Hydrosupport is a pva filament, a soluble support filament that is dissolvable in water. It is great for printing complex shapes with overhangs, bridges and intricate inner geometry as you can use it as a solid infill and then simply wash away in water. Of itself, it has a high tensile strength and feels like PLA filament.
How to use Hydrosupport PVA filament
To use HydroSupport dissolvable filament simply soak for a few hours, the supports can then be easily removed by hand. Alternatively, soak for 12 – 24 hours and the soluble support filament will dissolve completely. You can speed this process up using a heated ultrasonic tank or by using warm water and agitating the water by hand.
HydroSupport is non-toxic, washing it away down the drain will not harm the environment or wildlife.
NOTE: Because HydroSupport breaks down in water, it is sensitive to high levels of humidity in the air. For best results store unused HydroSupport filament in a sealed container with desiccant.
