"The study of fabricating topologically optimized parts is presented hereafter. The mapping of topology optimization results for Standard Tessellation Language (STL) writing would enable the solid freeform fabrication of lightweight mechanisms. Aerospace leaders such as NASA, Boeing, Airbus, European Aeronautic Defense And Space Company (EADS), and GE Aero invest in topology optimization research for the production of lightweight materials. Certain concepts such as microstructural homogenization, discretization, and mapping are reviewed and presented in the context of topology optimization. Future biomedical applications of solid freeform fabrication such as organ printing stand to save millions of lives through the robust development of optimized technology. The ability of topologically optimized parts to perform mechanically is presented using FEA and compression testing. A comprehensive user input/output topology optimization software results from the investigation. Functions such as accepting any user design volume, loading, constraining, performing optimization, scaling, and writing an STL file are coalesced into one program named optstl. The pre-existing publicly available software packages have been primarily for graphical use, such as 3D plots, and thus cannot be directly interfaced with solid freeform fabrication technology. The reduction of multiple software interfaces into a simplified MATLAB program and the ability to write STL files of topologically optimized models provides scientists and engineers this interfacing ability. The results of this study are evaluated using finite element analysis (FEA), compression testing, and statistical testing"--Abstract, page iii.
