Abstract
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.
