Abstract
Additive Manufacturing (AM) is a manufacturing technique that offers numerous advantages over traditional methods of production, including the ability to produce complex parts with high precision and quality while reducing manufacturing time and cost. In the production of metallic parts, Wire Arc Additive Manufacturing (WAAM) stands out among the various AM techniques. In this method an electric arc is used to melt the metallic raw material and deposit it layer by layer, forming the desired part. WAAM is a complex process that involves numerous variables that influence the finish quality as well as the mechanical and metallurgical properties of the manufactured part. Among the variables, the deposition rate of the additive material, the displacement speed of the torch, and the metal transfer mode, among others. In addition to these considerations, the cooling process during the metallic deposition is critical because it can significantly affect the microstructure and production time of the parts. Proper temperature control during the WAAM process can reduce the occurrence of deformations, cracks, and porosities, improving the surface quality and mechanical strength of the parts. The implementation of a microcontroller system for liquid level control in a submerged cooling process is interesting to WAAM, because it allows the improvement and optimization of the process, reducing material waste and increasing its productivity, since the precise control of the liquid level guarantees the effectiveness of the cooling. In this context, this work aims at the development of a microcontroller system to control the liquid level in the submerged cooling process applied to WAAM, in order to enable optimization in production of parts and temperature control. The prototype of the developed system is composed of a liquid-level sensor, a microcontroller, and an actuator that controls the liquid flow used in the cooling process. The preliminary results of this work demonstrate the efficacy of the developed prototype in the WAAM process, producing metallic forms with appreciable finishing and speed.
