I'm working with a 3D printer that uses PVA filament as a support material. After a 3D printed part is made, it is put in water for some time to dissolve away the PVA supports.
I'm trying to speed up the process by using a heated magnetic stirring plate with a pump connected to a filter. The filter is for removing the already dissolved PVA from the water solution so that the solution doesn't get saturated.
I plan on using a 2L container of water and heating it to about 60-80 degrees C. There would be about 10-50 grams of PVA being dissolved at a time.
I have two main questions:
- What kind of filter(s) could I use for PVA in a water solution?
- Do I really need a filter? I.e. would 50 g of PVA have issues dissolving in 2L of 80C water?
