Zortrax Z-SUPPORT ATP is a soluble support filament, good to use as support for Z-ULTRAT, Z-ULTRAT Plus, Z-ABS and Z-ASA Pro. It enables the production of complex, detailed models in one go. Unlike PVA and BVOH-based materials, Z-SUPPORT ATP does not dissolve in water, but in a mild alkaline solution containing Z-SUPPORT ATP Activator. As a result, it absorbs much less moisture. As a result, the material is much less sensitive to ambient moisture. Z-SUPPORT ATP leaves no traces on the model. Models printed with it must be finished in a heated, stirred bath at 80°C.
