PVA is a water-soluble material that is often used as a support material with no need of adding any chemical and special treating. eave the part in a warm water bath dissolve faster. After dissolution, there is no residue on the model surface with smoothy efect; it can be worked with PLA, TPU, PA(nylon) and other consumables materials to print extremely complex shapes or support materials with a partially closed cavity model. lt's also a good choice to work for multi-nozzle printers.

eSUN Water Soluble PVA Filament 1.75mm, 3D Printer Filament PVA, 0.5KG Spool 3D Printing Filament for 3D Printers, Natural

【Water Soluble PVA】Water-soluble Polymer. Excellent Water Solubility. Easy to Peel off, Will not Damage Printed Surface. Good Bonding to Various Material Such as PLA. Environmental-friendly and Non-toxic. Ideal for Complex Prints!

【Stable Dimensional Tolerance】

【Tangle Free & No Plugging】

【Support Material】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.

【Vacuumed Sealed Packaging】0.5KG Spool Water Soluble PVA Filament comes in a sealed vacuum bag with a desiccant bag, easily keep your 3D printer filaments at an optimal storage condition and free from dust or dirt before opening the vacuumed sealed packaging.

  • Good bonding to various material such as PLA, ABS, Nylon, etc.
  • It makes it possible to print complex models and mobile constructions.

PVA Filament Print Parameter:

  • Thanks to its solubility in water,it is ideal as a support material, since thesupport structures can be washed away by water.
  • A dissolution of the material at a water temperature of 21°C takes several hours. The dissolution time can be significantly reduced by increasing the temperature.

PVA Filament Print Parameter:

  • Printing Temperature: 180-230℃(Recommend 190℃)
  • Bed Temperature: 45-60℃
  • Density: 1.25g/cm³
  • Tensile Strength: 22MPa
  • Elongation at Break: 360%

Why Need Support Material 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 Manual
  • Easily keep your 3D printer filaments at an optimal storage condition and free from dust or dirt before opening the vacuumed sealed packaging.

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.
