Additive Manufacturing (AM) technology is currently being promoted as the spark of a new industrial revolution. The integration of 3D-printing technologies is gaining momentum into numerous emerging markets, including the medical industry. Particularly, AM technology enables the fabrication of physical parts by using initial data from medical images, such as Digital Imaging Communications in Medicine (DICOM) images. These parts can be used as customized implants or medical models, which precisely represent the patient’s anatomy. The production of these models has the promising potential to affect the preoperative planning, education, and surgical simulation process, leading to various benefits regarding the surgical outcome. The aim of the current study is to investigate the integration of AM technology in the fabrication of patient customized medical model from scanned anatomical images, acquired from Computed Tomography (CT) or Magnetic Resonance Imaging (MRI). In specific, after conducting a thorough literature review, the basic scope of this study is to demonstrate the process of the T4 vertebra (thoracic spine) production, by presenting the design, the manufacture, and the evaluation stage. With regard to the first stage, it is crucial to indicate the most appropriate open-source software program for the conversion of DICOM files to Standard Triangle Language (STL) files. After acquiring and optimizing the required medical data to the desired file format, the anatomical model is printed via Fused Deposition Modeling (FDM). Finally, the 3D-printed model is scanned via 3D-scanner and saved in STL file format, in order to measure and evaluate the results, regarding the dimensional declinations between the printed and the scanned model.
