Abstract Scope |
Design for additive manufacturing (DfAM) approach is a design methodology to utilize benefits from adopting additive manufacturing technologies. In this approach, all design information related to geometries, materials, and manufacturing processes need to be efficiently integrated. However, existing computer-aided design (CAD) systems cannot support DfAM activities efficiently because all information should be represented only by geometric information. The goal of this paper is to propose a field-driven CAD system to support DfAM activities. To achieve the goal, we implement shape modeling technics based on implicit representation, and we propose a method for creating and utilizing shape-material-process function fields for DfAM activities. To validate the effectiveness of the proposed CAD system, three DfAM activities including local shape modification, cellular structure generation and AM process optimization are performed, and results show the proposed CAD system efficiently supports DfAM activities. |
