Abstract
The Department of Energy and Mechanical Sciences of the University of the Armed Forces (ESPE), together with the "Quiquis" Maintenance Battalion, a unit of the Ecuadorian Army, developed a reverse engineering project for several non-lethal kinetic launchers currently in use in the country. This project will be used to design and manufacture non-lethal weapons for use in riots in prisons. In the first stage of the project, led by Engineer Sebastián Olivo, a research project yielded results on stresses, deformations, safety factors, analysis of the propulsion mechanisms, and exploded views of the non-lethal weapon. In this second stage, the non-lethal weapon and its accessories were manufactured using the nationally available technological support, such as CNC machines, a high-speed precision lathe Model S430 x 1000G, and 3D printers. Likewise, the materials used for its manufacture are available over-the-counter and were: 7075-T6 aluminum alloy for machining the body of the non-lethal weapon. This material allows the parts to withstand high fatigue due to its hardness and high density. The manufacturing time of the non-lethal weapon was approximately 168 hours. Subsequently, firing tests were conducted with talc projectiles, thus validating the functionality of this work.

As an officer of the Ecuadorian Army, I have a solid academic and professional background. I graduated with a degree in Military Sciences and as a Mechanical Engineer, complementing my education with a Master's degree in Occupational Risk Prevention. Currently, I serve as Head of the Army Maintenance Center, where I apply my technical and leadership skills. My research focuses on solving institutional needs, leveraging my experience in mechanical engineering to develop practical and effective solutions. This article arises from the need to address a specific challenge within the institution, using my knowledge to improve the processes and efficiency of military maintenance.

I am a Mechanical Engineer graduated from the University of the Armed Forces ESPE in 2002. I obtained a Master's degree in Design, Production and Automation at the National Polytechnic School in 2015.
Later, I obtained a PhD in Mechanical Engineering at the University of Porto, specializing in intermetallic alloys.
Since 2007, I have worked as a researcher and teacher at ESPE, initially on military projects.
Between 2012 and 2014, I was Head of the Manufacturing Processes Laboratory.
During my PhD, I collaborated with INEGI in Portugal in areas such as casting and additive manufacturing.
I am a member of the Fundação para a Ciência e a Tecnologia in Portugal and I am involved in advanced research projects.
Currently, I focus on the optimization of production processes, especially in chip cutting and 3D printing.
My experience includes prototype development and system improvement in multidisciplinary teams.
My goal is to encourage applied research in subtractive and additive manufacturing at ESPE
