Polymeric materials are widely used in medical engineering, and with the dynamic development of additive manufacturing (AM) technology, increasing attention is being paid to research on the mechanical strength of composite polymer structures. At the same time, the impact of sterilization on, for example, surgical templates and the influence of the sterilization process on the geometry of these parts have not been sufficiently studied. In this work, the effect of steam sterilization on samples made of polymer materials for medical applications was presented. This research was carried out on samples with normative geometry made of polyetheretherketone (PEEK) polymers produced using the Material Extrusion (MEX) AM process and acrylic formulation (MED610) produced by Jetting Modeling Technology (JMT). These materials provide biocompatibility, which makes them suitable for potential medical applications. Steam sterilization was performed in an autoclave at temperatures of 121 °C and 134 °C. The three-point bending strength properties were determined according to ISO 178 standards. An INSTRON 5967 strength testing machine was used for those tests. Surface roughness analysis (according to ISO 21920) was performed and presented in 2D and 3D surface views using the Mountains Map Software (version 6.0).
聚合物材料在医学工程中广泛应用，随着增材制造（AM）技术的蓬勃发展，复合聚合物结构的机械强度研究日益受到关注。与此同时，灭菌对手术模板等的影响以及灭菌过程对这些部件几何形状的影响尚未得到充分研究。在这项工作中，展示了蒸汽灭菌对医疗应用聚合物材料制成的样品的影响。本研究针对采用材料挤出（MEX）增材制造工艺生产的聚醚醚酮（PEEK）聚合物以及喷射建模技术（JMT）生产的丙烯酸配方（MED610）制成的具有标准几何形状的样品进行。这些材料具有生物相容性，使其适用于潜在的医疗应用。蒸汽灭菌在高压灭菌器中于121℃和134℃的温度下进行。根据ISO 178标准测定三点弯曲强度性能。使用INSTRON 5967强度测试机进行这些测试。使用 Mountains Map软件（版本6.0）进行表面粗糙度分析（根据ISO 21920），并以二维和三维表面视图呈现。
