The 35th Design for X Symposium (DFX 2024)
DfX offers young scientists from the field of product development a platform for presenting new ideas and approaches to their research. (Registration is now OPEN)
Knowledge Base Repository
In addition to research papers, the Design Society is developing several valuable resources for those interested in the study of design. These include a repository of PhD theses, a library of case studies and transcripts of design activities, and an archive of our newsletters. Please note that these resources are accessible exclusively to Design Society members.

Abstract:
Multi-material topology optimization (MMTO) offers lightweight design potential compared to single-material topology optimization (SMTO). For integrating restrictions of manufacturing processes into a MMTO ordered SIMP model, a mapping scheme is used to assign them only to the relevant material sections. By filtering and projection of the design variables, manufacturing constraints are implemented without considerable increase in optimization effort. Optimization results are compared by objective function values, convergence and effects of manufacturing constraints. The improved manufacturability of the optimization results can be achieved with only slight reduction in the objective function value, which is due to the restriction of the design space introduced by manufacturing constraints.
