The paper "Post-Production Finishing Processes Utilized in 3D Printing Technologies" by Antreas Kantaros, Theodore Ganetsos, Florian Ion Tiberiu Petrescu, Liviu Marian Ungureanu, and Iulian Sorin Munteanu explores the enhancement of post-processing techniques to improve the quality of additive manufacturing (AM) components. The study focuses on optimizing various post-processing methodologies to address issues such as surface roughness, dimensional accuracy, and material properties. It reviews and evaluates a range of post-processing methods, including thermal, chemical, and mechanical treatments, and their effects on different AM technologies like selective laser sintering (SLS), fused deposition modeling (FDM), and stereolithography (SLA). The paper highlights the importance of tailored post-processing approaches in mitigating inherent defects, optimizing surface finish, and enhancing mechanical properties. It proposes novel post-processing procedures to achieve superior quality while minimizing fabrication time and costs. Key post-processing techniques discussed include cleaning, surface finishing, heat treatment, support structure removal, surface coating, electropolishing, ultrasonic finishing, and hot isostatic pressing (HIP). Each technique is analyzed for its effectiveness, challenges, and applications. For example, cleaning methods like precision water jetting are shown to be highly efficient in removing residual powders and support structures, while surface finishing techniques such as vapor polishing significantly improve surface smoothness without compromising material integrity. Heat treatment, particularly annealing, enhances mechanical properties by refining the microstructure and reducing residual stresses. Support structure removal is crucial for maintaining the integrity of intricate features, and surface coatings like polymer and metal coatings can enhance wear resistance and conductivity, respectively. The paper also addresses the challenges and limitations of post-processing techniques, including the need for consistent results across different geometries and materials, labor-intensive processes, and high costs. Despite these challenges, the integration of these techniques into the AM workflow can significantly contribute to the progression of knowledge and practical implications for manufacturers and researchers aiming to improve the quality standards of AM processes.The paper "Post-Production Finishing Processes Utilized in 3D Printing Technologies" by Antreas Kantaros, Theodore Ganetsos, Florian Ion Tiberiu Petrescu, Liviu Marian Ungureanu, and Iulian Sorin Munteanu explores the enhancement of post-processing techniques to improve the quality of additive manufacturing (AM) components.
