Special Issue Information

Dear Colleagues,

Additive manufacturing (AM), particularly in the realm of metals, is revolutionizing the way components and materials are designed, fabricated, and utilized across various industries. This Special Issue focuses on the latest advancements in additive manufacturing techniques, processes, and materials specifically tailored for metal applications. We aim to explore innovative approaches that enhance the properties, performance, and scalability of metal components produced through AM. Topics of interest include, but are not limited to, the development of novel metal alloys for AM, process optimization for improved mechanical properties, post-processing techniques, and the integration of AM in high-performance and critical applications, such as aerospace, automotive, and biomedical engineering. This issue will also consider the challenges associated with the quality control, standardization, and sustainability of metal AM processes. By bringing together cutting-edge research and practical insights, this Special Issue seeks to advance the state of the art in metal additive manufacturing and its applications.

Additive manufacturing has revolutionized the production industry by enabling the fabrication of complex geometries. In recent years, significant advancements have been made in 3D printing using metal filament, particularly with materials such as 316L stainless steel. Known for its high strength, corrosion resistance, and ductility, 316L stainless steel is well suited for demanding applications in the medical, marine, and aerospace industries. However, secondary processes such as debinding and sintering can lead to changes in the dimensions and mechanical properties of the final product. This study investigates the effect of layer thickness on the mechanical properties of 316L stainless steel produced through additive manufacturing. Samples were produced with varying layer thicknesses (100, 200, 300, and 400 µm) and tested for tensile strength, hardness, and density. The results indicate that tensile strength increases with decreasing layer thickness. The highest tensile strength (432 MPa) and hardness (213 Hv) were observed at a layer thickness of 100 µm. Additionally, phase analyses and microstructural examinations were conducted. The primary phases identified in the samples were face-centered cubic (FCC) austenite and body-centered cubic (BCC) ferrite (δ). In this study, the manufacturing parameters with 316L filament have been optimized, and their impact on the mechanical properties has been examined. Full article
