Abstract
Three-dimensionally printed parts are exposed to different processes enabling the parts or components thereof to be reused. In one example, a 3D printed part is exposed to an absorber extraction process, and the absorber extracted from the 3D printed part is used to form a second-generation fusing agent. In another example, a 3D printed part is divided into smaller pieces and injection molded to form a second-generation 3D object with unexpectedly high mechanical properties.
Claims15
A fusing agent comprising:
- from about 10 wt % active to about 50 wt % active of a plasticizing solvent;
- from about 30 wt % active to about 50 wt % active of a water miscible co-solvent;
- and
- from about 10 wt % and about 30 wt % of an absorber extract solution,
- wherein each wt % is based on a total weight of the fusing agent.

5 more elements
A method, comprising:
- dividing a thermoplastic polyamide 3D printed object into smaller pieces;
- exposing the smaller pieces to an aqueous solution including from about 10 wt % active to about 80 wt % active of ethanol for a predetermined period of time, thereby extracting a radiation absorbing dye or a colorless ultraviolet light absorber from the thermoplastic polyamide 3D printed object;
- generating an absorber extract solution from the extracted radiation absorbing dye or colorless ultraviolet-light absorber;
- and
- formulating a second-generation fusing agent from the absorber extract solution.
