PVA is a water-soluble material that is often used as a support material with no need of adding any chemical and speicial treating. Leave the part in a warm water bath dissolve faster. After dissolution, there is no residue on the model surface with smoothy effect; it can be worked with PLA, TPU, PA(nylon) and other consumables materials to print extremely complex shapes or support materials with a partially closed cavity model. It’s also a good choice to work for multi-nozzle printers.
