This study investigates the 3D extrusion printing of a carboxymethyl cellulose (CMC)-gelatin complex coacervate system. Various CMC-gelatin hydrogels were prepared and analyzed to achieve this goal. The impact ratio, pH, total biopolymer concentration on coacervation formation rheological properties was evaluated characterize printability samples. Turbidity results indicated that molecular interactions between gelatin CMC biopolymers are significantly pH-dependent, occurring within range pH 3.7 5.6 for tested compositions. Confocal Laser Scanning Microscopy (CLSM) confirmed presence coacervates as spherical particles optimal range. electron microscopy micrographs supported CLSM findings, revealing greater porosity Rheological characterization demonstrated all exhibited pseudoplastic behavior, with an inverse correlation increased decreased shear viscosity.

Many tissues exhibit structural anisotropy, which imparts orientation-specific properties and functions. However, recapitulating the cellular patterns found in anisotropic presents a remarkable challenge, particularly when using soft wet hydrogels. Herein, we develop self-assembled magnetic Fe3O4 micropatterns on polyethylene glycol hydrogels utilizing dipole–dipole interactions. Under influence of static field, nanoparticles align into highly ordered structures with height 400–600 nm width 8–10 μm. Furthermore, our layer-by-layer assembly technique enables creation oriented varying densities heights, can be further manipulated to form three-dimensional by adjusting angle field.
