Mini-symposium description 

The spectacular success and the fast development of topology optimization and additive manufacturing techniques are intrinsically related to each other. Topology optimization is a powerful and cost-effective computational tool to create innovative design concepts in engineering. The organic and geometrically complex design layouts obtained from topology optimization are generally too complex for conventional manufacturing techniques. The rapid development of additive manufacturing (AM) technologies is now enabling the cost-effective fabrication of these high-performance designs on a multitude of length scales with different classes of materials. Conversely, taking full advantage of the new AM capabilities calls for revisiting the classic component designs strongly related to traditional machining. Even though AM enables a larger form freedom in manufacturing, there are still specific manufacturing constraints. As the final structural and physical properties of the 3D printed components are strongly influenced by the design and the specifics of the AM process at hand, it is paramount to account for the manufacturing-induced effects and the manufacturing constraints in topology for AM products. Moreover, it is of great interest to control process conditions, along with the design layout to achieve properties that are beyond the reach of conventionally manufactured products. Consequently, future competitive AM designs involve both the layout of a structure as well as the local process conditions. This context motivates a very active research field focussing on developing computational techniques that can generate designs “ready-to-print” using additive manufacturing. 

 

This mini-symposium invites researchers to report their contributions in the context of computational techniques for “ready-to-print” designs. More specifically, the mini-symposium targets contributions that address: 

  • New developments in density-based or alternative approaches in topology and shape optimization in connection with 3D printed components. 

  • Adjoint sensitivity analysis in the context of optimization and additive manufacturing. 

  • Additive manufacturing constraints for topology and shape optimization. 

  • AM design rules and cost prediction models. 

  • Additive manufacturing process modelling and experimental validation. 

  • Simplified, computationally efficient and reduced-order AM process models. 

  • Prediction of distortion, residual stresses, microstructure and process failure of AM fabricated designs. 

  • Material modelling for additive manufacturing. 

  • Optimization and automated design of AM process parameters and support structures. 

  • Simultaneous optimization of design and process conditions. 

  • Design of structures with lattice and cellular structures. 

  • Links with CAD design tools to produce ready-to-print components. 

  • Industrial applications of topology for additive manufacturing.
