Abstract: In order to cultivate students interest in learning, broaden their horizons, exercise design and innovation ability, and help students to understand the development trend of 3D printing technology, this paper introduces the construction of 3D printing experimental teaching based on fused deposition modeling technology.Based on the basic requirement and process of the experiment,students can basically master the fused deposition modeling type 3D printing technology, and according to the characteristics of material science and engineering discipline, we set up the advanced requirements and experiments, so that the students have an understanding of the preparation, processing and application of 3D printing material.By the construction of experimental teaching, the project can broaden the horizons of students, effectively improve the students ability in design and innovation research.
