Using Computer-Aided Design Software and 3D Printers to Improve Spatial Visualization

Many articles have been published on the use of 3D printing technology. From prefabricated homes and outdoor structures to human organs, 3D printing technology has found a niche in many fields, but especially education. The education of technology and engineering students has come a long way from traditional instruction using hand drawings. Although drawings may still be a part of a students learning, computer technology has been embraced in this field for several years. With the introduction of AutoCAD technical drawing programs and now 3D printing, learners can use 3D printed models to develop their spatial abilities in technology and engineering curricula. Research suggests that although hand drawings are still a component of the learning process, newer technologies can now enhance a learner\u27s ability to increase spatial ability, particularly spatial visualization. According to Gardner, spatial intelligence is one of the basic human intelligences: the ability to perceive the visual-spatial world accurately and to perform transformations on those perceptions
