PVA Pro filament from 123-3D.ie dissolves completely in (cold or warm) water after 3D printing. That means you can effortlessly remove support print layers. PVA Pro has all the benefits of standard PVA, plus better thermal stability and improved adhesion to PLA, ABS and PETG. With PVA Pro you get the most out of your dual extruder Ultimaker 3D printer.
