Laser additive manufacturing processes. The LAM technology utilizes the laser beam as the energy source. The review focuses on the two types of LAM processes, particularly the laser powder bed fusion technology, which spreads powders on the substrate and directed energy deposition process with powder as feedstock materials.
3D printing or additive manufacturing is the construction of a three-dimensional object from a CAD model or a digital 3D model. It can be done in a variety of processes in which material is deposited, joined or solidified under computer control, with material being added together (such as plastics, liquids or powder grains being fused), typically layer by layer.

Additive Manufacturing (AM) appears to be the best candidate to manufacture random architected materials, as it offers significant freedom in the design of hollowed parts with complex geometry. However, when these structures are needed with thins walls and struts, AM processes may encounter difficulties in properly manufacturing these ...
Once discharge is complete, the cell components can be separated into different materials streams for further processing: steel can or laminated aluminium, separator, anode (graphite, copper ...
Today, a large number of different steels are being processed by Additive Manufacturing (AM) methods. The different matrix microstructure components and phases (austenite, ferrite, martensite) and the various precipitation phases (intermetallic precipitates, carbides) lend a huge variability in microstructure and properties to this class of alloys.

Selective laser melting (SLM) is one of many proprietary names for a metal additive manufacturing (AM) technology that uses a bed of powder with a source of heat to create metal parts. Also known as direct metal laser sintering ( DMLS ), the ASTM standard term is powder bed fusion ( PBF ).
Selective laser sintering (SLS) technology (invented in the mid-1980s by an American businessman) is a rapid manufacturing technique, which uses high-power CO 2 lasers to fuse particles together. The laser sinters powdered materials (metallic, ceramics, or polymer materials like white nylon powder).

Compounds containing rare earths have diverse applications in electrical and electronic components, lasers, glass, magnetic materials, and industrial processes. Despite their name, rare-earth elements are relatively plentiful in Earth' crust, with cerium being the 25th most abundant element at 68 parts per million, more abundant than copper.
Metal Additive Manufacturing (AM) processes, such as selective laser melting (SLM), enable the fabrication of arbitrary 3D-structures with unprecedented degrees of freedom. Research is rapidly progressing in this field, with promising results opening up a range of possible applications across both scientific and industrial sectors.

1. Introduction. Powder bed fusion (PBF) and directed energy deposition (DED) are typical metal additive manufacturing (AM) techniques. They build components in a layerwise manner, in which the 3D model is sliced into discretized 2D layers, and the energy source (e.g., laser, electron beam or arc) will scan each layer following the designed toolpath to form a 3D part .
