Design for AM (DfAM) and Design with AM (DwAM)
摘要
For most applications, the intended functionality or properties are determined by not only intrinsic material properties but also geometry designs. It is well known that during the product design process, it is important to incorporate sufficient consideration of factors related to the manufacturing. In general, these additional consideration factors impose certain restrictions to the designs. There exist extensive guidelines and theories for modifying and optimizing geometry designs of structures and materials, which is generally termed as design for manufacturing (DFM). In a more extended context, DFM also encompasses material selection, process design, and quality inspection as additional factors. In general, the goal of DFM practice aims to reduce the cost and manufacturing-induced defects of a product. Due to the significant impact of design in the overall cost and supply chain structure of a product, ideally DFM should be implemented as an integral concept throughout the design process. However, in practice, this is often difficult to realize due to various reasons such as the fragmented supply chain, management structure, cost restriction, and cultural barrier. Consequently, DFM is often more narrowly interpreted as geometry modification practice after the primary form of the design is generated, potentially limiting its effectiveness.
