“…external stress) the solution principle should be dimensionally stable and reliable in its functionality ( 9). François et al (2018) explicitly refer to the post-processing of functional surfaces and recommend that they should be oriented in the same direction whenever possible. Since post-processing functional surfaces removes material, an excess of these surfaces is necessary to counteract the material removal and the resulting tolerance deviations (10).…”

Additively manufactured final products and components are not always tailored to the additive manufacturing (AM) process, but they need to be in order to exploit the many advantages and potentials that AM provides. Therefore, an appropriate AM design should be targeted, which reduces the necessary iterations in the developing process of AM products. Although there is a large number of existing literature on the Design for Additive Manufacturing (DfAM), designers usually lack criteria in order to assess AM-conformity in conceptual design. In this paper, we provide a basis for the assessment of solution principles regarding their conformity for additive manufacturing.First, existing literature on DfAM and AM products is reviewed comprehensively to derive criteria for the AM-conformity of solution principles. Subsequently, the correlations between these criteria are identified including the interdependencies to be considered when assessing AM-conformity. A basis for assessment is created, which offers designers early support in the development of AM-conformal designs.

“…Since AM is said to enhance the probability of creating innovations (Wai, 2001), there are often great incentives for both companies and individuals to approach AM in their design practices. However, even though AM seems to have its own motivational power, design creativity is not considered to be managed while handling AM in design (Francois et al, 2019). There is therefore a need to retain encouragement and motivational perspectives in creativity management in order to support designers in utilizing their creative potential.…”

While many argue that Additive Manufacturing (AM) opens up new possibilities in design due to its higher degree of design freedom, it is also suggested that it can increase creativity in product design. It has been further proposed that creative outcomes are limited by the imagination of the designer: designers are often asked to take full advantage of the new design potentials given by AM, yet without having the supports that are needed to increase their creativity. Current literature focuses neither on supporting creative perspectives in Design for AM (DfAM) nor on how to manage the higher degree of design freedom that can be present. As a consequence of this noticeable gap in the literature, this paper continue to explore what areas that need to be considered in creativity management, to fully support designers in utilising their creative abilities in relation to AM in design. The paper proceeds through a literature study on creativity in DfAM and presents a case study with experienced designers who are just starting to work with AM in their design practices. This paper contributes to the field with the notion of a creativity layer laid upon DfAM, visualized by three characteristics of creativity (expertise, creative thinking skills and motivation) drawn from previous research. This results in three concrete propositions of areas that need to be considered in future research on how to include a creativity management perspective in DfAM.

“…Often, the full potential of AM technologies is not leveraged, and direct application of AM for products with existing traditional manufacturing solutions is not economically viable [2]. Thus, industries must focus on designing and developing products that are suited for AM rather than using the technology as a direct replacement of traditional manufacturing processes [3]. A decision support system (DSS) can aid in finding potential candidate products for AM through systematic evaluation of alternatives.…”

“…However, the priorities of most DSS solutions revolve around productivity and economics and seldom integrate design for manufacturing and assembly assessments. Recently, research effort has been directed towards building integrated DSS solutions capable of evaluating the technical and economic aspects of production [3,4]. Nevertheless, such solutions are still in their infancy and require a significant amount of human interaction.…”

Additive manufacturing has been presented as a novel and competitive method to achieve unprecedented part shapes and material complexities. Though this holds true in niche markets, the economic viability of additive manufacturing for large-scale industrial production is still in question. Companies often struggle to justify their investment in additive manufacturing due to challenges in the integration of such technologies into mainstream production. First, most additive technologies exhibit a relatively low production rate when compared with traditional production processes. Second, there is a lack of robust design for additive manufacturing methods and tools that enable the leveraging of the attendant unique capabilities, including the ability to form organic part geometries and automated part consolidations. Third, there is a dearth of systematic part screening methods to evaluate manufacturability in additive manufacturing. To tackle the challenge of manufacturability evaluation, the present work proposes a novel approach derived from latent semantic analysis and dimensional analysis to evaluate parts and their production for a variety of selected metrics. The selected metrics serve as descriptors of design features and manufacturing functions, which are developed using functional modeling and dimensional analysis theory. Singular-value decomposition and Euclidean distance measurement techniques are used to determine the relative manufacturability for a set of parts for a specified manufacturing process technology. The utility of the method is demonstrated for laser powder bed fusion technology. While demonstrated for additive manufacturing here, the developed approach can be expanded for any given set of manufacturing processes. Expansion of this systemic manufacturability analysis method can support part design decision-making, process selection, and design and manufacturing optimization.
