“…At the same time, the grain distribution of variable reference forming was more uniform, which reduced the number and length of the grain boundaries, thus reducing the defects and strength differences of the material. The material elongation was influenced by grain size and uniformity [34,35]. When the layer energy density index was three, the laser energy density produced temperatures outside the optimal temperature range for TC4 plasticity, resulting in grain distribution changes and lower elongation than that of the other specimens.…”

This paper presents an in-depth study of the variable reference process to improve the organization and properties of selective laser melting TC4 specimens. A relationship equation between body energy density and stratification is proposed. This study aimed to look into how layer and volume energy density affect the surface, tensile characteristics, and microstructure of specimens. The test findings demonstrated that specimen densities rise as the power index falls, with the most excellent density reaching 99.42%. The number of secondary α’ phases declined as the energy density of the laminae slowed down. The tensile strength of these specimens reached 1190.84 MPa, and the yield strength came at 1103.87 MPa with the same interval of variable laser power. This offers a fresh avenue for research into SLM to enhance the specimens’ overall performance.
