5. Additive manufacturing for patient-specific medical use

Kontodina, Theodora / Tzetzis, Dimitrios / Davim, J. Paulo / Kyratsis, Panagiotis


Additive manufacturing (AM) technology is currently being promoted as the spark of a new industrial revolution. The integration of AM technologies is gaining momentum into numerous emerging markets, including the medical industry. Predominantly, AM enables the fabrication of physical parts by using initial data from medical images. Such physical models have the promising potential to affect the preoperative planning, education, and surgical simulation process, leading to various benefits regarding the surgical outcome. The focus of this chapter is to investigate the integration of AM technology in the fabrication of patientcustomized medical model from scanned anatomical images. Specifically, the basic scope is to demonstrate the process of physically reproducing the T4 vertebra (thoracic spine) from a human body and measuring the dimensional accuracy of the deduced model. Following conversion and optimization of Digital Imaging and Communication in Medicine (DICOM) files to Standard Triangle Language files, the anatomical model was produced via an AM procedure. The manufactured model was scanned via 3D laser scanner in order to digitally be able to compare it with the model used (derived from the DICOM files). The flow line procedure is described and the results are discussed in terms of assessment of the dimensional declinations between the AM produced and the scanned model
