Abstract
Design for Additive Manufacturing maximizes the potential of Additive Manufacturing (AM) through design guidelines and tools. However, a methodological gap remains in integrating hollow structures to enable new functionalities, which is address in this contribution. The quantitative working space model (qWSM) is introduced as a tool to enable the examination of surface characteristics and their impact on channel functionalities in AM. The qWSM's dynamic representation of design embodiment supports updates for new design solutions, thus enhancing digital product development efficacy. Utilizing the qWSM, the relationship between surface roughness and state variables like pressure drop are explored. The objective is to refine the AM process and improve functionality through design guidelines.
