ABSTRACT

Currently, additive manufacturing (AM) technology has received significant attention from both academia and industry. AM is characterized by fabricating geometrically complex components in a layer-by-layer manner, and greatly reduces the geometric complexity restrictions compared with traditional manufacturing. As AM is no longer limited to the normal three degrees of freedom (DOF) (three-axis) systems, there are many new multi-DOF AM machines been developed with various aims. It is, therefore, necessary that a review of the topic with regard to multi-DOF AM is performed for future AM system development. This paper, focuses on reviewing publications related to multi-DOF AM according to the number of DOF on an AM machine. The major part of the paper aims to inspire both researchers and engineers to further develop and improve multi-DOF AM systems to achieve different goals. The final part of the paper discusses the findings together with future research directions.

摘要

当前，增材制造（AM）技术已受到学术界和工业界的极大关注。AM的特征在于，可以逐层制造几何形状复杂的组件，与传统制造相比，大大降低了几何形状复杂性的限制。由于AM不再局限于常规的三自由度（DOF）（三轴）系统，因此有许多新的多自由度AM机器已经针对各种目的进行了开发。因此，有必要对有关多自由度AM的主题进行审查，以用于将来的AM系统开发。本文主要根据AM机器上的DOF数量，回顾与多自由度AM相关的出版物。本文的主要部分旨在激励研究人员和工程师进一步开发和改进多自由度AM系统，以实现不同的目标。本文的最后一部分讨论了研究结果以及未来的研究方向。
