Abstract
The reverse engineering method has been beneficial for personalized implant designs in the medical field due to its flexible use feature that allows it to be applied in many areas. The method of anatomical features (MAF) is commonly used for fractures of the bone for the development of plate fixation. To improve the geometrical fitting between plate and bone, high-quality image data is the most important factor for computer aided design (CAD ) modelling. This study aims to use MAF for humerus bone plate design that would alternate the fracture region and decrease the stress-shielding effect depending on bending strength. For this purpose, the personalized plate implant (PPI) was designed according to MAF and fabricated using the multi jet fusion (MJF) technique, finally the four-point bending finite element analysis was applied and tested. The results indicated that the PPI structure has higher bending strength than the flat plate design and a much greater surface area.
