Using 3D Printing to Teach Orthographic Projection

Sign up or log in to save this to your schedule and see who's attending!

A key aspect of many trades is the ability to visualize three-dimensional objects in two-dimensional space and to work backward from standard prints which depict objects in orthographic projection to construct three-dimensional parts. This type of spatial visualization is a developed skill and so differs from principles or terms which can be understood from texts and lectures. Because of this, students often struggle when first learning to read prints and instructors in the Machine Technology Department at Laney College have expended much energy to improve teaching techniques. The department’s Engineering Drawings for Machinists, Welders, and Industrial Maintenance Technicians course uses "Print Reading for Industry" by Goodheart-Wilcox Publisher as a textbook. The textbook is a reasonably effective teaching aid and its main strengths are the many exercises at the end of each chapter and the large format industry prints which come with the main text. Practice and repetition is enough for some students, but experience has shown that all students (and certainly those who are kinesthetic learners) benefit from three-dimensional representations or, even better, physical replicas of parts. This presentation will address the usage of cutting-edge design and manufacturing technologies, primarily Computer-Aided Design and 3D Printing, to develop students’ spatial visualization abilities.
