“…The methodology presented in Section 3 provided a systematic analysis of existing DMLS products. The methodology is built on previous approaches [18], but the novelty is the use of functional analysis to identify DMLS features used to solve the product functions. The functional analysis enabled the solution-neutral representation of analysed products, and thus easier comparison of DMLS enabled form and solutions used to solve a block of functions or individual functions.…”

“…During the product development process, designers use different sources of design knowledge formalised through various constructs such as principles, heuristics, rules, and guidelines [27]. In this research, the extracted design knowledge will be formalised in the form of Design Principles (DPs) as it is a construct with an appropriate level of abstractness for the conceptual design phase [28] and has been used previously for the similar intended purpose [16,18]. Hence, Fu et al's formal definition of DP has been used: "Design principle is a fundamental rule or law, derived inductively from extensive experience and/or empirical evidence, which provides design process guidance to increase the chance of reaching a successful solution" [27].…”

“…The protocol used is made of multiple steps (Fig. 1) and is derived from existing protocols [16,18,31] found in the literature. The three key phases of the protocol are the collection of data, data analysis and extraction of patterns and formulation of theory based on the identified patterns [27].…”

“…Similarly, the conception of a broader AM design principles repository based on functional classification was developed by Valjak et al [18], while Watschke et al [19] developed a function-flow matrix containing 41 design principles based on the multi-material AM. Blösch-Paidosh and Shea [20] formed process-independent design heuristics that store AM knowledge needed to conceptualise a new product.…”

“…As shown, the DfAM approaches for conceptual design come in various forms, most often as design heuristics and principles. Some of the approaches are process independent ( [14,18,20]), and others are focused on a particular AM technology ( [15,19]). Due to their broadness, these tools are suitable for conceptual design and can be used to conceptualise metal AM products.…”

Additive Manufacturing (AM) brought new design possibilities and freedom to the product design process. However, as the existing design rules and design limitations do not apply to the AM, designers require new methods and tools to utilise the full potential of AM. The stated is especially noticeable in the design of metal products made with AM, particularly with the Direct Metal Laser Sintering (DMLS) process. The research proposes a methodological approach for analysing the existing DMLS products made with DMLS to extract design knowledge. The methodology is applied to the pool of DMLS from which 15 design principles are extracted that formalise design knowledge about DMLS. The design principles are intended to be used in the early design stages of the design process as a source of design knowledge and inspiration for conceptualising new and innovative products that will be made using DMLS.

This study addresses the paradoxical tensions that arise during additive manufacturing (AM) implementation for circular economy goals in the healthcare sector. Using the lens of paradox theory, this study identifies four competing priorities that stakeholders may encounter while adopting AM. Focus group discussions among 12 industry experts from the healthcare supply chain were conducted to verify the paradoxes. Semi-structured interviews were then conducted with 10 industry experts to derive the solutions to manage these tensions from an Industry 5.0 perspective to achieve the full benefits of AM. This study expands paradox theory into the AM literature and provides a novel ‘both/and’ perspective (i.e. a pluralistic rather than a dualistic perspective) to look at emerging tensions encountered while implementing AM in the healthcare sector. This perspective will help decision-makers realise that these tensions can be managed over time to turn them into creative, rather than destructive, forces.

The application of additive-manufactured cores and molds is of great interest for complex cast components. Nevertheless, several challenges still exist in utilizing binder jetting in the multi-step additive manufacturing process for foundry applications to its fullest extent. This contribution shows methods that facilitate the use of 3D-printed sand molds and cores in casting series applications. The binder jetting process itself is assessed from an overall process chain perspective to highlight the benefits of its application in series production. The challenges associated with automating mold cleaning for highly complex casting contours are depicted. In particular, employing the method of cleanable mold partitioning is shown to enhance the automation level of the overall process. Mold design tailored to 3D printing is demonstrated to contribute to overall cost and time savings in enhanced core packages. Topology-optimized, lightweight part designs involving complex freeform surfaces may require mold partitioning associated with laborious burr removal processes. A new approach in answer to the shortage of skilled workers in the harsh and hazardous foundry environment is shown. Implementing motion tracking technology is demonstrated to enable economical automated burr removal for minor quantities or high variant diversity in the future foundry. All the methods shown are of great importance for introducing printed core packages into series production.
