II. How 3D Printing is Changing Students' Perspectives
1. The Learning Revolution from "Passive Reception" to "Active Creation"
Under traditional education models, students are often confined to textbook knowledge with limited practical opportunities. 3D printing technology enables students to participate fully from design to production through "learning by doing," transforming abstract knowledge into tangible objects. This hands-on learning approach stimulates curiosity and desire for knowledge, increasing students' active engagement in learning.
In science education, 3D printing helps students better understand complex concepts and principles. For example, in biology classes, teachers can use 3D printing technology to create various biological models, such as cell structures and organ models. These models not only help students intuitively understand biological structures but also spark interest in life sciences. In chemistry experiments, 3D printing can be used to produce experimental instruments and equipment. Students can design and print required tools based on experimental needs, enhancing their hands-on skills and innovative thinking.
2. Interdisciplinary Integration: A Bridge Breaking Knowledge Barriers
The true charm of 3D printing lies in its ability to connect multiple disciplines. For instance, a school organizing students to design an "environmental-themed trash can" requires comprehensive application of mathematics (calculating dimensions), physics (structural strength), art (appearance design), and engineering (material selection). Through group collaboration, students not only acquire knowledge but also experience the importance of teamwork.
In the Shanghai Vocational School Student Innovation and Creativity Competition, a project titled "Intelligent Bridge" developed a 3D model customization platform that uses natural language parsing and parametric modeling to automate the generation of engineering models from creative input, improving design efficiency by 70%. This project has formed five product series—traditional culture, Chinese-style architecture, military technology, mechanical structures, and IP collaborations—and applied for four utility model patents.
3. Personalized Learning: A "Custom Tool" for Differentiated Instruction
3D printing can also customize teaching aids based on student needs. For example, younger students use plug-and-play 3D-printed building blocks to learn geometry, while older students use high-precision models to study biological cell structures. A teacher in Inner Mongolia created multi-difficulty "multifunctional chalk boxes" via 3D printing, allowing students to choose challenges based on their abilities, truly achieving "differentiated instruction."
In special education, 3D printing technology can produce numerous personalized assistive tools to help students overcome learning barriers. For instance, tactile-marked letters or words can be printed for students with reading difficulties, while assistive walking or grasping tools can be designed and printed for students with physical disabilities. These personalized aids significantly enhance learning efficiency and independence for special needs students.
III. Core Competencies Cultivated by 3D Printing

3D printing technology stimulates students' creativity and imagination, fostering innovative design capabilities. Students can create personalized toys, accessories, and more via 3D printing, honing their hands-on skills and aesthetic sensibilities. In 3D printing education, students encounter various problems and challenges during design and production, requiring them to analyze issues, find solutions, and implement them. This practical learning process cultivates problem-solving abilities and innovative thinking while fostering perseverance and teamwork.
2. Enhancement of Spatial Imagination
3D printing technology helps students better understand and apply spatial knowledge. Through 3D modeling and printing, students transform planar concepts into three-dimensional objects, making abstract ideas more visual and comprehensible. This visual learning approach not only enhances spatial imagination but also improves geometric learning abilities. By realizing their creative designs via 3D printing, students further exercise and develop their spatial thinking skills.
3. Development of Practical Skills and Engineering Thinking
3D printing technology finds its widest application in engineering education. In engineering courses, students require extensive design and experimentation, and 3D printing perfectly meets these needs. Through 3D printing, students can quickly produce prototypes for testing and improvement. For example, in mechanical engineering courses, students can design various mechanical parts and create physical models using 3D printing. This hands-on learning approach not only helps students understand engineering principles but also cultivates their design thinking and problem-solving abilities.
