Special Issue Information

Dear Colleagues,

Additive manufacturing is different from traditional manufacturing as it allows a part to be built layer-by-layer. Wire-based additive manufacturing is attracting significant attention in industry and academia due to its ability to harness the benefits of additive manufacturing to produce large components of medium geometric complexity. Uniquely, wire-based additive muanufacturing technology combines the use of a wire and energy source to build components in a layer-by-layer approach, both of which can offer significant cost savings compared to powder and alternative fusion sources, respectively. Meanwhile, a high deposition rate is provided, whilst also allowing significant material savings compared to conventional manufacturing processes. Therefore, this topic focuses on the latest developments in wire-based additive manufacturing technology; its scope is to explore this technology and the research into microstructure characterization and mechanical performance. This topic also outlines the primary development trend, engineering application, and numerical simulation of wire-based additive manufacturing methods. In terms of the deposition process, it covers various wire-based deposition processes, including traditional methods and emerging techniques, such as arc, laser, electron beam, friction stir, etc. Submitted articles should cover truly novel methods or technology in the field of wire-based additive manufacturing and processes that can effectively improve the deposited defects, microstructure, performance, and residual stress of components.

A novel controller, employing a variable-structure single-neuron adaptive PSD (proportional integral derivative) approach, was proposed for regulating the deposition width variation in the Directed Energy Deposition-Arc (DED-Arc) layer. During experimental trials, the deposition speed was chosen as the manipulated variable, while the width of the deposition layer served as the measured parameter. To facilitate controller design, a vision sensor was custom-designed to accurately detect the width of the deposition layer. The captured image of the deposition layer’s dimensions enabled the precise determination of the deposited thickness, forming the basis for subsequent controller development. In performance assessments, deliberate interference was intentionally introduced into the deposition current, deposition layer height, and the targeted deposition layer width. The assessment involved the controlled deposition of ten-layer components, focusing on width regulation for each deposition layer. The results demonstrate that the proposed controller significantly enhances the deposition process stability, particularly within a range of desired deposition widths from 7.5 mm to 8.3 mm.
