Main Methods:

• Utilizing Grasshopper, a visual programming application, to establish a continuous data flow for part optimization.
• Employing parametric design tools for structural optimization of geometry, infill, and shell structures.
• Developing optimization processes that generate shapes from basic geometries rather than initial designs.

Main Results:

• Achieved lightweight designs through structural optimization of general geometry, infill, and shell.
• Created non-uniform infill patterns with elements sized according to local load requirements.
• Demonstrated a design methodology where final shapes are emergent from the optimization process.

Conclusions:
