Abstract
A method of recovering fluoropolymer from a three-dimensional printed object can include dissolving a fluoropolymer of a three-dimensional printed object in a fluoropolymer-dissolving solvent to generate dissolved fluoropolymer from the three-dimensional object, wherein the three-dimensional printed object includes from about 0.1 wt % to about 10 wt % particulate fusing compound and from about 90 wt % to about 99.9 wt % fluoropolymer. The method can further include separating the particulate fusing compound from the fluoropolymer-dissolving solvent and the dissolved fluoropolymer, and evaporating the fluoropolymer-dissolving solvent from the dissolved fluoropolymer.

A method of recovering a fluoropolymer from a three-dimensional printed object, the method comprising:
- reducing the three-dimensional printed object to particles, wherein the particles include from about 0.1 wt % to about 10 wt % of a particulate fusing compound and from about 90 wt % to about 99.9 wt % of a fluoropolymer;
- dissolving the fluoropolymer of the particles in a fluoropolymer-dissolving solvent to form a solution including the fluoropolymer and the fluoropolymer-dissolving solvent, wherein the particulate fusing compound is suspended in the solution;
- separating the particulate fusing compound from the solution;
- and
- evaporating the fluoropolymer-dissolving solvent, thereby recovering the fluoropolymer from the solution.
