Dear Colleagues,

Recently, Powder Metallurgy and Additive Manufacturing processes including 3D and 4D printing have gained increasing attention and attracted interest due to their potential to produce novel materials with unique tailor-made properties and with improved performance than the conventional materials in a sustainable and energy-efficient manner. Moreover, these processes offer the unique advantages of tailoring both the microstructure and properties apart from fabricating the parts with improved functionalities. As the process is enriched with all the allied instruments (including materials, materials production, processing, post-processing, standardization, etc.) getting advanced or standardized, there needs a definite platform to discuss the recent trends in these processes right from feedstock powder to its applications. Accordingly, this Special Issue will cover all aspects including synthesis feedstock powder (alloy development, powder production, and processing, powder characterization, powder properties, etc.), process (process simulation, process optimization, process parameter selection, process improvisation, etc.), post-processing (heat treatment, blasting, surfacing, microstructure optimization, etc.), materials characterization, materials testing, standardization, numerical modeling, and simulation, until its final applications. The main objective, thus, will be to bring the latest results in the areas of powder metallurgy, 3D printing, and 4D printing to the research community worldwide.

Scientific contributions are invited from scientists, researchers, engineers, and industry to disseminate recent inventions and developments in the field of AM. The potential topics include but are not limited to:

• Alloy systems and alloy development
• Powder production;
• Powder properties;
• Consolidation processes;
• Next-generation 3D/4D printing
• Innovation in processing strategies
• Innovation and advancement in powder production
• Microstructure–property correlation
• Post-processing and its strategies
• Defect and failure analysis
• Simulation and modeling
• Standardization and benchmarking
• Industrialization of the process
• Applications

This Special Issue looks forward to receiving submissions in any form, including review articles, regular research articles, and short communications. Both experimental and theoretical studies are of interest.
