COMPARING 3D PRINTING TECHNIQUES (SLA VS. FDM) FOR THEIR USE IN RADIONUCLIDE METROLOGY

Abstract

This paper presents a comparative analysis, in which we evaluate the parameters of SLA and FDM printing technologies, for the production of radioactive standard sources in the SARPAGAN geometry, frequently encountered in radionuclide metrology. Aspects such as material compatibility, dimensional accuracy, radiation stability and the influence of 3D printing technology on the reliability of the final product will be addressed. Furthermore, the results obtained by gamma-ray spectrometry on a sample of99m Tc, using the standard SARPAGAN geometry, in comparison with the two 3D printed SARPAGAN geometries (SLA and FDM), were analyzed to evaluate how both the material and the technique printing of the geometry influences the results.
