A method of recycling a water dispersible sulfonated polymer material used as a support structure in an additive manufacturing process includes providing a tap water bath and placing a printed part having an adhered support structure into the tap water bath, the support structure comprising a water-soluble sulfonated polymer material. The method includes dissolving the sulfonated polymer material in the water bath to thereby create a dispersion, and modifying the ionic strength of the dispersion by adding a multivalent metal salt to the dispersion at a concentration of between 1 gram/L and 30 grams/L, to precipitate the dissolved sulfonated polymer material from the water. The method includes recovering the precipitated sulfonated polymer material from the water, drying the recovered sulfonated polymer material and reforming the dried sulfonated polymer material into a form suitable for subsequent use as a consumable feedstock in an additive manufacturing process.
