“…[13,23] In addition, additive manufacturing has great potential for upscaling as the manufacturing can be parallelized and combined with the electrochemical reactor design by e.g., multi-material 3D printing. [23,24] Several additive manufacturing techniques have been employed to fabricate electrodes for electrochemical devices [5,24,25] including material jetting, [26] material extrusion, [13,[27][28][29][30][31][32] powder bed fusion, [33,34] VAT photopolymerization (i.e., stereolithography (SLA), [22,35,36] digital light processing [37,38] ), and two-photon polymerization. [39] The choice of precursor (e.g., metals, plastics, composites, inorganics [24] ) and the manufacturing method control the structural properties of the electrode comprising the feature size, geometry, porosity, size, surface roughness, and mechanical stability, as well as the manufacturing time.…”
