By comparing the differences between high-entropy alloys and traditional alloys, this paper highlights the outstanding advantages of highentropy alloys in modern 3D printing, and introduces the characteristics, defects and corresponding solutions of different types of 3D printing technologies. DED uses a laser, electron beam, or arc to melt the powder or wire form during deposition. SLM is to melt metal powder on a powder bed and use high-energy lasers to print geometrically complex products. EBM uses electron beam to melt metal powder. In addition, the constituent elements, processing conditions and working temperature are also important factors in determining the mechanical properties of high-entropy alloys. By adding or reducing elements and conducting some treatment, the properties of high-entropy alloys such as tensile strength, compressive properties, fracture strength and plastic strain can be found changed.
