From concept to reality: integrated design methodology using sketches, renderings, technical drawings, and 3D printing

Abstract

Introduction. Design has evolved with the incorporation of technologies that optimize the representation and materialization of ideas. From manual sketches to renderings and 3D printing, these tools allow a more accurate and realistic visualization. This research proposes a comprehensive methodology that combines sketches, digital representations, technical drawings, and 3D printed models to improve the understanding and execution of projects. This approach not only optimizes communication and reduces errors in the initial stages, but also integrates functional, aesthetic, and technical criteria, favoring the creation of innovative and efficient designs. Objective. To propose an integral methodological model that optimizes the use of tools in design, from conceptualization to the materialization of the project. It seeks to demonstrate that the combination of traditional and digital techniques improves conceptual development and ensures greater fidelity between the initial idea and the result. Methodology. This research follows a practical approach based on the analysis and creation of a real object, going through each stage of the design process. It starts with sketches to explore shapes, proportions, and composition, then incorporates technical aspects such as the selection of materials and the generation of renderings to evaluate visual configurations. Finally, the design has materialized through 3D printing. This methodology allows validating the proposed model and offering a structured guide for its application in unique design contexts. Results. The combination of manual sketching, 3D modeling, generation of technical drawings and additive manufacturing ensures a structured workflow that optimizes the accuracy, functionality, and manufacturability of the final product. Conclusion. This approach not only improves design quality and reduces errors in initial stages but also facilitates technical documentation and prototype validation. Thus, it is consolidated as a versatile and effective methodology for product development in various design and engineering contexts. General area of study: Engineering, Industry and Construction.
