3D-scaffolds can be obtained by overlaying the individual lattice layers. The pore network is staggered between each consecutive layer to attain interconnected porosity. The registration of the stagger pattern is accounted for during the CNC based machining of the electrode system. A) 3D-interconnected porosity can be attained by overlaying multiple layers while staggering the pore structure. Blue and black ‘ ★ ’ denote the two separate scaffold layers. B) Layers can be patterned as parallel channel to induce collagen molecule alignment and make desired pore shaped scaffolds by staggering the individual layers.
