“…Interestingly, these two rules can be interpreted as related to production rather than design. Whilst the impact of build orientation for AM components is widely recognised (Cooke et al 2011;Urbanic and Hedrick 2015) it has only recently been recognised as an issue to consider in the design process instead of a decision to be made in production (Leutenecker-Twelsiek, Klahn, and Meboldt 2016). This highlights that in AM, design and production decisions are closely interrelated, and that the designer must also act as 'production engineer'.…”

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.

“…Design for AM (DfAM) is field of research with many contributions in recent years [36][37][38][39]. Methods and guidelines have been proposed for different purposes, for example methods to inspire novel designs [39][40][41], guidelines for manufacturability with specific processes [42][43][44] or to generally guide in assessing suitable designs [45]. Kumke et al [36] categorize DfAM research into DfAM in the strict sense (concerning the design of the component) and DfAM in the broad sense (concerning part and process selection and manufacturability).…”

Additive Manufacturing (AM) provides several benefits for aerospace companies in terms of efficient and innovative product development. However, due to the general lack of AM process understanding, engineers face many uncertainties related to product qualification during the design of AM components. The aim of this paper is to further the understanding of how to cope with the need to develop process understanding, while at the same time designing products that can be qualified. A qualitative action research study has been performed, using the development of an AM rocket engine turbine demonstrator as a case study. The results show that the qualification approach should be developed for the specific application, dependent on the AM knowledge within the organization. AM knowledge is not only linked to the AM process but to the complete AM process chain. Therefore, it is necessary to consider the manufacturing chain during design and to develop necessary knowledge concurrently with the product in order to define suitable requirements. The paper proposes a Design for Qualification framework, supported by six design tactics. The framework encourages proactive consideration for qualification and the capabilities of the AM process chain, as well as the continuous development of AM knowledge during product development.

“…More recently, the design principle early determination of the part orientation, which states that the orientation should be determined before the final design of the part begins, was proposed in Ref. [52]. A new process to determine the build orientation based on dividing the concept design of the part into several design elements, and analyse them separately to determine their best orientation and the global orientation of the part, was envisaged in Ref.…”

Although several research works in the literature have focused on studying the capabilities of additive manufacturing (AM) systems, few works have addressed the development of Design for Additive Manufacturing (DfAM) knowledge, tools, rules, and methodologies, which has limited the penetration and impact of AM in industry. In this paper a comprehensive review of design and manufacturing strategies for Fused Deposition Modelling (FDM) is presented. Consequently, several DfAM strategies are proposed and analysed based on existing research works and the operation principles, materials, capabilities and limitations of the FDM process. These strategies have been divided into four main groups: geometry, quality, materials and sustainability. The implementation and practicality of the proposed DfAM is illustrated by three case studies. The new proposed DfAM strategies are intended to assist designers and manufacturers when making decisions to satisfy functional needs, while ensuring manufacturability in FDM systems. Moreover, many of these strategies can be applied or extended to other AM processes besides FDM.
