Advances in

Additive Manufacturing of Light Metals

There is a huge interest from different industries including aerospace, marine, medical, automotive, and energy for light metals developed through additive manufacturing (AM) for optimum performance. These alloys will be used in extreme conditions of severe mechanical loadings (impact and cyclic), corrosive environments, and other harsh situations (e.g. radiation). Thus, developing additive manufacturing process parameters to successfully print these alloys can enhance the adoption of AM in different sectors. All current methods of AM including but not limited to laser/electron beam powder beam fusion, blown powder, wire and arc-related techniques, binder jetting, friction stir processes are of particular interest. The symposium also focuses on light metals developed through novel AM techniques, which are beyond the current beam technologies. Advanced characterization contributions including in-situ melt pool monitoring, radiography, electron microscopy, and etc. are also welcomed. The symposium chair invites researchers to discuss rapid solidification phenomena present in AM (experimental and numerical) and investigate concepts such as hot tearing, grain refinement, alloy design, and interface engineering. The use of advanced modeling techniques to redefine process parameter development and design for additive manufacturing including machine learning, topology optimization, and artificial intelligence is of importance.


With this theme in mind the organizers of the Processing of Critical Materials Symposium are inviting papers in the following commodities:

  • Energy storage materials: Lithium / Vanadium / Nickel / Cobalt / Graphite
  • Alloy Elements: Scandium / Niobium
  • Electronics: Gallium / Germanium / Indium
  • Rare Earth Elements: Magnets, catalysts, phosphors, and other diverse areas


The organizers are specifically interested in the following subject areas:

  • Mineral Beneficiation – Process development and operations from ore and recycled material
  • Hydrometallurgy – Process development and operations from ore, concentrates, and recycled materials.
  • Overall Project Advancements
  • Challenges in Processing Plant Engineering
  • Separation of REEs – technology, feed specifications, chemical and physical specifications of products
  • Critical Materials and the Environment
  • Recycling (batteries, electronic waste, etc)
