Abstract：
The paper describes the type of changes in the structure and mechanical properties of 3D printed shapes under the influence of mineral oil. The effects of a room (23 °C) and elevated temperature (70 °C) on 3D prints manufactured by the FDM method and stored in oil for 15, 30, and 60 days on the change of properties and structure were investigated. The samples were produced from ABS (poly(acrylonitrile-co-butadiene-co-styrene)), ASA (poly(acrylonitrile-co-styrene-co-acrylate), PLA (poly(lactic acid)), and HIPS (high-impact polystyrene). Tests related to the strength of the materials, such as the static tensile test and Charpy impact test, were carried out. The structure was evaluated using a scanning electron microscope, and changes in chemical structure were determined by conducting FTIR (Fourier transform infrared spectroscopy) and TGA (thermogravimetric analysis) tests. The analysis of the results provided important information about the impact of mineral oil on specific materials. This is critical for designing and manufacturing components that can withstand mineral oil exposure in real-world environments. The materials underwent varying changes. Strength increased for PLA by about 28%, remained unchanged for ABS and HIPS during exposure for 30 days, and decreased for ASA with extended exposure up to 14%.
摘要：
本文描述了在矿物油影响下3D打印形状的结构和机械性能的变化类型。研究了房间（23°C）和高温（70°C）对通过FDM方法制造并在油中储存15、30和60天的3D打印物的性能和结构变化的影响。样品由ABS(聚(丙烯腈-共-丁二烯-共-苯乙烯))生产,ASA(聚(丙烯腈-共-苯乙烯-共-丙烯酸酯),PLA（聚乳酸），和HIPS（高抗冲聚苯乙烯）。与材料强度相关的测试，如静态拉伸试验和夏比冲击试验，进行了。使用扫描电子显微镜评估结构，通过进行FTIR（傅立叶变换红外光谱）和TGA（热重分析）测试确定化学结构的变化。对结果的分析提供了有关矿物油对特定材料影响的重要信息。这对于设计和制造能够在现实环境中承受矿物油暴露的组件至关重要。材料经历了不同的变化。PLA的强度增加了约28%，在暴露30天期间，ABS和HIPS保持不变，并且在延长暴露量高达14%的ASA中下降。
