## 1 Introduction
Through performance testing simulation on thin and hollow parts, the study demonstrated that thermal stress increased with layer height and decreased after substrate removal, and the maximum uniaxial plane stress transitioned from tensile to compressive stress from the edge to the center, ultimately reaching an equilibrium state. During the printing of thin plates, macroscopic thermal deformation was concentrated at the same plane corner, with the greatest deformation occurring in the \(z\)-axis direction. Laser power and scanning speed are important process parameters that affect the molding quality and mechanical properties of parts. [PERSON] et al. [22] found that with the increase in scanning speed, the number of pore defects and porosity increased in the SLM-formed Ti-6 Al-4V alloy. The alloy structure exhibited acicular \(\alpha^{\prime}\) martensite, and the scanning speed had little influence on the microstructure morphology, but the effect of scanning power was not considered. [PERSON] et al. [23] conducted numerical simulations on the formation process of aircraft hinge structures at different scanning speeds using three laser powers and found that residual stress and deformation showed a trend of improvement followed by deterioration with increasing laser power. [PERSON] et al. [24] utilized SLM technology to print a bridge-shaped structure and evaluated residual stress qualitatively using the bridge curvature method. They compared the effects of different laser scanning patterns, parameter settings, and process parameters on residual stress and found that the part exhibited overall upward warping after separating from the substrate. [PERSON] et al. [25] discovered that using zone island scanning during the printing of TC4 material effectively reduced the maximum warping. [PERSON] et al. [26] created a simulation model of the temperature field for a single-layer multi-pass method at various scanning speeds while accounting for the microstructure morphology. They combined experiments to analyze the generation of defects, microstructure, and mechanical properties, including anisotropy. The results showed that with the increase of laser scanning speed, the wettability of the liquid phase decreased, the internal porosity increased, and with the increase of scanning speed, the depth and width of the melt pool gradually decreased, making it difficult to form a good metallurgical bond. [PERSON] et al. [27] found that when SLM printing, a volumetric energy density that is too low will cause cracks and form irregular shape defects, and when it is too large, a large amount of powder will be attached to the surface, and even serious warpage deformation will occur, accompanied by large-sized round holes. The conventional method for inspecting the quality of SLM forming is experimental, involving mechanical analysis of simple printed specimens to assess whether the designed process parameters yield satisfactory model quality. In this study, by simulating the manufacturing process of a turbine structure for aerospace engine turbines, the optimal solution for process parameters is analyzed without the need for physical printing. This approach addresses the issue of poor interpretability between simple structural samples and complex components, which is often encountered in experimental methods. Through analysis of process parameters, this study investigates the energy utilization efficiency during the manufacturing process of turbine pump structures using SLM. This research has the potential to effectively reduce production costs for complex components based on the SLM method.
