直接数字化制造是当前制造领域的热点之一。随着廉价的三维打印机的引入，直接数字制造似乎成为一种新的制造范式，对社会产生了完全不同的影响；然而，这将如何影响社会以及范式之间的差异尚不清楚。在此背景下，本文从不同角度对直接数字化制造进行了全面分析，并与各种传统制造范式进行了比较。作者正在用社会的观点来看待、描述和分析这个主题，而不是传统的制造业观点。为了更好地理解直接数字化制造的起源，本文描述了可用技术的分类和历史背景。此外，将直接数字化制造作为一种范式，与工艺生产、大规模生产和大规模定制进行了分析和比较。为了更好地了解这一技术，我们收集和分析了直接数字化制造在社会、经济和环境方面的可持续性。详细的案例研究深入论证了直接数字化制造和大规模生产的能源使用差异。根据目前的研究，直接数字制造有可能结合其他生产模式的优势，并对可持续发展产生积极影响；然而，在技术和社会方面都有一些挑战需要克服。社会方面的挑战可能是生活方式的改变，这会影响到就业市场、工作环境、废物管理等。(C) 2015 Elsevier Ltd.版权所有。
One of the hot topics currently in manufacturing domain is direct digital manufacturing. With introduction of cheap three-dimensional printers, the direct digital manufacturing seems to become a new manufacturing paradigm with an entirely different impact on society; nevertheless how this will impact the society and the differences between the paradigms are unclear. According to this background, this paper presents a comprehensive analysis of direct digital manufacturing from different perspectives in comparison to various traditional manufacturing paradigms. Authors are using a societal viewpoint to see, describe and analyse the subject instead of traditional manufacturing viewpoint. For the better understanding of direct digital manufacturing origins, a classification and historical background about available techniques are described. Furthermore, direct digital manufacturing as a paradigm is analysed and compared with craft production, mass production and mass customisation. Direct digital manufacturing's sustainability aspects related to social, economical and environmental dimensions are gathered and analysed for a better insight of this technique. A detailed case study demonstrates the energy use differences of direct digital manufacturing and mass production in depth. According to the present work, direct digital manufacturing has the possibility of combining the advantages of the other production paradigms and can have a positive impact on sustainable development; yet, there are several challenges to overcome both in technical and sociality aspects. A challenge within the social aspects can be the life style changes which can impact the job market, working environment, waste management and more. (C) 2015 Elsevier Ltd. All rights reserved.
