Additive manufacturing (AM), a layer based material addition technology to create three-dimensional objects directly from a 3D CAD model with little restrictions regarding the shape of the object. Today AM is already a proven technology for direct part production. The challenge is to identify suitable components of a product that will benefit from AM s capabilities. To support the identification of parts this paper presents indicators to parts where a re-design for additive manufacturing will create the most added value. Furthermore the benefits of additive manufacturing are subdivided into process advantages and design advantages. This distinction is fundamental, because it represents a great impact on the development process itself and the design strategy. The advantages, indicators and design strategies are explained and illustrated on two cases.
