Abstract WE43, a magnesium alloy containing yttrium and neodymium as main alloying elements, has become a well-established bioresorbable implant material. Implants made of WE43 are often fabricated by powder extrusion and subsequent machining, but for more complex geometries laser powder bed fusion (LPBF) appears to be a promising alternative.
The global aim of the theme of magnesium alloy processing by the selective laser melting technology is to enable printing of replacements into the human body. By combining the advantages of WE43 magnesium alloy and additive manufacturing, it is

The currently used methods of Mg AM include selective laser melting (SLM), powder bed fusion (PBF), wire arc additive manufacturing (WAAM), paste extrusion deposition, friction stir additive manufacturing (FSAM), and jetting technologies [ 26 ]. Among the different AM processes, WAAM and SLM are recently used to produce Mg alloy.
Using additive manufacturing (AM), any complex geometry and near net shape of the components can be produced. Manufacturing Mg alloy satisfying compositional, microstructural, and design features as per biomedical design specification through AM process requires thorough understanding of the microstructure-property relationship.
