3D Printing Practical Teaching Based on Combination of Forward and Reverse Design
A 3D printing practical teaching project based on assembly parts as the carrier,the combination of forward and reverse design as the idea,and the project-teaching as the basis is developed to guide students to innovate independently and pay attention to product quality.In the practical process,some parts are designed forward and printed to form,while the remaining parts are designed backward and printed to form.At last,all parts are assembled to obtain a complete assembly model.The teaching implementation effect shows that the product scrap rate in the practical process has significantly decreased,while the students'classroom participation has significantly increased.The teaching method based on the combination of forward and reverse design breaks through the traditional teaching approach of 3D printing practice.It can exercise students'comprehensive abilities such as project management,independent innovation and proactive problem-solving,and implement the cultivation of students'quality awareness.
