Abstract During the selective laser melting process, a high-energy laser beam acts on
the powder, a molten pool is rapidly generated and the characteristic parameters are
constantly changing. Among them, temperature is one of the important parameters
in the forming process. Due to the generation of splash particles, there will be defects
in the microstructure, which will seriously affect the formation quality of the prepared
parts. Therefore, it is necessary to study the relationships between the splash behavior,
molten pool characteristics and product quality. The finite element simulation of the
transient temperature field was performed by ANSYS software. Time-series images
