PVA - Polyvinyl Alcohol
Polyvinyl Alcohol is a water soluble, bio degradable and bio compatible material found commonly in pill casings and detergent capsules. As a filament PVA is typically used as a support material in multi material systems like a tool changing FDM 3D printer due to its unique property to fully dissolve in water. How ever this ability is also a disadvantage since PVA demands to be kept in a dry environment or the entire spool could be waterlogged in a matter of minutes.
Advantages
- Water soluble.
- Can be used for casting.
Disadvantages
- Water soluble
- Not suitable for mechanical parts.
Variants
PVA filaments only come in natural coloration and do not contain fill additives such as glass fibers.
Baseline Printing Recommendations
These numbers are provided as a baseline, and need adjustment and calibration for your specific printer/filament/color combination.
| Variant | Hotend Temperature | Heatbed Temperature | Chamber Temperature | Optimistic Usable Temperature | Drying Temperature |
|---|---|---|---|---|---|
| PVA | 220 | 60 | Not required | 70 | 80 |
