The article presents the research results on the influence of variable shock conditions, such as temperature and water, thus reflecting shock atmospheric conditions during freezing and thawing, on the properties of samples produced using 3D printing technology from commonly used materials such as ABS, HIPS, PLA, and ASA. Understanding how different environmental conditions affect the quality, reliability, and durability of 3D prints can help to optimize the printing process and provide valuable information about their application possibilities. Tests related to the strength of the materials, such as static tensile testing, Charpy impact testing, and evaluation of structures, were carried out using a scanning electron microscope (SEM). Changes in chemical properties were measured by performing tests such as FTIR and TGA. Variations in chemical properties were measured by performing tests such as FTIR and TGA. One shock cycle lasting 7 days was sufficient to alter the properties of 3D prints, with the extent of changes depending on the material, as summarized in the test results.

本文介绍了诸如温度和水分等可变冲击条件（反映冷冻和解冻过程中的冲击大气条件）对使用3D打印技术由常用材料（如ABS、HIPS、PLA和ASA）制成的样品性能的影响的研究结果。了解不同环境条件如何影响3D打印件的质量、可靠性和耐久性有助于优化打印过程，并提供有关其应用可能性的有价值信息。使用扫描电子显微镜（SEM）进行了与材料强度相关的测试，如静态拉伸测试、夏比冲击测试和结构评估。通过进行FTIR和TGA等测试来测量化学性质的变化。如测试结果所总结，持续7天的一个冲击循环足以改变3D打印件的性能，变化程度取决于材料。
