“…Parts produced by AM have dimensional limitations due to the machines' build space capabilities (Oh, Zhou and Behdad, 2018a;Ramírez et al, 2019) consequently, parts may have to be designed as assemblies; known as part decomposition (Oh, Zhou and Behdad, 2018b). Post-production complexities are experienced due to errors from AM's digital and physical process chains that result in inconsistencies in the geometries of the final products (Polini et al, 2017), as a result, issues like tolerances should be addressed to control the geometrical deviations of the final product (Zhu et al, 2018).…”

“…Due to planar layer-AM, the rotation of the part in the build space around the axes of the machines’ coordinate system, that is, the part orientation with respect to the build plane (Leutenecker-Twelsiek et al , 2016), has a significant impact on the mechanical properties of the part and affects the final part quality and geometry (Zwier and Wits, 2016) which presents implications for design. Parts produced by AM have dimensional limitations due to the machines’ build space capabilities (Oh et al , 2018; Ramírez et al , 2019) consequently, parts may have to be designed as assemblies; known as part decomposition (PD) (Oh et al , 2018). Post-production complexities are experienced due to errors from AM’s digital and physical process chains that result in inconsistencies in the geometries of the final products (Moroni et al , 2017), as a result, issues like tolerances should be addressed to control the geometrical deviations of the final product (Zhu et al , 2018).…”

Purpose The purpose of this paper is to understand how Design for Additive manufacturing Knowledge has been developing and its significance to both academia and industry. Design/methodology/approach In this paper, the authors use a bibliometric approach to analyse publications from January 2010 to December 2020 to explore the subject areas, publication outlets, most active authors, geographical distribution of scholarly outputs, collaboration and co-citations at both institutional and geographical levels and outcomes from keywords analysis. Findings The findings reveal that most knowledge has been developed in DfAM methods, rules and guidelines. This may suggest that designers are trying to learn new ways of harnessing the freedom offered by AM. Furthermore, more knowledge is needed to understand how to tackle the inherent limitations of AM processes. Moreover, DfAM knowledge has thus far been developed mostly by authors in a small number of institutional and geographical clusters, potentially limiting diverse perspectives and synergies from international collaboration which are essential for global knowledge development, for improvement of the quality of DfAM research and for its wider dissemination. Originality/value A concise structure of DfAM knowledge areas upon which the bibliometric analysis was conducted has been developed. Furthermore, areas where research is concentrated and those that require further knowledge development are revealed.

Additive manufacturing (AM) brings new design potential compared with traditional manufacturing. Nevertheless, traditional manufacturing knowledge remains embedded in the minds of designers and is a real cognitive barrier to design in AM. Design for Additive Manufacturing (DfAM) provides tools, techniques, and guidelines to optimize design with the specifics of AM. These methods are usable at different moments of the design process. Only few DfAMs focus on the early stages of design, the ideation phase, which allows for the most innovation. The literature highlights the effectiveness of methodologies based on tangible tools, such as cards or objects, to generate creativity. The difficulty with such tools is to be inspirational as well as formative. Therefore, this article presents a method to help designers capture the design potential of AM to design creative solutions at the early stages of product design, named the Augmented Design with AM Methodology (ADAM 2 ). This methodology relies on the potential of AM, defined in 14 opportunities and a set of 14 inspirational objects, each representing an opportunity. Dedicated to creativity sessions, this methodology allows forcing the association between knowledge of a company's sector and the design potential of AM. To validate the effectiveness of the ADAM 2 methodology, we use it for an industrial application in a jewelry and watchmaking company. The results showed that ADAM 2 promote the generation of creative solutions and the exploitation of the design potential of AM during the early design stages.

“…The greater control of manufactured objects through data changes in the slicing code is in line with the progress of smart AM (Majeed et al , 2021; Ryan et al , 2021). The control of parameters under specific conditions is a great challenge and has opened up opportunities for new types of geometries (Klahn et al , 2016; Ramírez et al , 2019).…”

Purpose This paper aims to address the development and implementation of “AltPrint,” a slicing algorithm based on a new filling process planning from a variation in the deposited material geometry. AltPrint enables changes in the extruded material flow toward local variations in stiffness. The technical feasibility evaluation was conducted experimentally by fused filament fabrication (FFF) process of snap-fit subjected to a mechanical cyclical test. Design/methodology/approach The methodology is based on the estimation of the parameter E from the mathematical relationships among the variation of the material in the material flow, nozzle geometry and extrusion parameters. Calibration, validation and analysis of the printed specimens were divided into two moments, of which the first refers to the material responses (flexural and dynamic mechanical analysis) and the second involves the analysis of the printed components with localized flow properties (for estimating the response to cyclic loading). Finite element analysis assisted in the comparison of two snap-fit geometries, one traditional and one generated by AltPrint. Finally, three examples of compliant mechanisms were developed to demonstrate the potential of the algorithm in the generation of functional prototypes. Findings The contribution of AltPrint is the variable fill width integrated with the slicing software that varies the print parameters in different regions of the object. The alternative extrusion method based on material rate variation was conceived as an “open software” available in GitHub platform, hence, open manufacturing with initial focus on desktop 3D printer based on FFF. The slicing method provides deposited variable-width segments in an organized and replicable filling strategy, resulting in mechanical properties variations in specific regions of a part. It was implemented and evaluated experimentally and indicated potential applications in parts manufactured by the additive process based on extrusion, which requires local flexibilities. Originality/value This paper presents a new alternative method for application in an open additive manufacturing context, specifically for additive extrusion techniques that enable local variations in the material flow. Its potential for manufacturing functional parts, which require flexibility due to cyclic loading, was demonstrated by fabrication and experimental evaluations of parts made in acrylonitrile butadiene styrene filament. The changes proposed by AltPrint enable geometric modifications in the response of the printed parts. The proposed slicing and filling control of parameters is inserted in a context of design for additive manufacturing and shows great potential in the area of product design.
