How does TPMS lattice structure design behave during Laser Powder Bed Fusion (LPBF)? In this simulation, AM PravaH analyzes the thermal and mechanical behavior, deformation, and residual stress of complex TPMS structures during additive manufacturing.
Triply Periodic Minimal Surfaces (TPMS) are advanced lattice structures with repeating geometries that can provide lightweighting, high surface-area-to-volume ratios, and excellent potential for applications such as biomedical implants, heat exchangers, and lightweight components.
However, manufacturing thin-walled TPMS lattice structures can be challenging because thermal cycling during metal 3D printing can cause deformation, warpage, residual stress, and potential delamination.
Using the AM PravaH thermo-mechanical simulation module, engineers can analyze the printability and mechanical response of TPMS structures manufactured using LPBF additive manufacturing.
This simulation demonstrates:
• TPMS lattice structure simulation
• LPBF process simulation
• Thermo-mechanical analysis
• Thermal deformation and distortion
• Residual stress prediction
• Von Mises stress analysis
• Warpage and printability analysis
• Metal additive manufacturing simulation
A flash-heating-based approach is used to represent the thermal loading from multiple printed layers. The resulting heating and cooling cycles generate expansion, contraction, and tensile/compressive stresses within the TPMS structure.
The resulting von Mises stress distribution helps identify regions that may be more susceptible to failure during the LPBF printing process.
