Optimal Material

Purpose The purpose of this paper is to implement the generative design as an optimization technique to achieve a reasonable trade-off between weight and reliability for the control arm plate of a double-wishbone suspension assembly of a Formula Student race car. Design/methodology/approach The generative design methodology is applied to develop a low-weight design alternative to a standard control arm plate design. A static stress simulation and a fatigue life study are developed to assess the response of the plate against the loading criteria and to ensure that the plate sustains the theoretically determined number of loading cycles. Findings The approach implemented provides a justifiable outcome for a weight-factor of safety trade-off. In addition to optimal material distribution, the generative design methodology provides several design outcomes, for different materials and fabrication techniques. This enables the selection of the best possible outcome for several structural requirements. Research limitations/implications This technique can be used for applications with pre-defined constraints, such as packaging and loading, usually observed in load-bearing components developed in the automotive and aerospace sectors of the manufacturing industry. Practical implications Using this technique can provide an alternative design solution to long periods spent in the design phase, because of its ability to generate several possible outcomes in just a fraction of time. Originality/value The proposed research provides a means of developing optimized designs and provides techniques in which the design developed and chosen can be structurally analyzed.

Purpose This paper aims to review the latest management developments across the globe and pinpoint practical implications from cutting-edge research and case studies. Design/methodology/approach This briefing is prepared by an independent writer who adds their own impartial comments and places the articles in context. Findings 3D printing is big business, and it is growing fast. While there is some adoption of the technology in industry, the vast majority is occurring at home, with users. These user entrepreneurs are carving their own path into business, providing products and services to a growing customer base in a way that large incumbent organizations cannot. The innovative and adaptable nature of these user entrepreneurs perfectly fits the 3D printing market, but with such a diverse marketplace and large number of competitors, a competitive advantage is being sought. Holzmann et al. (2017) look at the use of business models to ascertain whether they can provide this desired advantage in the 3D printing user market. Practical implications The paper provides strategic insights and practical thinking that have influenced some of the world’s leading organizations. Originality/value The briefing saves busy executives and researchers hours of reading time by selecting only the very best, most pertinent information and presenting it in a condensed and easy-to-digest format.

Metal 3D Printing

Purpose With the overarching idea of disruptive technology and its effects on business, this paper focuses on how companies strategically consider meeting the challenge of a disruptive technology such as additive manufacturing. The purpose of this paper is to describe and discuss changes in positions and roles related to the implementation of a disruptive technology. Design/methodology/approach Additive manufacturing could be expected to have different consequences for parties based on their current supply chain positions. The paper therefore investigates companies’ strategies related to various supply chain positions and does so by departing from a position and role point of view. Three business cases related to metal 3D printing - illustrating sub-suppliers, manufacturers and logistics firms - describe as many strategies. Data for the cases were collected through meetings, interviews, seminars and secondary data focusing on both current business activities related to additive manufacturing and scenarios for the future. Findings The companies attempted to defend their current positions, leading to new roles for them. This disconnects the change of roles from that of positions. The changed roles indicate that all parties, regardless of supply chain positions, would move into competing producing roles, thereby indicating how a disruptive technology may disrupt network structures based on companies’ attempts to defend their positions. Originality/value The paper contributes to previous research by reporting a disconnect between positions and roles among firms when disruption takes place. The paper further denotes how the investigated firms largely disregarded network consequences at the disruptive stage, caused by the introduction of additive manufacturing. The paper also contributes to research on additive manufacturing by including a business dimension and linking this to positions and roles.

Am Processes

The continuously decreasing life cycle of modern products leads to new challenges for product development. Additive manufacturing (AM) processes are able to support faster development by rapid production of samples and prototypes. However, the material properties of components produced by common (plastic-) 3D-printers are often insufficient for functional prototyping. A well-established way to improve the properties of plastics is the embedding of reinforcing fibers. Thus, this paper shows a method for fiber-reinforced 3D-printing. Through this combination, several restrictions of conventional composite production can be eased and additional freedoms of design are gained. To support the design of such parts, an adapted design methodology for fiber-reinforced 3D-printing is developed.

Abstract Robustness, compactness, and portability of tensegrity robots make them suitable candidates for locomotion on unknown terrains. Locomotion is achieved by breaking symmetry and altering the position of center-of-mass to induce “tip-over”. The design of curved links of tensegrity mechanisms allows continuous change in the point of contact (along the curve) as compared to discontinuities in the traditional straight links (point contact) which induces impulse reaction forces during locomotion. The illustrated curve-link tensegrity robot achieves smooth locomotion through internal mass-shifting. Additionally, this tensegrity robot displays folding and unfolding. Introduced is a design methodology for fabricating tensegrity robots of varying morphologies with modular components created using rapid prototyping techniques, including 3D printing and laser-cutting. The techniques are utilized to fabricate simple tensegrity structures, followed by locomotive tensegrity robots in icosahedron and half-circle arc morphologies.
