Robotic-enabled additive manufacturing (REAM) is a digital manufacturing disruptive technology, a combined method that entails the use of multi-axis robotic systems and additive manufacturing.

摘要

Robotic-enabled additive manufacturing (REAM) is a digital manufacturing disruptive technology, a combined method that entails the use of multi-axis robotic systems and additive manufacturing. In comparison to other traditional additive manufacturing techniques, which are limited by a defined volume and to planar deposition of materials, REAM allows large-scale, freeform, and multi-directional deposition of materials with greater geometric freedom. This has provided new opportunities in the aerospace, biomedical, automotive, structural and creative applications and has been utilized in applications to large structural components and repair work and patient-specific implants and architecturally non-rudimentary buildings. Several technical and regulatory barriers to the adoption of the REAM into the industry exist, but among them are rigidity and precision of the path of the robot, temperature variations during metal deposition, stability of material feed during high volume assembly, software compatibility, as well as the safety of collaborative workspace between humans and robots. Moreover, the qualification programs and certified material databases are built in such a way that it may be used in highly regulated industries like aerospace and medical production. The systematic literature review of the applications, challenges, and limitations of robotic-enabled additive manufacturing are included in this article, and the research identifies the future directions of the research as the smart control, the hybrid manufacturing system, and the standardisation of the process. As indicated in the paper, a solution to these issues is necessary in the establishment of REAM as a viable manufacturing paradigm that is reliable, scalable and industrial.
