High Value Manufacturing

Additive Manufacturing

- No chips - Freeforms - Complex shapes - Internal shapes - Customization - Materials range - Graded materials

- Lightweight - Internal geometries - Multi-functional - Porosities

High Value Manufacturing

Good opportunity to change the

World by

Accelerate innovation Redesign

New concepts

High Value Manufacturing Why reduce weight ? - less buiding time

- less waste during production (no chips) - less energy during production - less energy during transport - less energy during component using - reduce cost - Carbon footprint ? (Interreg FRED)

Vanguardist sectors

- Aeronautic - Spatial - Automotive - …
