| Abstract Scope |
Additive manufacturing through 3D printing has become essential in regenerative medicine for fabricating living tissues and scaffolds that replicate native structures. This process depends on biomaterials with suitable biocompatibility and mechanical properties. Among the factors influencing scaffold performance, printing parameters are crucial, as the anisotropic nature of 3D-printed constructs makes mechanical behavior highly dependent on printing direction and internal architecture. This study evaluated the effect of different internal infill patterns, at constant density, on the mechanical properties of gelatin methacrylate (GelMA) scaffolds produced by 3D bioprinting. Rectangular scaffolds with four distinct infill geometries were printed and subjected to tensile testing. The results showed that infill type significantly influenced tensile performance, with some patterns reaching nearly twice the tensile strength of others. The orientation of infill lines altered stress distribution within the scaffold. These findings highlight the importance of infill design optimization to enhance GelMA scaffold performance for tissue engineering applications. |
