“…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].…”

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.

A wide range of tools simplify product development, e. g. Knowledge-Based Engineering Systems (KBES). Many KBES draw on knowledge derived from DfX methods. The knowledge of these methods is often available in varying degrees of detail, arising from the explicit knowledge of experts and scientists. When passing on knowledge, product developers often do so in the form of easy-to-understand rules of thumb, so-called design heuristics (DH). However, published DH do not offer sufficient clarity and usability to be integrated in daily engineering practice. This paper describes the development of a standardized notation form to make DH describable as a first step towards automated integration into KBES and towards integrating implicit knowledge of designers in future MBSE models.

“…Commonly used design tools to support DfAM and to help designers consider manufacturing costs and constraints include lists of design principles and CAD-based software (Pradel et al 2018; Valjak & Lindwall 2021). Another commonly used tool, the Design for Additive Manufacturing Worksheet (Booth et al 2017), lists design principles along with a scoring system to allow designers to evaluate a design’s suitability for AM.…”

Improving designers’ ability to identify manufacturing constraints during design can help reduce the time and cost involved in the development of new products. Different design for additive manufacturing (DfAM) tools exist, but the design outcomes produced using such tools are often evaluated without comparison to existing tools. This study addresses the research gap by directly comparing design performance using two design support tools: a worksheet listing DfAM principles and a manufacturability analysis software tool that analyzes compliance with the same principles. In a randomized-controlled study, 49 nonexpert designers completed a design task to improve the manufacturability of a 3D-printed part using either the software tool or the worksheet tool. In this study, design outcome data (creativity and manufacturability) and design process data (task load and time taken) were measured. We identified statistically significant differences in the number of manufacturability violations in the software and worksheet groups and the creativity of the designs with novel build orientations. Results demonstrated limitations associated with lists of principles and highlighted the potential of software in promoting creativity by encouraging the exploration of alternative build orientations. This study provides support for using software to help designers, particularly nonexpert designers who rely on trial and error during design, evaluate the manufacturability of their designs more effectively, thereby promoting concurrent engineering design practices.
