0.5kg, 1.75mm FF Filament - PVA Support
This material is water soluble, making it absolutely invaluable as a support structure for 3D printers that work with multiple materials. Simply use this filament as the support material when printing an incredibly complicated 3D object, then place the object in water for 24 hours while occasionally agitating it to have the support structures simply melt away!
PVA filament works very well with lower temperature materials, as it naturally wants to print with a nozzle between 190 and 220 degrees, as well has being happy to work without a heated bed. PVA will very easily bake if left too long at a high temperature, so we’ve found it incredibly important that whatever nozzle it is loaded into semi-unloads itself whenever the PVA is not in use. Often this can be achieved by setting the retraction to a very high value (not so high as to have it retract past the extruder gear, which would make re-loading impossible).
PVA likes to absorb the water in it’s environment, like, a lot. Once a PVA roll is opened, either the PVA needs to be used quickly, or when not in use, it should be stored in a plastic resealable bag (or other airtight environment) with the silica gel sachet that came with the roll initially to ensure the filament will last a long time in storage.
These spools will fit on nearly every 3D printer, having a large inner spool diameter, while still being quite thin and petite. We have yet to find a printer it doesn't happily sit in.
