Abstract
A method of recycling and reusing a tap water-soluble sulfonated polymer material from a structural component made using an additive manufacturing process comprises dissolving the structural component in water to disperse the sulfonated polymer material into the water. The sulfonated polymer material is precipitated from the water and recovered; then dried and reformed into a form suitable for subsequent use as a consumable feedstock in a subsequent additive manufacturing process.
