Integrated Design for Additive Manufacturing Based on Skin-Skeleton Approach

Abstract : Additive Manufacturing can produce three dimensional complex products based on the virtual CAD model. This new manufacturing method brings new possibilities in design and manufacturing cycle by its new parameters and Design For Manufacturing approach can be used to consider these issues. Therefore, an integrated methodology of Design for Manufacturing approach is proposed for additive manufacturing in this paper. This methodology investigates the characteristics related to Additive Manufacturing in design stage. For this purpose, Skin-Skeleton approach is used to model the procedure from the first step to final one. This skin-skeleton model consists of usage and manufacturing model which are used to present the customer requirement, product specification and design trend by usage model as well as manufacturing procedure and its constraints by manufacturing model. For this purpose, Topological optimization and Power Crust algorithm are utilized as tools to present optimized usage skin and skeleton. Also, manufacturing model is presented due to AM characteristics. Therefore, this model helps us to identify usage and manufacturing attributes to provide an interface model to define the product model by analysis of different parameter related to design and manufacturing and their relations comprehensively. Therefore, this model permits to consider manufacturing constraints and attributes as soon as possible in design stage to provide a better solution as a final product model for design and manufacturing concurrently as an integrated approach. In order to validate this approach, a bag hook that produced by Fused Deposition Modelling which is a well-known additive manufacturing technique is used.
