  • Recycle feedstocks for on-demand article manufacturing
    Patent number: 11649337
    Abstract: A method of recycling a polymer structure includes converting a first polymer structure into feedstock. The first polymer structure comprises particles that are bonded to one another by chemical click bonds to form a first shape. The first polymer structure is converted into feedstock particles by breaking the click bonds. The feedstock particles are formed into a second shape, and the feedstock particles are chemically click-bonded together to form a second polymer structure having a second shape. Breaking the click bonds may include heating the particles. The structures may be formed by causing first particles having dienes to chemically bond to dienophiles of second particles.
