Introduction
Interpretation of lightweight design requirements for additive manufacturing structures
| Technical path | Key requirements | Application areas |
|---|---|---|
| Porous structure design | - Three-dimensional lattice, honeycomb structure, foam structure- Filling orientation and edge integrity | Aerospace, automobile manufacturing |
| Topology optimization design | - Mathematical modeling and finite element analysis- Model preprocessing and postprocessing | Industrial equipment, building structures |
| Process constraint optimization | - Limit size and overhang control- Closed cavity processing | Medical implants, electronic devices |
Implementation recommendations
To ensure the efficiency and reliability of lightweight design of additive manufacturing structures, it is recommended to:
- Use topology optimization software for mathematical modeling
- Reasonably select the filling orientation of porous structures to reduce overhang
- Evaluate stress concentration areas through finite element analysis
- Design domain division needs to be combined with actual working conditions
