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. 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. How does this compare to traditional hand drawings? Can students actually enhance spatial abilities more through computer drawings and 3D-printed models rather than hand drawings? Research suggests that although hand drawings are still a component of the learning process, newer technologies can now enhance a learner's ability to increase spatial ability, particularly spatial visualization.
