This document appears to be a presentation on 3D printing created by students. It includes the results of a survey on people's awareness and understanding of 3D printing. The survey found that most people have heard of 3D printing but know few applications. It also found many believe 3D printing was invented in the 1990s rather than 1980s and were unfamiliar with its history. The presentation analyzes the survey results and assigns tasks like creating the mind map, survey, analysis and video to the different student contributors.
