Compared to traditional reduced material manufacturing technology, additive manufacturing technology has multiple advantages: high freedom in design, cost saving in small batch production, high material utilization rate, good production predictability, and shortened production process. Therefore, additive manufacturing technology has been increasingly valued and widely applied in recent decades. 

The use of additive manufacturing technology to prepare metal materials and components is currently a very popular research field. Metals such as steel, Cu, Al, Mg, and NiTi can be prepared through additive manufacturing technology. In order to prepare more comprehensive materials, researchers have conducted extensive research work.

Due to its short development time and incomplete additive manufacturing technology, the microstructure and mechanical properties of materials prepared using additive manufacturing technology are often worse than those prepared using traditional reduction manufacturing methods. Therefore, there are many shortcomings that need to be improved.

In order to continuously improve additive manufacturing technology, Materials Science in Additive Manufacturing has established a special issue and invites researchers to actively contribute.
