The Water-soluble filament is conveniently stored within an easy-to-use cartridge & uses a chip that enables you to keep track of how much filament the spool has left. Removing support material by h&, tools, or solutions can be tedious & they do not always provide the best results. The Water-soluble filament is sturdy enough to provide excellent support for your PLA prints & dissolves well enough that it does not damage the print.

Please make sure to download the latest firmware & software for your 3D printer & XYZware. 1. A separate extruder is needed before installing the Water-soluble filament. An extruder with ABS filament residue may cause the Water-soluble filament to clog. Conversely, an extruder with Water-soluble filament residue may cause ABS filament installed to clog as well. 2. XYZprinting Water-soluble filament can only be used with PLA (do NOT attempt to use with ABS). 3. The Water-soluble filament absorbs water fairly quickly, so it must be stored in low-moisture environments (Moisture 30&65285; RH) in order to improve its longevity. 4. To increase the success rate of loading the filament, please insert the Water-soluble filament into the guide tube until the material has reached the drive gear, grasp the release arm, & push the filament downward slightly (about 1 to 2 cm). Once it is inserted, let go of the release arm & run "LOAD FILAMENT."
