Additive Manufacturing is a promising key technology for innovative products and efficient production processes. Additive Manufacturing enables the production of product shapes with complex geometry and innovative features as well as individualization and personalization in production. A key approach for Additive Manufacturing is the digital workflow which starts with a digital representation of the product shape designed through using an appropriate CAD-system and which provides numerical control data for controlling the additive manufacturing process. Within this contribution the digital workflow is presented through its major steps indicating the state of the art as well as research approaches for future improvement. Furthermore it is explained how innovation is been created within the digital workflow.
