MethodMethodological development and computational simulation

ProcedureA visual programming environment was used to create a data flow for part optimization. This involved using parametric design tools to structurally optimize the overall geometry, infill, and shell of parts. The infill patterns were generated algorithmically and varied non-uniformly to respond to local load requirements, rather than using pre-defined patterns.

Design Principles

"Performance-driven design through algorithmic optimization."

This approach moves beyond standard design practices by using algorithms to define form based on performance requirements, rather than starting with a predefined aesthetic. This can lead to more efficient and lighter components, reducing production costs and environmental impact.

What This Means for Your Design

You can use computer programs to design 3D printed parts that are lighter and stronger by telling the computer how the part will be used and what forces it will experience. The computer then figures out the best shape and internal structure, rather than you having to guess.
