Application of 3D printing to the intersection of surfaces learning in a descriptive geometry course

Abstract

This work on surfaces intersection intends to facilitate learning on this subject to the student, something that, from teaching experience, has been found to be difficult to understand and to visualize. The student’s ability to resolve or discriminate spatially defined features is a very important requirement when it comes to understanding certain types of intersections of surfaces, due to its wide application in the engineering framework. This work shows that the use of 3D printed models facilitates learning the dihedral system and improves the performance of the student on problem solving.
