Why we look at the Additive Manufacturing?

Why design / redesign components?
To make sure that an added value is designed into the part
• Extreme performance increase
• Lightweight parts
• Stronger parts
• Part cost reduction

Traditional CAD systems rely on Boolean operations

What is Topology Optimization?
Topology optimization is a mathematical approach that optimizes material
layout within a given design space under given operating conditions.
