Self-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 کاملTopology 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 کاملTopology optimization of thermally actuated compliant mechanisms considering time-transient e(ect
Thermal transducers, which can be regarded as thermally actuated compliant mechanisms, have found a wide range of applications, due to easy accessibility of heat source, and due to their good controllability and reliability. During the past decade topology optimization techniques have been developed as e7cient tools to design distributed compliant mechanisms and accepted by engineers. In this r...
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...
