Research on “slice” layer height and width additive manufacturing by maskless localized electrodeposition method

Abstract

Maskless localized electrodeposition additive manufacturing is a novel non-thermal metal additive manufacturing technology, the resolution and quality of the parts manufactured of the additive manufacturing process are determined by the layer height. In order to study the layer height data of maskless localized electrodeposition, the effect of main process parameters such as inter-electrode voltage, electrode scanning rate, electrode gap, and pulse duty cycle on experimental results were studied by the controlled variable method and orthogonal experiment method. The research results show that the electrode scanning rate and voltage have a greater influence on the layer height, and the duty cycle has a smaller influence on the layer height, a smaller electrode spacing will lead to deposition failure. The faster the electrode scanning speed, the smaller the layer height. In the voltage (4V), duty cycle (50%), interelectrode gap (IEG) (30μm), frequency (5KHz), scan rate (20μm/s), the layer height is 1.8μm and the deposition efficiency is higher and surface morphology is better.
