Abstract

A proposed method based on a so-called meshless method is designed to simulate the structural behaviors of 3D medical parts. To do the simulation, the STL (Stereo-Lithography) geometry, which is the main geometry format used in 3D printing and medical models, is adopted to be the analysis model. Moreover, the geometry model of the objects in STL format becomes the only model needed for the simulation. To achieve this, some geometry-related treatments are required, so some checking processes are designed to handle the analysis model during the analysis. Hence, with the proposed meshless method based on STL geometry, the simulation can be carried out in a simple and straightforward way with less preparation effort for analysis models. A 3D simulation has been conducted to demonstrate the effectiveness and efficiency of this proposed method. Besides, the parts with highly complicated shapes can also be simulated without difficulty.
