“…132 Azad et al employed Response Surface Methodology (RSM) to optimize and investigate the effects of parameters such as current, pulse-forward time, and pulse-reverse time on the thickness uniformity and hardness of copper bellows-shaped parts using pulse-reverse current. 133 Behagh et al similarly investigated the impact of various parameters in the low-frequency pulsed electroforming process, including current, pulse-on time, pulse-off time, and electrolyte temperature, with the aim of achieving uniform thickness. They employed the Taguchi method to determine the optimal parameter combination and assess parameter effects, utilizing techniques such as signal-to-noise ratio (S/ N), analysis of variance (ANOVA), and Pareto ANOVA analysis.…”

Being an unconventional technique of additive micro-manufacturing, electroforming has garnered significant interest by various industrial sectors because of its capability to offer advanced micro-manufacturing competences with high precision in achieving dimensional uniformity and replication accuracy at small scale. This paper reports a comprehensive review of the electroforming process as a microsystem fabrication technique. This process is superior compared to 3D printing, stereolithography, selective laser sintering, and fused deposition modeling etc., in many aspects due to its unique properties. It can deposit a wide variety of metals and alloys, including precious metals, making it appropriate for variegated applications in microfabrication domain. We cover the fundamental aspects of electroforming and its history followed by the current state of the art advancement, modelling associated with it, and its importance from industrial context. Additionally, we discuss the advantages and limitations of this technique and their respective microsystems applications. Finally, we conclude with a discussion on the future prospects and potential advancements in the field of electroforming contributing to micro-systems development.

In previous studies, jets were controlled by adjusting parameters such as velocity, pressure, size and shape of nozzle, and temperature. In this study, a new method of controlling electrolyte jets was proposed by introducing a constrained fluid. To analyze the effects of the constrained fluid on the jet flow field, the initial jet velocity and velocity ratio of the flow field were examined. Simulation results showed that the proposed method can avoid stray deposition caused when the electrolyte is spread on the substrate surface. The electrolyte jet could be controlled by the constrained fluid, indicating the characteristic of cyclical fluctuation. The initial jet velocity and velocity ratio had different impacts on the flow field; the former mainly affected the velocity and pressure distribution. The relationship between the velocity of flow field and initial jet velocity was observed to be linear. However, the relationship between pressure of the flow field and initial jet velocity was quadratic. The velocity ratio had a significant impact on the state of electrolyte jet. At low initial jet velocities, the electrolyte jet was not continuous at different velocity ratios. When the initial jet velocity increased, cyclical fluctuations in the electrolyte jet weakened under high velocity ratios. The electrolyte jet diameter also decreased linearly as the velocity ratio increased. The velocity and pressure of the flow field were quadratically related to the velocity ratio. This indicates that the constrained fluid had a considerable impact on the flow field and state of the electrolyte jet. Moreover, the electrolyte jet could be controlled effectively by adjusting the initial jet velocity and velocity ratio to obtain a stable and small electrolyte jet diameter.
