Fused Deposition Modelling (FDM) is a widely used printing process in low-cost additive manufacturing technology. FDM is a well-known method of 3D printing on plastics, however, now it can be used for printing on metallic materials as well. For the past few decades, the polymer material is one of the most preferred choices of material studied for 3D printing especially to produce implants. In this study, nano-Hydroxyaptite incorporated with Polycaprolactone and Polylactic Acid (PCL/PLA/n-HA) are designed to inform of a scaffold with different porosity and compression performance were tested using ANSYS simulation. Combining n-HA into a PCL / PLA composite offers alternative options for the FDM raw material filament formula for a biomedical scaffold. For scaffold design, the dimensions are 10 mm x 10 mm x 10 mm in size. The porosity of the scaffold is set at 35.3%, 47.06%, and 70.59%, which are necessary to study the porosity value of the scaffold that performs under the compression mode. Next, the scaffold was tested via simulation by using Finite Element Analysis in SolidWorks 2020. The mechanical properties analyzed through compression in SolidWorks 2020 is Von Mises Stress, Equivalent Strain, and Resultant Force and the compression value are set at 20N, 30N, 40N, 50N, and 60N respectively. Throughout the analysis, PNC 2 with a porosity of 47.06% resulted in the lowest minimum stress and intermediate value in maximum stress in Von Mises. An equivalent strain through this analysis showed that PNC 2 with a porosity of 47.06% has the ideal characteristics where it has the highest minimum stress and the intermediate maximum strain. In resultant displacement, PNC 3 with 70.59% porosity resulted in the highest value in resultant displacement and it is not an ideal characteristic for a scaffold design in bone regeneration. Overall, PNC 2 with a porosity of 47.06% has shown the most ideal characteristics in Von Mises, Equivalent Strain, and Resultant Displacement and is ideal for scaffold fabrication using PCL/PLA/n-HA composite through 3D printing.
