3D printers that use PVA, or PolyVinyl Alcohol, as a support material require post-processing to remove it. 

The Ultimaker PVA-Removal Station PolyVinyl Alcohol is designed to remove the support material. 

This is generally achieved by dissolving the PVA for a long period of time in water. Depending on the size, complexity of the design and density of the support structure, this process can take more than a day to complete. 

The PVA-Removal Station is filled with 13.5 litres of water and its circulation direction will change automatically and the speed can be adjusted as needed. It comes with a basket and divider to fix prints and to keep them submerged. 

The saturation indicator shows if water needs changing, and the transparent container allows for a quick view on the dissolving process. PVA is a biodegradable material, and in most cases disposing the water afterwards is easy.
