Design and analysis of 3D-printed PLA scaffolds: Enhancing mechanical properties

• Complex and innovative designs can enhance the mechanical properties of scaffolds. • Novel scaffold design shows substantial improvement over available designs in simulations and experimental analyses. • The research offers an easily manufacturable product using readily available polymer materials 3D printing has enabled researchers to create scaffolds that possess high mechanical compatibility. So far, printed scaffold structures have primarily focused on simple designs, leading to a limited understanding of complex structures. This study aims to create scaffolds by easily sourced 3D printing system (FDM) and material, Polylactic Acid (PLA), to improve surface area, porosity, and reduce weight. The study presents two innovative scaffold designs, Hybrid Dome Face Centered Porous Structure (HDFCPS) and Reinforced Dome-Arch Porous Structure (RDAPS) inspired by…
