Additive manufacturing (AM) technology is one of the most innovative production methods for metallic materials, in many industries, including aerospace and medical.
AM allows for the production of parts layer by layer, providing freedom of design, zero waste, reduced tool material requirements, and improved part properties. However, the materials produced by metal additive technologies, such as powder bed fusion, direct energy deposition, and binder jetting, are not yet as good as cast and wrought metallic alloys. This is due to, firstly, the limitations of laser-beam or electron-beam interaction and the susceptibility to cracking in laser-based production. Additionally, the number of developed powders up to now needs to keep pace with the development of AM technology. Therefore, designing and developing new powders by production improvements or by new alloy design is always demanding and taking great attention nowadays. In this context, advanced and AM-specific characterization of these powders is also needed.
In this special issue, studies with the potential of making attributions to this field will be covered.
Interested themes are:
Development of new alloy/composite/bimetallic powders suitable for AM technology (parts, lattice structures, multi-material, etc.)
Alloy design using computational materials design (CALPHAD techniques), optimization studies, and machine learning/artificial intelligence tools
Advances in powder production techniques such as atomization (gas, plasma, ultrasonic, etc.), mechanical alloying, chemical processing, and so on
Applications of advanced characterization techniques to evaluate the particle size, morphology, chemical composition, and phase analysis of the powders
Recycling/reuse/recovery of metal additive manufacturing powders
The use of statistical analysis, advanced characterization, and combined manufacturing processes
Keywords:
Additive Manufacturing, Powder Production Morphology, Gas Atomization
Important Note:
All contributions to this Research Topic must be within the scope of the section and journal to which they are submitted, as defined in their mission statements. Frontiers reserves the right to guide an out-of-scope manuscript to a more suitable section or journal at any stage of peer review.
