摘要：
Porous formulation storage cushion, formulation delivery systems including porous formulation storage cushions, and methods of additively manufacturing a porous formulation storage cushions are described. In an embodiment, the porous formulation storage cushion defines a plurality of pores configured to absorb a formulation, such as through wicking the formulation through capillary action. In an embodiment, the plurality of pores is configured to define a capillary force gradient along a length of the porous formulation storage cushion.

CLAIMS
The embodiments of the invention in which a property or privilege is claimed are defined as follows:
1. A formulation delivery system, comprising:
a porous applicator configured to absorb a formulation; and
a porous formulation storage cushion defining a plurality of pores configured to absorb the formulation,
wherein the plurality of pores is configured to define a capillary force gradient along a length of the porous formulation storage cushion.
2. The formulation delivery system of Claim 1, wherein the porous formulation storage cushion comprises an additively manufactured porous structure.
3. The formulation delivery system of Claim 1, wherein the porous formulation storage cushion defines a first plurality of pores and a second plurality of pores, the second plurality of pores having a pore configuration, capillary force gradient, pore density, or fluid passage density different from the first plurality of pores.
4. The formulation delivery system of Claim 1, wherein the porous formulation storage cushion is carried by a body portion of the formulation delivery system.
5. The formulation delivery system of Claim 1, wherein the porous formulation storage cushion comprises a porous sintered material.
6. The formulation delivery system of Claim 1, wherein the porous formulation storage cushion comprises a plurality of filaments, and wherein interstices between individual filaments of the plurality of filaments define the plurality of pores.
7. The formulation delivery system of Claim 6, wherein a thickness of filaments of the plurality of filaments varies along a length of the porous formulation storage cushion.
8. The formulation delivery system of Claim 6, wherein the plurality of pores defined by the plurality of filaments is configured to provide a directional wicking of the formulation through the plurality of pores.
9. The formulation delivery system of Claim 1, wherein a size of individual pores of the plurality of pores defines a pore-size gradient along a length of the porous formulation storage cushion.
10. The formulation delivery system of Claim 1, wherein a density of pores of the plurality of pores defines a pore-density gradient along a length of the porous formulation storage cushion.
11. The formulation delivery system of Claim 1, wherein an application surface of the porous storage formulation cushion defines a first portion having a plurality of pores configured to place the porous applicator in fluidic contact with the formulation and a second portion free of pores.
12. The formulation delivery system of Claim 1, further comprising a formulation carried by the body portion and in a fluidic communication with the plurality of pores.
13. The formulation delivery system of Claim 1, wherein the porous formulation storage cushion is configured to load a first portion of the porous applicator with a first amount of formulation and to load a second portion of the porous applicator with a second amount of formulation different than the first amount.
14. A method of additively manufacturing a porous formulation storage cushion defining a plurality of pores configured to absorb a formulation, the method comprising:
depositing a first layer of a material with an additive manufacturing assembly; and depositing a second layer of the material with the additive manufacturing assembly to define a plurality of pores,
wherein the plurality of pores is configured to define a capillary force gradient along a length of the porous formulation storage cushion.
15. A method of transporting a formulation, the method comprising:
transporting the formulation from a base portion of a porous formulation storage cushion through a plurality of pores to an application surface of the porous formulation storage cushion by capillary action; and
transporting the formulation from the application surface through pores of a porous applicator,
wherein the plurality of pores is configured to define a capillary force gradient along a length of the porous formulation storage cushion.
