| Abstract [eng] |
In this study, new 3D printing materials using PLA and different concentrations (0.5%;1%;2%) of TiO2 have been produced. TiO2 concentration effect on the mechanical propertiesof the X-ray irradiated newly produced materials and their suitability for patient-specific applications has been investigated. Filaments have been produced using a 3D Devo filament extruder. Attenuation properties have been simulated using the XCOM database. Samples have been irradiated with 6 MeV energy photons with 2Gy and 70Gy. These values have been selected in order to see how the mechanical properties are affected after one treatment procedure and the whole treatment. Mechanical tests were performed using the ElectroPuls® E10000 Linear-Torsion machine. The results have shown that newly designed materials can solve current solutions issues and increase the needed mechanical parameters including the Yougn‘s module, Maximum load, and tensile stress. The results have shown that newly created filaments have the potential to change currently used materials for patient-specific applications. |
