Abstract

Design for additive manufacturing (DfAM) methodology is proposed to develop products with optimal performance provided by the design freedom of additive manufacturing. The design space consists of several domains which include geometry design, topology design, process planning, and material selection. Meanwhile, decisions should be made at different levels, e.g., melt-pool level, layer level, and product level. To explore and exploit the design space, a multi-disciplinary and multi-scale decision-making problem needs to be formulated and cannot be solved with existing approaches. In this talk, we will introduce a data-driven approach to this problem and presents its implementation in two AM applications: tailoring of meta-structure in the design of a customized ankle brace, selection of process parameter for adaptive bead generation in the Wire Arc Additive manufacturing (WAAM) process.
