PVA

PVA is a water-soluble material that is often used as a carrier material without any chemical or special treatment. Let the part dissolve faster in a warm water bath. After dissolving, there is no residue on the model surface with a smooth effect; it can be processed with PLA, TPU, PA(nylon) and other consumables to print extremely complex shapes or supporting materials with a partially closed cavity model. It is also a good choice to work with printers with multiple nozzles.
