Residual stress and deformation analysis of lattice compressor impeller based on 3D printing simulation
Abstract
Based on the octagonal truss, a new lightweight lattice impeller (L-impeller) is designed. The 3D printing process of the design impeller is simulated by Finite Element Method (FEM). The machinability and simulation feasibility of the design impeller are verified by SLM280 Metal 3D printer. The printing process of L-impeller and solid impeller (S-impeller) under different power is analyzed and compared. The results show the maximum residual deformation of L-impeller is 20.19% smaller than that of S-impeller, and the maximum residual stress is 10.69% smaller than that of L-impeller, which means that the L-impeller will have better printing performance.

For Ti-6Al-4V lattice impellers, residual stress is lower than in solid ones, with a reduction in the maximum residual stress by 8.72%.
“In the case of Ti-6Al-4V applied to impellers, research indicates that residual deformation can be reduced by 20.19% compared to solid compressor impellers, and the residual stress in lattice impellers is lower than in solid ones, with a reduction in the maximum residual stress by 8.72% [71,72].”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
