Abstract

In this paper the authors present the use of 3D printing to create a physical model that clarifies for students the triple orthogonal projection of a point, an essential concept from descriptive geometry. The physical model features a sphere representing a point in 3D space, along with three plates hinged together and mounted at right angles to represent the projection planes. The 3D printing offered the required precision for component fabrication while a sphere imagining a light spot facilitated projection interpretation. The possibility to rotate the plates facilitated comprehension of the point’s draught, resulting in enhanced comprehension of the geometric relationships between the projections of that point. This physical model proves that 3D printing can be used to modernize teaching materials in descriptive geometry.
