Description
PVA
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.

Notes:
1. Suggest to dry the material before printing (45℃/＞10H) to get perfect printing effect. It is recommended to work with eBOX(3D filament dryer) in printing.
2. It is recommended to set the distance between the support and the model to 0, Slow down and turn off the fan for the first layer to bond well with the main material.
