title Defects Defined by Form Making Method for Improving Generative Design System
source International Conference on Generative Art
summary Evolutionary-based Generative Design System (GDS) is generally designed for industrial designers during the early stage of conceptual design. Although “additive” Rapid Prototyping (RP) methods are commonly applied for the physical realization, grown Surfaces Object (SO) created from these GDS still has room to be considered to a combined workable volume,especially for the more complex design. The inarticulate processes from GDS to Generative Production System (GPS) are linking up with different aspects and contexts as well as the conventional Computer-Aided Design (CAD)/RP integration, which has been conducted for along time. There are design constraints existing between 3D SO in industry design representation and feasible 3D production solution. Perception to object designing with knowledge is limited at SO forming by incomplete interpretations. Meanwhile, it is difficult to discern the problemsof incomplete object generation as hidden illegal design occurred from time to time because of the design constraints, despite the completion of the design representation. It has led to some of the invalidity of surface feature at the end. The reconstruction of the RP process ofthe SO pre-processing procedure can help to clarify these defects with thickness requirement in generative production. The aim of this paper is to verify an effective generative design strategy as a possibility ofimplementing method(s) or tool. They will be built within a surface-oriented GDS by mapping a valid object directly accepted by any RP system without any influence on generative object creating. Through the involvement of Form Making processes of RP from selected instants with their solid phenomena, evidences are used for defending this viewpoint.Throughout the process, generative design method and CAD method have been utilized for the creation of virtual form. The 3D printer and Fused Deposition Modeling (FDM) technology with “trial and error” method were employed in the RP processes.
