Dosimetric assessment of the impact of low-cost materials used in stereolithography in high-dose-rate brachytherapy

摘要

3D printing has become a popular and widely available technique of rapid prototyping. The impact of used materials on the dose distribution has been studied for high energy sources. However, brachytherapy sources emit lower energy photons, and materials used in 3D printing may differ. This study was conducted to analyze the influence of common materials (polylactic acid – PLA and acrylonitrile butadiene styrene – ABS) used in stereolithography.
