Abstract


This paper discusses how to use 3D printing to exhibit double orthographic projection and actualize a functional, didactic physical model using FDM technology. Two articulated plates enable positioning at a 90° angle and folding into a common plane, effectively illustrating geometric projections. Flexible cylinders and a sphere symbolize the geometric point, facilitating the analysis of its position relative to projection planes. A spotlight enhances projection visibility and supports better visual understanding. The optimized technical parameters, such as temperature, print speed and the height of the deposited layer, ensured the accuracy of the obtained components. Results confirm the efficiency of 3D printing in clarifying descriptive geometry principles and developing an interactive and precise educational tool.
