Get ready to print like you have never printed before! This filament has been the best PVA I have tried in a long time. I have struggled in the past with other brands of PVA. I have had issues with stringing, and adhesion to the bed, along with bonding to itself, BUT not with this filament. I literally took this filament out of the package, and stuck it in my printer and hit print. I am impressed at how easily this filament flows out of the nozzle with no clogging issues. I did not experience any stringing even at higher temperatures. The adhesion the the bed is perfect. The layer bonding is perfect, and best of all, the PVA filament dissolves quickly in warm moving water. for best results, I would suggest getting a large tub, fill it with warm water and put the tub on your build plate. turn your bed temp to 30-40c and run a gcode moving your bed back and forth smoothy, slightly agitating the water while keeping it warm. filament diameter is 1.75mm consistent with a dimensional accuracy of + / - 0.02 mm. I was surprised to see that this filament is packaged professionally, within a sealed bag with desiccant pouches. complex models and mobile constructions that no longer need to be assembled from individual parts. Simply wash away the support structure by immersing the model in water. The recommended temperature for printing is 230-240c. I Printed my test model at 235c which cam out perfect. Tip for storage: If you plan on not printing with this filament for a long period of time, you should seal it up in a bag to keep it free from moisture. If you need to dry the filament, do so at 50-55c for 6-8 hours. I really enjoyed using this filament, and I will be happy to purchase more in the near future :-)
