Abstract

The application of three-dimensional (3D) printing in tissue engineering is rapidly expanding due to its ability to create highly complex structures, produce patient-specific designs, and offer quick and cost-effective on-demand manufacturing. Identifying the appropriate biodegradable scaffolds composed of suitable biomaterials with optimal mechanical strength, biocompatibility, uniform degradation, pore size, and porosity is crucial. This study aimed to design a scaffold model using 3ds Max software and fabricate it through a suitable 3D printing technique. Using CAD in 3ds Max, prototypes of both porous cubic and randomized cylindrical porous scaffolds were modeled. These designs were then printed using engineered resin and polylactic acid (PLA), employing Stereolithography (SLA) and Fused Deposition Modeling (FDM) 3D printing techniques, respectively.
