Design for Additive Manufacturing – Supporting the Substitution of Components in Series Products

The Additive Manufacturing technologies Selective Laser Sintering (SLS) and Selective Laser Melting (SLM) are capable to produce thermoplastic or metal parts, which are fit for end-user products. Both technologies create three-dimensional objects directly from a 3D CAD model with little restrictions regarding the shape of the object. This geometrical freedom in design can be utilized to largely improve the functionality of series products by substituting conventional parts with additive manufactured ones. Four criteria are presented here to identify components of a product for a re-design. A successful re-design has to meet the needs of the producer and his customers. The selection criteria and success factors for a re-design are demonstrated in four cases.
