Topology Optimization for Additive Manufacturing
This paper gives an overview of the issues and opportunities for the application of topology optimization methods for additive manufacturing (AM). The main analysis issues discussed are: how to achieve the maximum geometric resolution to allow the fine features easily manufacturable by AM to be represented in the optimization model; the manufacturing constraints to be considered, and the workfl...
متن کاملSelf-supporting Topology Optimization for Additive Manufacturing
The paper presents a topology optimization approach that designs an optimal structure, called a self-supporting structure, which is ready to be fabricated via additive manufacturing without the usage of additional support structures. Such supports in general have to be created during the fabricating process so that the primary object can be manufactured layer by layer without collapse, which is...
متن کاملSupport structure constrained topology optimization for additive manufacturing
Background: With recent advances in additive manufacturing (AM) and topology optimization (TO), there is a significant interest in integrating the two fields [1]. Although TO and AM have flourished independent of each other, there is significant interest today in integrating them for two primary reasons: (1) Designs stemming from TO are geometrically complex, and therefore hard to manufacture u...
متن کاملTopology optimization with manufacturing constraints: A unified projection-based approach
Despite being an effective and a general method to obtain optimal solutions, topology optimization generates solutions with complex geometries, which are neither cost-effective nor practical from a manufacturing (industrial) perspective. Manufacturing constraint techniques based on a unified projection-based approach are presented herein to properly restrict the range of solutions to the optimi...
متن کاملA survey of manufacturing oriented topology optimization methods
Topology optimization is developing rapidly in all kinds of directions; and increasingly more extensions are oriented towards manufacturability of the optimized designs. Therefore, this survey of manufacturing oriented topology optimization methods is intended to provide useful insight classification and expert comments for the community. First, the traditional manufacturing methods of machinin...
