Abstract

This study is an attempt to analyse the 3D printing of the female femur model of the central India region and provides ample suggestions for bone implant research. This article discusses the design development and experimental validation of finite element analysis (FEA) results with the 3D-printed bone model. Using CT scan data, the FE analysis is executed on a real femur bone of a 25-year-old female of 52 kg weight with heterogeneous material characteristics and physiological loading conditions. The femur bone model is fabricated using a cost-effective 3D printer, fused deposition modelling (FDM), with a filament spool of polylactic acid (PLA). Compression tests were conducted on the fabricated PLA femur-bone model derived from a CT scan, providing insights into its mechanical behaviour under a specific load of 510 N. The total deformation during the FE analysis and compression test of the 3D printed model was 1.339 mm and 1.558 mm, respectively. The results show a strong relationship between porosity, mechanical strength, and chemical and biological stability, which is crucial for patient-specific modelling (PSM), designing medical implants and understanding implant and injury mechanisms.

Keywords: Femur, finite element analysis, 3D printing, FDM, patient-specific modelling, implants design.
