Abstract
A method of making an ink for use in additive manufacturing of a self-healing product includes providing a thiol material. The method further includes oxidizing the thiol material to form a thiol-disulfide oligomer. The method further includes applying an alkene material to the thiol-disulfide oligomer to allow a thiol-ene reaction and form a self-healing ink embedded with a disulfide bond.
Claims20
A method of making an ink for use in additive manufacturing of a self-healing product, the method comprising:
- providing a thiol material;
- oxidizing the thiol material to form a thiol-disulfide oligomer;
- and
- applying an alkene material to the thiol-disulfide oligomer to allow a thiol-ene reaction and form a self-healing ink embedded with a disulfide bond.
A method of making an ink for use in additive manufacturing of a self-healing product, the method comprising:
- forming a thiol material by mixing iodonium salts with toluene;
- oxidizing the thiol material to form a thiol-disulfide oligomer;
- and
- applying at least one of a photoinitiator or a photoabsorber to the thiol-disulfide oligomer to allow a thiol-ene reaction and form a self-healing ink embedded with a disulfide bond.
A method of additive manufacturing a self-healing product using a self-healing ink, the method comprising:
- creating or obtaining a computer-aided-design (CAD) model of a biphase composite;
- splitting the CAD model into two models with respective phases;
- slicing each of the two models into an image sequence with a prescribed spacing along a vertical direction;
- sequentially projecting the image sequence onto a resin bath filled with the self-healing ink;
- and
- exposing the self-healing ink to image light to solidify the self-healing ink to form a layer structure bonded to a printing stage.
