eSUN 1.75mm Water Soluble PVA 3D Printer Filament - High Precision +/-0.05mm, 0.5KG (1.1LB) Spool - Ideal Support Material for Dual Extrusion 3D Printing - Perfect for Complex Models, Dissolves Easily in Water

What is Water Soluble PVA Material? PVA is a water-soluble polymer, good water solubility. Easy to peel off, will not damage printed surface. It has good bonding to various material such as PLA. Ideal for complex prints! Thanks to its solubility in water, makes it possible to print 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. Water Soluble PVA Physical Parameter: Density: 1.25g/cm³Tensile Strength: 22MPaElongation at Break: 360% Recommended Printing Parameters: Printing Temperature: 180-230℃ (Recommended Temperature 190℃)Bed Temperature: 45-60°CFan Speed: 100%Printing Speed: 20-50mm/sRecommended Heated Build Platform: Textured Paper, PEI Why is Support Material Needed in 3D Printing? If you have a printer with two extruders, you can load one extruder with PLA for printing the model and the other one with a water-soluble material like PVA or limonene soluble material like HIPS for printing the support structure. Once printing is over, simply wash away the support structure by immersing the model in water or Limonene. This method of removal reduces the risk of model damage and makes the post-processing work easier. Ideal for complex prints! Support structures are a necessary evil in 3D printing. You need them to print difficult overhangs and bridges in your model. Vacuumed Sealed Packaging: Antioxidants + Vacuum Packaging + Product ManualeSUN filament comes in a sealed vacuum bag with desiccant bag, easily keep your 3D printer filament at an optimal storage condition and free from dust or dirt. How to Storage: 1. If you are going to leave your printer inactive for more than a couple of days, please retract the filament to protect your printer nozzle.2. In order to extend the life of your filament, please place the unsealing filament back to original vacuum bag and stock it in a cool and dry place after print.3. When storing your filament, please feed the loose end through the holes on the edge of the filament reel to avoid winding, so that it feeds properly when you use it next time.
