This document presents the design, construction, and analysis of results of the Dip Coater machine, a piece of equipment that is used to obtain thin film on various materials, using a technique that is based on the controlled immersion and extraction of a substrate into a solution. The work reports on the construction of this piece of equipment, which mainly uses a PAP engine and an Arduino Mega 2560 microcontroller, carried out in the nano-materials laboratory of the Antonio Narino University, and that involved four phases: design, prototyping, construction, and validation. The Dip Coater offers an adjustable control of parameters: immersion/extraction speed, immersion and drying times, number of immersion cycles, and immersion displacement; so in this research, we evaluated the user-machine interaction response and the behavior of the extraction speed with different masses. The reproducibility of the coatings was studied as the mass changes according to the speed of extraction. The morphological and physical-chemical characterization of a sol-gel SiO2 coating is also shown, together with the anti-corrosive properties that can be adjusted by the parameters of the Dip Coater. Finally and within this project, it was possible to design and build a competitive scientific instrument with similar characteristics to those of the commercial equipment.
