“…However, this principle is in contrast with much of the literature on DfAM, which emphasises the possibility of making complex shapes (Ahuja, Karg, and Schmidt 2014;Boyard et al 2014;Chryssolouris et al 2012;Hague, Campbell, and Dickens 2003;Saleh 2003, 2004;Hopkinson, Hague, and Dickens 2006). An interpretation could be that, even when complex geometries are possible, they might not always be an appropriate solution since complexity might interfere with other design requirements, for instance cleanability or maintenance.…”

Additive Manufacturing (AM) technologies are widely adopted in design practice for prototyping. However, the extent to which practitioners are knowledgeable and experienced in designing components for series production using AM remains poorly understood. This study presents the results of an online survey aimed at uncovering this emerging design activity, with additional evidence provided by semi-structured interviews with 18 designers. One hundred ten practising designers responded. The majority of the respondents remain sceptical about the potential for AM as a process for series production, citing cost and technical capabilities as key barriers. Only 23 reported experience in designing components for series production using AM, with the majority of these designing parts to be produced from plastic. The survey revealed that these designers have developed their own 'design rules' based primarily on personal experience. These rules, however, tended to focus on ensuring 'printability' and did not provide support for taking advantage of the unique capabilities of AM processes. The designers tended to treat AM processes as a uniform set of production processes, and so the design rules they used were generic and not directed to the capabilities of specific AM processes.

“…We deduced that the development of a creative approach to be integrated in DFAM methods could enhance the generation of fully creative concepts.

Without mentioning the specific paradigm of DFAM, it has been recognized that creative designers have different types of motivations (see the following section).…”

Emotional aspects and designers' motivations in Design For Additive Manufacturing are rarely studied. Still, as they can influence creative behaviors, it is worth of interest to draw some bases for a relation between designers' motivations and the field of Additive Manufacturing. This paper aims at identifying the motivations that push designers to deal with AM in their practice. We have highlighted that they experience some extrinsic motivations: technical improvements, economics and social environments pressures. We also notice that creative designers, apart from AM, usually experience some intrinsic motivations and, moreover, that it exists an ideal state to generate creative concepts: the Flow. To support creative designers in DFAM in reaching the Flow, we then identified 4 key levers through the potential of AM: the newness of AM processes, the needed skill of 3D modelling, the investigation of new shape grammars and finally the opportunity of embodying concepts into physical objects. To benefit from this potential, we assume that designers' intrinsic motivations should be supported: we identified three required conditions. The first one is the use of a proper vocabulary i.e the expression Additive Manufacturing instead of 3D Printing. The second one is the development of a design process which integrates a creative approach. The third condition is the use of AM objects as experience triggers during creative sessions to arise positive emotions.

“…To refine this classification, we conducted a study on 27 peerreviewed publications related to DFAM for decision making [8,9,13,[25][26][27][28][29][30][39][40][41][42][43][44][45][46][47][48][49][50][51][52][53][54][55][56]. Three different ways to assist designers were identified.…”

Additive manufacturing (AM) is emerging as an important manufacturing process and a key technology for enabling innovative product development. Design for additive manu-facturing (DFAM) is nowadays a major challenge to exploit properly the potential of AM in product innovation and product manufacturing. However, in recent years, several DFAM methods have been developed with various design purposes. In this paper, we first present a state-of-the-art overview of the existing DFAM methods, then we introduce a classification of DFAM methods based on intermediate representations (IRs) and prod-uct's systemic level, and we make a comparison focused on the prospects for product innovation. Furthermore, we present an assembly based DFAM method using AM knowl-edge during the idea generation process in order to develop innovative architectures. A case study demonstrates the relevance of such approach. The main contribution of this paper is an early DFAM method consisting of four stages as follows: choice and develop-ment of (1) concepts, (2) working principles, (3) working structures, and (4) synthesis and conversion of the data in design features. This method will help designers to improve their design features, by taking into account the constraints of AM in the early stages.
