For models that include a support structure, you should remove the support structure from the print.
If you use a PVA filament to print supports, you can dissolve the PVA with warm water. The dissolution process may take several hours.
Manually remove part of the support structures that is easier to peel off.
Immerse the print in warm water and the PVA filaments will slowly dissolve. The dissolution process can be accelerated by using warmer water or changing the water regularly.
When PVA and PLA filaments are used for printing at the same time, do not soak the print in hot water higher than 50℃, or the PLA may be deformed due to heat. This temperature value is for reference only. It is recommended to consult the information provided by the PLA filament manufacturer for detailed guidance.
After the PVA support is completely dissolved, rinse the print thoroughly with clean water to remove the remaining PVA.
Dry the print.
Waste water treatment.
Wastewater containing PVA solution may require special treatment. Refer to the literature provided by the PVA filament manufacturer or consult your local wastewater (sewage) disposal authority for more comprehensive guidance.
You can remove supports manually with the help of the following tools. When removing, carefully control the force and direction to avoid being scratched by sharp structures in tools or prints.
Diagonal Pliers
Provided, see tool box. Diagonal pliers with wide jaws are often used to remove support structures at the periphery, but are less suitable for removing structures embedded deep in the print.
Needle-nose Pliers
Not provided. Long, narrow needle-nose pliers can penetrate deep into the print, but are less suitable for removing finer structures.
Carving Knife
Not provided. The carving knife has a sharp edge and can be used to cut small structures that require precise control.
To prevent cuts, be careful when using a carving knife. It is recommended to wear protective gloves.
