PVA: A Brief Introduction
PVA is a water-soluble material that is often used as a support material with no need to add any chemicals or special treatment. Leave the part in a warm water bath to dissolve faster. After dissolution, there is no residue on the model surface with a smooth effect; it can be worked with PLA, TPU, PA(nylon), and other consumable 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.
