Various systems and methods are provided for a tunable wicking structure. In one example, the tunable wicking structure comprises a micro wicking element comprising a plurality of powder particles, each powder particle of the micro wicking element being partially joined to at least one other powder particle of the micro wicking element, and wherein a plurality of channels are formed between partially joined powder particles of the micro wicking element for drawing liquid through the micro wicking element via capillary action. The tunable wicking structure may also include a macro wicking element including a lattice structure formed by a grid of lines of material, the lattice structure including pores formed between the lines of material, in which the powder particles are disposed.
