drag on the filament that may result in difficulties feeding and extruding. The similarities between ABS and ASA are not surprising as these materials share two monomers acrylonitrile and styrene.ĪSA's excellent weather resistance outperforms many other plastics and can be broken down into 3 factors: UV resistance, water resistance and thermal stability.ĪSA is stronger and stiffer material than ABS and typically prints with an attractive satin finish. Contents:ĪSA (Acrylonitrile Styrene Acrylate) is an amorphous plastic that exhibits excellent weather resistance and similar characteristics to ABS (Acrylonitrile Butadiene Styrene). ASA is best suited and commonly used for automotive, household and research projects that will spend significant time in the outdoors. This user guide was last updated - 28th January 2020ĪSA is a UV and weather resistant material sharing similar printing characteristics to ABS while displaying improved strength and dimensional stability. We have highlighted important topics with a star (*) so please don't feel intimidated as sections in this guide may not be relevant to everyone, - Matt Tyson, 3D Printing Solutions This article has been written to provide both printing and troubleshooting tips along with tips for post-printing processes like painting and support removal.
