This document discusses 3D printing. It provides background on 3D printing, including its history starting in the 1980s. The document explores the principles of 3D printing and how it creates 3D objects in successive layers from a digital file. Applications of 3D printing in various industries like medical, fashion, aerospace and education are presented. Advantages of 3D printing like compact manufacturing and design freedom are outlined. The document also describes the group's research methods and an online survey conducted on 3D printing awareness and perceptions. Finally, future trends of increasing 3D printing popularity but not completely replacing 2D printing in the near future are predicted.
