The spiral construct, visualized in both side and top views (Figure , I), demonstrates the embedded printing modality's potential for producing vascular-like networks and complex hollow structures. Similar studies in literature have achieved comparable results using alginatebased hydrogels in embedded systems. However, the MFG hydrogel provides additional advantages, such as improved biocompatibility, better integration with sacrificial inks, and tunable degradation rates, which are critical for applications like tissue scaffolding and biofabrication of vascularized tissues.
