  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.

  一种回收和再利用自来水溶性磺化聚合物材料的方法，该材料来自使用添加剂制造工艺制造的结构组件，该方法包括将结构组件溶解在水中，使磺化聚合物材料分散到水中。磺化聚合物材料从水中析出并回收；然后干燥并重整成适合随后用作后续添加剂制造工艺中的消耗原料的形式。
