Photocrosslinkable graphene-enhanced biomaterial inks for improved printability and structural fidelity

Key Points

• The aim is to develop graphene-enhanced biomaterial inks that improve printability and structural fidelity in 3D printing applications.
• Utilized methacrylated gellan gum (GGMA) as a base for hydrogel inks.
• Conducted extrusion-based 3D printing tests to assess printability and structural stability.
• Evaluated rheological properties to ensure proper flow and curing during printing.
• The graphene-enhanced inks showed significant improvements in printability compared to traditional inks (specific metrics not provided).
• Enhanced structural fidelity was observed with a higher degree of network stability post-printing (specific metrics not provided).
• Significant correlation between rheological properties and printing performance was established, emphasizing material customization.
