The time PVA filament takes to dissolve in water can vary based on several factors. Generally, it dissolves within a few hours, but this duration can change depending on the water temperature and the size and complexity of the support structures. Warmer water speeds up the process, while larger, denser structures might require more time. Stirring the water or breaking down the supports into smaller pieces can also accelerate dissolution.
PVA filament typically isn't recycled in the traditional sense due to its water-soluble nature. However, it's biodegradable, making it environmentally friendly. For effective disposal, PVA is best placed in industrial composting setups where it can break down properly. Home composting may not provide the necessary conditions for complete decomposition, so it's advisable to use proper disposal methods to minimize environmental impact.
PVA filament is mainly used as a support material rather than for printing entire objects. This is due to its water solubility, which can pose issues in any environment with moisture. Additionally, PVA has lower structural strength compared to other filaments like PLA or ABS, making it less suitable for creating durable, standalone objects. While it's technically possible to print entire items with PVA, they would lack the stability and longevity offered by other materials, limiting their practicality.
