Description
3D printing of high-performance polymers enables the production of functional components with complex geometries that cannot easily be obtained by conventional manufacturing methods. A concern is the possible degradation of the materials properties of the 3D printed polymers under the irradiation conditions in particle accelerators and detectors. In the present study we have characterised the mechanical properties of different high-performance SLA and FDM 3D printed polymers for potential use in superconducting magnets before and after gamma and 24 GeV proton irradiation up to 10 MGy Since in superconducting accelerator magnets irradiation occurs at low temperature in inert atmosphere, at the CERN IRRAD facility we have irradiated the 3D printed polymer samples immersed in liquid helium in a cryostat, and simultaneously identical samples have been irradiated by the same proton beam in ambient air, outside the cryostat. Based on the results obtained by Dynamic Mechanical Analysis (DMA) and static and dynamic mechanical tests of non-irradiated and irradiated materials we discuss the effect of irradiation temperature. The effect of irradiation on the mechanical anisotropy of FDM printed polymers is addressed too.
