Abstract: A liquid marble is a droplet of liquid coated with microparticles or nanoparticles. A novel method of localised electrochemical co-deposition using liquid marbles and the feasibility of application of this method in additive manufacturing/micro-repair is discussed. Controllability of the transportation of liquid marbles to any desired location by pick and place technique has been demonstrated by depositing a 3 × 3 grid pattern with 1mm period using an in-house built CNC setup. An experimental study was conducted to study the effect of three process parameters viz. duty factor, reaction time and volume of electrolyte on the height of the deposit and ANOVA was performed at 95% confidence level. It was found that the duty factor was the most significant process parameter.

Keywords: co-deposition; design of experiments; electrochemical additive manufacturing; liquid marble.
