Item Análisis y validación del prototipado e impresión 3D para un sistema de tratamiento de aguas residuales a escala de laboratorio(Universidad Santiago de Cali, 2025) Narváez Gómez, Juan Andrés; Cardénas Talero, Jose Luis (Director)The objective of this study was to design, build and validate a 3D printed educational module that simulates the main processes of a domestic wastewater treatment plant (WWTP) for educational purposes. The prototype was developed from the real system of the Cachipay WWTP, representing the aeration, sedimentation and sludge dewatering stages, by means of computer-aided design (CAD) in OnShape® and fused material deposition (FDM) fabrication using polylactic acid (PLA). A modular and scaled approach was adopted to facilitate visualization of the water path and encourage active learning in training environments. Evaluation of the prototype included functional hydraulic flow tests and technical tests to determine its durability, mechanical strength, mass loss and structural deformation after 12 weeks of continuous exposure to clean water. A 5% variation in each indicator was recorded, without compromising its structural integrity or pedagogical functionality. In addition, PLA was compared with materials such as PETG and ABS, highlighting its advantages in sustainability, ease of printing and educational applicability. The results validate the viability of the model as a replicable, accessible and effective tool for teaching water treatment processes in technical and technological contexts.
