Abstract

The rapid advancement of three-dimensional (3D) printing technologies has significantly expanded their potential applications such as sensors and detector technology. In this study, the gamma-ray shielding performance of ulexite-doped composite resins fabricated via Digital Light Processing (DLP) 3D printing was experimentally investigated to evaluate radiation attenuation capacity. Composite resins containing different ulexite loadings (0, 1, 3, and 5 wt%) were exposed to gamma rays at energies of 356, 662, 1173, and 1333 keV to evaluate their attenuation characteristics. The physicochemical properties of the composite resins were characterized using scanning electron microscopy (SEM), X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR), and thermogravimetric (TG) analysis. Additionally, mechanical performance was assessed through compressive and tensile strength measurements. The results demonstrated that increasing the ulexite ratio enhanced the shielding capacity, as evidenced by increased linear attenuation coefficients (LAC) and corresponding decreases in half-value layer (HVL), tenth-value layer (TVL), and mean free path (MFP). For instance, at 356 keV the LAC value increased from 0.0360 cm⁻¹ for the pure resin to 0.0451 cm⁻¹ with 5 wt% ulexite. This improvement is attributed to the increased density and effective atomic number of the composite resins, which promote photon-matter interactions. DLP printing enabled a homogeneous distribution of ulexite within the resin matrix and allowed precise control over composite resin fabrication, further contributing to enhanced shielding performance. These findings suggest that ulexite-doped DLP-printed composite resins have potential as effective radiation shielding materials, particularly against low- and medium-energy radiation. For higher energies, improvements in material density and thickness may be required.

增材制造在辐射屏蔽设计中的应用：用DLP技术生产掺无钙石聚合物，结构和物理性能

三维（3D）打印技术的快速发展极大地扩展了其潜在的应用，如传感器和探测器技术。在这项研究中，实验研究了通过数字光处理（DLP） 3D打印制备的掺无钙石复合树脂的伽马射线屏蔽性能，以评估其辐射衰减能力。研究人员将含有不同重量（0、1、3和5 wt%）的复合树脂暴露于356,662,1173和1333 keV能量的伽马射线中，以评估其衰减特性。采用扫描电镜（SEM）、x射线衍射（XRD）、傅里叶变换红外光谱（FTIR）和热重（TG）分析表征了复合树脂的理化性质。此外，通过抗压和抗拉强度测量来评估机械性能。结果表明，增大无晶石比可增强屏蔽能力，线性衰减系数（LAC）增大，半值层（HVL）、十值层（TVL）和平均自由程（MFP）相应减小。例如，在356 keV时，纯树脂的LAC值从0.0360 cm−1增加到0.0451 cm−1。这种改进归因于复合树脂的密度和有效原子序数的增加，这促进了光子与物质的相互作用。DLP打印使无脱石在树脂基体内均匀分布，并可以精确控制复合树脂的制造，进一步提高了屏蔽性能。这些发现表明，掺脱石的dlp打印复合树脂有潜力成为有效的辐射屏蔽材料，特别是对低能和中能辐射的屏蔽。对于更高的能量，可能需要改进材料密度和厚度。

期刊介绍： Applied Radiation and Isotopes provides a high quality medium for the publication of substantial, original and scientific and technological papers on the development and peaceful application of nuclear, radiation and radionuclide techniques in chemistry, physics, biochemistry, biology, medicine, security, engineering and in the earth, planetary and environmental sciences, all including dosimetry. Nuclear techniques are defined in the broadest sense and both experimental and theoretical papers are welcome. They include the development and use of α- and β-particles, X-rays and γ-rays, neutrons and other nuclear particles and radiations from all sources, including radionuclides, synchrotron sources, cyclotrons and reactors and from the natural environment. The journal aims to publish papers with significance to an international audience, containing substantial novelty and scientific impact. The Editors reserve the rights to reject, with or without external review, papers that do not meet these criteria. Papers dealing with radiation processing, i.e., where radiation is used to bring about a biological, chemical or physical change in a material, should be directed to our sister journal Radiation Physics and Chemistry.
