摘要

要实现材料挤压三维打印技术，就必须对所选材料有透彻的了解。本研究对 Gel-Lay™ 长丝进行了全面分析，为今后研究该特征长丝的应用提供了宝贵的见解。Gel-Lay™ 长丝由聚乙烯醇（PVA）和热塑性弹性体（TPE）混合而成。该材料根据其形态、化学成分、热行为和动态机械性能进行了评估。表征过程揭示了 TPE 材料的类型和过渡温度，为改进印刷工艺提供了途径。此外，该研究还探索了使用三种不同方法从印刷部件中提取 PVA 的过程，以确定哪种方法能使印刷部件的质量与提取 PVA 后的质量之间产生最显著的差异。随着 PVA 的去除，部件变得多孔，这使得这种材料在不同应用领域大有可为。

Characterization of partially soluble filament for use in material extrusion 3D printing technology

The implementation of material extrusion 3D printing for technological purposes necessitates a thorough understanding of the chosen material. This study conducted a comprehensive analysis of Gel‐Lay™ filament, providing valuable insights for future research directed towards the application of the characterized filament. Gel‐Lay™ filament comprises a blend of polyvinyl alcohol (PVA) and a thermoplastic elastomer (TPE). The material underwent evaluation based on its morphology, chemical composition, thermal behavior, and dynamic‐mechanical properties. The characterization process yielded insights into the type of TPE material and transition temperatures, offering avenues for enhancing the printing process. Furthermore, the study explored the process of PVA extraction from printed parts using three different methodologies to determine the approach resulting in the most significant difference between the mass of the as‐printed part and the mass after PVA extraction. With PVA removal, the parts became porous which makes this material very promising for different applications.

期刊介绍： Polymers for Advanced Technologies is published in response to recent significant changes in the patterns of materials research and development. Worldwide attention has been focused on the critical importance of materials in the creation of new devices and systems. It is now recognized that materials are often the limiting factor in bringing a new technical concept to fruition and that polymers are often the materials of choice in these demanding applications. A significant portion of the polymer research ongoing in the world is directly or indirectly related to the solution of complex, interdisciplinary problems whose successful resolution is necessary for achievement of broad system objectives. Polymers for Advanced Technologies is focused to the interest of scientists and engineers from academia and industry who are participating in these new areas of polymer research and development. It is the intent of this journal to impact the polymer related advanced technologies to meet the challenge of the twenty-first century. Polymers for Advanced Technologies aims at encouraging innovation, invention, imagination and creativity by providing a broad interdisciplinary platform for the presentation of new research and development concepts, theories and results which reflect the changing image and pace of modern polymer science and technology. Polymers for Advanced Technologies aims at becoming the central organ of the new multi-disciplinary polymer oriented materials science of the highest scientific standards. It will publish original research papers on finished studies; communications limited to five typewritten pages plus three illustrations, containing experimental details; review articles of up to 40 pages; letters to the editor and book reviews. Review articles will normally be published by invitation. The Editor-in-Chief welcomes suggestions for reviews.
