Analyzing 3D printed structures Goals
Question: What’s makes the analyses of 3d printed structures complicated? Answer:
- The printing process settings effect the material behavior significantly
– Anisotropic structural and thermal material behavior – Micro scale geometry influences the macro structure (multi scale)
- Significant residual stresses and unwanted deformation can occur during the printing
process
