The layered construction inherent to additive manufacturing (AM) processes introduces unique challenges related to part geometry. This demands a better integration of knowledge during design to avoid the large number of design iterations. This paper aims to establish a framework for effectively delivering AM-related knowledge throughout the design process, particularly for designers who are not AM experts.
Two preliminary experiments were conducted to identify the types of AM knowledge that need to be transmitted and in what format, as well as the best time to integrate this knowledge into the design process. Accordingly, a six-phase knowledge transmission framework was developed to run in parallel with the design stages in a design for AM (DfAM) approach. This framework was then validated through three additional experiments.
The proposed framework enables a more informed design process by providing non-expert designers with relevant AM information. Its effectiveness was validated through experiments involving students with no prior AM knowledge, demonstrating improved design outcomes and reduced need for iterative rework.
This work stands out by proposing a sequence for providing information that is compatible with existing design methods. It offers a versatile approach that directly connects theoretical design methods with practical guidance, helping designers make more informed and effective decisions when designing for AM.
