Abstract Two vat polymerization techniques were evaluated to print innovative hydrogel scaffolds for tissue engineering, from aqueous photo-crosslinkable formulations based on methacrylated carboxymethylcellulose (mCMC). A first formulation containing 2 wt% mCMC with a methacrylation degree (DM) of 34% and lithium phenyl-2,4,6-trimethylbenzoylphosphinate (LAP) as photoinitiator was specifically developed digital light processing (DLP). Considering their viscoelastic properties measured by shear rheology, the DLP-printed hydrogels proposed soft-tissue repair. Interestingly, swelling ratio shape printed found be preserved when immersed in physiological environment. While demonstrated impressive X- Y-resolutions (85 µm), they limited producing hollow objects Z-direction. To address this limitation, 3D printing complex through two-photon (TPP) investigated time, using second composed 4 (DM = 50%). cavities 30 µm successfully resolution 10 µm, paving way design controlled precise structures, engineering.
