| Abstract Scope |
Subtract-additive hybrid manufacturing systems have been developed to improve manufacturing time and cost for customized parts. However, CAD tools are limited to support design activities, such as modifying an original design for the hybrid manufacturing and detecting internal defects. In this research, we proposed an implicit CAD system and show applications to support design for additive manufacturing activities for subtract-additive manufacturing system. We considered two activities, model modification and defect detection. In the proposed CAD system, two function-fields are defined and utilized, which are signed distance and material function fields. The result shows the proposed algorithm effectively modified a CAD model to self-supported model, which can be fabricated with support structures. The proposed approach also estimates a distribution of defects as varying process parameters. |
