eSun Natural PVA Filament





  • Overview

    Print intricate designs with overhangs, internal structures and other difficult geometries that you have not been able to print before. Once printed, our water-soluble filament will dissolve away after soaking, leaving your model clean, and intact with very little clean up


    • Great for interior cavities and intricate parts that make removing support by hand difficult. PVA filament is mildly flexible at room temperature, making support material removal easier. When 3D printed it leaves no residue on the bottom surface of the part
    • It sticks well to painters tape, and less well to PET
    • When used as support material with a Dual Extruder you do not need to use a specific slicing profile. A slicing profile is available that can be used for printing entire models out of our water-soluble PVA filament

    Product Notice

    Disposal Notice

    The preferred method of disposal for polyvinyl alcohol (PVA) support material is in the trash. The immersion of 3D printed objects into water containing support material will generate wastewater containing PVA. When PVA-based support material cannot be physically removed from the object, requiring that the object be immersed in water, it is suggested that you contact your local Sanitary Sewer (Wastewater) Authority to obtain the proper disposal method prior to discharging to the sewer.

    Usage Alert

    Since PVA filament dissolves in water it may not be suitable for most parts. The filament must be stored with a drying agent, since it will absorb moisture out of the air.

    Extrusion Temperature Limit

    Do not use PVA filament at hot end temperatures over 200 °C as the material can potentially crystallize/carbonize, leading to extrusion difficulties.
