Research on 3D Printing and Its Application in CAD Teaching

Abstract

3D printing is a rapid prototyping technology in recent years. Computer aided design (CAD) combining with 3D printing in university is helpful for students to understand the design work. The history and characteristics of 3D printing technology were introduced. The technology and material used in 3D printer was summarized. The application of 3D printing technology in teaching was studied. Combining 3D printing technology and CAD design cases is helpful for students to understand the designed model directly and to master the three-view drawing of objects intuitively. Integrating 3D printing technology into mechanical design competition is an effective means to promote teaching effect. Apply 3D printing into CAD teaching could improve students’ subjective initiative in learning, expand students’ innovative thinking, and improve teaching quality.
