- Additive Manufacturing (AM) is a fast developing manufacturing technology that brings many opportunities for the design teams at companies working with product development. One industry that has embraced this is aerospace, and more specifically within space applications (satellites and launchers). Although there are huge possibilities with this technology, there are also several challenges that need to be overcome. This paper is based on interviews, study visits and a state of the art review from the current literature. The focus of this work has been to map the opportunities and challenges with AM in space applications and to highlight the research gaps that have been found. There are few documents available that address AM and/or innovation within space applications. The results show that design for AM, as well as product and process qualification, are areas that need to be further investigated.

Konferensbidrag (refereegranskat)abstract
- With Additive Manufacturing (AM), manufacturing companies have the potential to develop more geometrically and functionally complex products. Design for AM (DfAM) has become an expression implying the need to design differently for the AM process, compared to for conventional, usually "subtractive" manufacturing methods. There is a need to understand how AM will influence the product development process and the possibilities to create innovative designs, from the perspective of the product development engineer. This paper explores the expected influence of AM on the product development process in a space industry context. Space industry is characterized by small-scale production, and is increasingly cost-oriented. There is a general belief that AM could pave the way for more efficient product development. Three companies have been studied through interviews, observations and workshops. Results show that engineers' expected implications of introducing AM in the space industry are: The involvement and influence of customers and politics on innovativeness; the need for process understanding and usage of new tools for DfAM-thinking; the need for qualification of AM processes.

Creativity in Design for Additive Manufacturing
- 2023

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Additive Manufacturing (AM) brings opportunities to create designs with complex geometries that would be impossible or very difficult to produce using conventional manufacturing technologies. While AM is widely seen as a means to increase the creativity of designers and thus innovation within organisations, there is a lack of understanding of how designers can manage their creativity while working with Design for Additive Manufacturing (DfAM). In this thesis, designers are suggested to engage in individual creativity management, which refers to a system of practices and methods for managing creativity in design practices. Ultimately, designers may need to adopt a new set of practices and methods when designing for AM. Although it is often argued that AM brings a higher degree of design freedom that allows them to ‘think outside the box’, this freedom is not limitless as AM comes with its own set of boundaries in design. It can also be difficult for designers to grasp the new limitations and possibilities offered by this manufacturing technology and to incorporate them into their design work. There are a wide range of DfAM tools, methods and frameworks available, all with different emphases, making it difficult for designers to discern directions for managing their creative work. The purpose of the research presented in this thesis is to advance the understanding of creativity in DfAM. This thesis adopts an iterative approach to qualitative research based on empirical data and literature studies. Empirical data comes from five cases across the three studies reported in the six appended papers. The majority of the collected empirical data has been gathered through semi-structured interviews designed to capture the experiences and viewpoints of designers working creatively in DfAM. Three of the cases have also been studied in a longitudinal study, providing an in-depth understanding of the progress of DfAM for each design.Based on the studies, a framework for creativity in DfAM is proposed. This framework is intended to assist designers in nurturing their creative abilities while adapting to working with AM. Initially, three important components of creativity in DfAM were identified: motivation, creative thinking, and expertise. Furthermore, three key characteristics that influence the designer in managing their creativity were then identified for each of these components. AM motivation concerns the individual designer’s goals and values in adopting AM, as well as the influence of the incentive to adopt AM within the design team, the organisation, and the industry as a whole. Three key characteristics of creativity management related to motivation were derived: collaboration, freedom for learning and defining DfAM boundaries. AM creative thinking concerns the need to reach a creative solution fit for AM. Here, the three key characteristics the visionary, realistic and analytic perspectives are derived. AM expertise is covered by both AM knowledge and AM experience. Here, the three key characteristics were identified as the knowledge domains: materials, machine and process and design.The framework presented in this thesis highlights key characteristics of creativity in DfAM and is intended to assist designers in managing their own creativity when working in additive manufacturing. The framework may help individual designers to reach their full creative potential during the adoption of AM. The identification of key characteristics also contributes to the research areas product development in engineering design, design for additive manufacturing (DfAM), and creativity in design. All three of these research areas may well benefit from the results presented in this thesis, providing a greater understanding of creativity when applied to design for additive manufacturing.

Evaluating Design Heuristics for Additive Manufacturing as an Explorative Workshop Method
- 2018
-
Konferensbidrag (refereegranskat)abstract
- It is suggested that the space industry is an ideal case for Additive Manufacturing (AM), with a low production volume and need for complex geometries. However, few engineers have experience of AM design. One way to support design engineers with limited experience of AM is the use of design heuristics, to enhance variety, quality and creativity of potential designs. This paper is based on literature studies and observations of creative workshops with companies from the space industry. Results showed that heuristics assisted designers and 8/10 heuristics was utilised during the ideation phase.

Exploring creativity management of design for additive manufacturing

Tidskriftsartikel (refereegranskat)abstract
- 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.

Innovation in a box: exploring creativity in design for additive manufacturing in a regulated industry
- 2022

Tidskriftsartikel (refereegranskat)abstract
- Additive Manufacturing (AM) is often considered to increase opportunities for creativity in design compared to traditional manufacturing methods. At the same time, it is suggested that regulated work can have a negative effect on engineers’ creative abilities, which are linked to three components of creativity (expertise, motivation, and creative thinking skills). Due to the ‘newness’ of AM, engineers need to broaden their expertise to fully exploit their creative potential while using AM. Previous research has presented support tools to assist engineers to understand the complexity of AM. A majority of such studies focus on novice engineers, rather than providing an understanding of how AM is involved in industrial practices. This paper follows three case studies from the space industry, a regulated industry, that aims to re-design a product for AM over a 21-month time period. The purpose is to explore how restrictions affect engineers’ opportunities to build AM expertise for creativity in a regulated industry. Results show the importance that case-specific aspects have on an engineer’s learning path for adopting AM. Engineers find themselves in a complex situation, with a conflict between being ‘safe’ or innovative, where innovation within such regulated industries is often compared to innovating ‘in a box’.

Konferensbidrag (refereegranskat)abstract
- The advent of additive manufacturing (AM) in recent years have had a significant impact on the design process. Because of new manufacturing technology, a new area of research emerged – Design for Additive Manufacturing (DfAM) with newly developed design support methods and tools. This paper looks into the current status of the field regarding the conceptual design of AM products, with the focus on how literature sources treat design heuristics and design principles in the context of DfAM. To answer the research question, a systematic literature review was conducted. The results are analysed, compared and discussed on three main points: the definition of the design heuristics and the design principles, level of support they provide, as well as where and how they are used inside the design process. The paper highlights the similarities and differences between design heuristics and design principles in the context of DfAM.
