Investigation into the Teaching Reform of 3D Printing Module for Engineering Training in Colleges and Universities

3D printing technology is called the “third industrial revolution”, and mastering 3D printing technology is crucial for engineering students. In the practical teaching of 3D printing module, teachers should highlight the important status of the module, make clear the cross-compatibility of technology, moderately broaden the teaching content to clearly explain the structure of 3D printing materials, introduce the cutting edge of technology to stimulate the interest of students, and enhance the teaching effect with the help of online and offline hybrid teaching methods.
