DEC31B - Importance of Fabrication Constraints in Topology Optimization

Using fabrication constraints with Topology Optimization enable you to simultaneously optimize designs for weight/performance and manufacturability while still in the early design stage. This presentation will discuss how to use fabrication constraints in topology optimization along with their typical applications. They help the engineer to obtain manufacturable designs while reducing the weight. The general fabrication controls include minimum/ maximum component dimensions, symmetries, cyclic symmetries etc. Extrusions can be applied for designing plastic parts or during the traditional milling process. For casting, the designer can require castability for given directions. This session will also cover how different types of fabrication constraints can also be combined together to achieve desirable designs.
