Abstract

The manufacture of parts via fused deposition modelling (FDM) is inhibited by a lack of understanding of the manufacturing process, resulting in parts having unreliable mechanical properties. Correspondingly, this paper considers the incorporation of capability profiles (CPs) for FDM as a solution. The evolved requirements of CPs for FDM are considered and the necessary process information that would be incorporated within them is presented. A review of existing literature of the effect of process parameters on mechanical properties of FDM parts identifies process variability and the effects of shape and scale as areas insufficiently studied. To address this, tensile tests are conducted revealing: 1) variation (26%) in identical test specimens' UTS; 2) that properties do not scale linearly with specimen size; 3) that cross-sectional shape directly impacts mechanical performance. These results are used to define the parameters required for a capability profile for FDM and subsequently demonstrate its functionality.

走向设计的民主化:FDM的广义能力模型

由于缺乏对制造工艺的了解，通过熔融沉积建模(FDM)制造零件受到抑制，导致零件具有不可靠的机械性能。相应地，本文考虑将能力轮廓(CPs)纳入FDM作为一种解决方案。考虑了FDM中CPs的演变需求，并提出了将被纳入其中的必要过程信息。对工艺参数对FDM零件机械性能影响的现有文献的回顾表明，工艺变异性以及形状和尺寸的影响是研究不足的领域。为了解决这个问题，进行了拉伸试验，揭示了:1)相同试件的UTS变化(26%);2)性能不与试样尺寸成线性比例;3)截面形状直接影响力学性能。这些结果用于定义FDM能力概要文件所需的参数，并随后演示其功能。

期刊介绍： The objective of IJASM is to establish an effective channel of communication between academia, industry and persons concerned with the design and development of systems. Change is eternal and perpetual, irrespective of type of system. Systems created in the course of the advance of human civilization need to be functionally and operationally sustainable amid changes in technological, political, socio-economical, financial, cultural and other environmental challenges. IJASM aims to promote and harmonize knowledge developments in the emerging fields of agile systems research, sustainability and vulnerability analysis, risk assessments methodologies, complex systems science, e-organisation and e-supply chain management, with emphasis on the international dimension, particularly breaking cultural barriers, and on national contexts, globalisation and new business practices. As such, we aim to publish papers presenting new research, innovative theoretical approaches, changes in agile management paradigms, and action (both examples of successes and failures as long as there are important lessons to be learned) from leading scholars and practitioners. Papers generally fall into two broad categories: those grounded in theory and/or papers using scientific research methods (e.g., reports of original empirical studies, models, critical reviews of existing empirical research, theory pieces that clearly extend current thinking); and those focusing on innovative agile approaches that are based on well reasoned extensions of existing research, experiential knowledge, or exemplary cases (e.g., thought pieces, case studies, etc).
