Various post-treatment techniques are often used to enhance the performance of the product. The aim of these post-treatments is mainly to increase the cross-linking density. The use of ionising radiation can be an excellent alternative for this purpose. In this study, gamma radiation was chosen as the ionising radiation and its applicability as a post-treatment technique was investigated. The printed samples were post-treated with absorbed doses between 25 and 200 kGy. Irradiation has significantly changed the mechanical properties. The tensile modulus for the untreated sample (0 kGy) was 1.92 GPa and it increased to 2.76 GPa after irradiation with 200 kGy, while the tensile strength increased from 38.1 MPa to 64.6 MPa. The heat deflection temperature of the untreated specimen was 48 degrees C, which increased to 60 degrees C for the 200 kGy irradiated specimen. The irradiation also had an effect on the thermal properties: the glass transition temperature increased from 46.7 degrees C to 59.6 degrees C, which is an outstanding result when compared to other post-treatment techniques. The changes in properties were caused by an increase in cross-link density, as confirmed by swelling and Fourier transform infrared spectroscopic analyses. The results presented in this study prove that high-energy gamma irradiation is a novel and effective tool to customise the mechanical and thermal properties of material jetting printed photopolymer parts. Gamma irradiation has clear practical benefits in industries where it is already applied, like medical device manufacturing, pharmaceutical or food industry, where strict sterilisation requirements can often be fulfilled by it. true NATIONAL 2025 true true true false true false NONE 2026-02-16 false 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 6 6 Q1 false 10073528,10042366,10026850,10076732 false false false 2025-11-24T12:43:04.871+0000 HUN-REN-BME Kompozittechnológiai Kutatócsoport (BME / GPK / PT); MTA-BME Lendület Könnyűszerkezetes Polimer Komp...
