Abstract
This disclosure describes multi-fluid kits for three-dimensional printing, three-dimensional printing kits, and methods of sensing metal ions using three-dimensional printed ion sensors. In one example, a multi-fluid kit for three-dimensional printing can include a fusing agent and an ion-sensing agent. The fusing agent can include water and an electromagnetic radiation absorber. The electromagnetic radiation absorber can absorb radiation energy and convert the radiation energy to heat. The ion-sensing agent can include water and a redox-active inorganic salt.
Claims14
A multi-fluid kit for three-dimensional printing, the multi-fluid kit comprising:
- a fusing agent comprising water and an electromagnetic radiation absorber, wherein the electromagnetic radiation absorber absorbs radiation energy and converts the radiation energy to heat;
- and
- an ion-sensing agent comprising:
- water;
- and
- a redox-active inorganic salt present in an amount of from about 0.5 wt % to 3 wt % with respect to a total weight of the ion-sensing agent.
A three-dimensional printing kit, comprising:
- a powder bed material comprising polymer particles;
- a fusing agent comprising water and an electromagnetic radiation absorber, wherein the electromagnetic radiation absorber absorbs electromagnetic radiation energy and converts the electromagnetic radiation energy to heat;
- and
- an ion-sensing agent comprising:
- water;
- and
- a redox-active inorganic salt present in an amount of from about 0.5 wt % to 3 wt % with respect to a total weight of the ion-sensing agent.
A method of sensing a metal ion, the method comprising:
- exposing a three-dimensional printed ion sensor having a fused polymer matrix with a redox-active inorganic salt immobilized therein to a solution comprising a target metal ion;
- and
- reacting the redox-active inorganic salt with the target metal ion during the exposing to form a water-insoluble colored pigment that colors a portion of a surface of the three-dimensional printed ion sensor, the colored portion indicating a presence of the target metal ion.
