Teaching 3D Printing to Kids

3D printing is a revolutionary technology that has captured the imagination of both young and old alike. For kids, it offers an exciting opportunity to explore creativity, problem-solving, and STEM (Science, Technology, Engineering, and Mathematics) concepts in a hands-on, engaging way. In this article, we'll provide a comprehensive guide on how to start teaching 3D printing to kids. These activities will not only nurture their technological skills but also spark their enthusiasm for the world of innovation and design.

1. Exploring the Basics:

To begin, introduce children to the fundamental concepts of 3D printing:

  • Understanding 3D Modeling: Start by explaining what 3D modeling is and how it forms the foundation of 3D printing.
  • Materials and Printing Processes: Describe the materials used in 3D printing, such as PLA or ABS, and how printing works layer by layer.
  • Safety Precautions: Stress the importance of safety, including using proper protective gear, especially when handling 3D printers.

2. Selecting Age-Appropriate Tools and Software:

Choose suitable 3D printers, modeling software, and resources that match the children's age and skill level. Some kid-friendly 3D printers and software are designed with simplicity in mind, making it easier for young learners to grasp the basics.

3. Hands-On Designing:

  • Tinkercad: Tinkercad is a user-friendly, web-based 3D modeling platform ideal for beginners. Kids can create simple designs by dragging and dropping shapes.

  • Create Simple Projects: Start with uncomplicated designs, like keychains or name tags, to help children understand the design-to-print process.

4. Printing and Troubleshooting:

  • Supervision: Always supervise children when they’re using the 3D printer to ensure safety and proper operation.
  • Troubleshooting: Teach them basic troubleshooting skills to address common issues, such as bed adhesion or print errors.

5. Educational 3D Printing Projects:

Engage kids in fun and educational projects to make learning 3D printing exciting:

  • Custom Puzzles: Have kids design and print their own puzzles, which promotes spatial thinking.
  • Replicating Objects: Challenge them to recreate everyday objects, fostering problem-solving skills.
  • STEM-Themed Projects: Encourage the creation of STEM-related models like simple machines, planetary systems, or famous landmarks.

6. Collaborative Learning:

Promote collaboration and peer learning. Encourage kids to work together on larger projects, combining their ideas and skills.

7. Field Trips and Guest Speakers:

Organize visits to local makerspaces or invite experts in 3D printing to inspire children with real-world applications and possibilities.

8. Showcasing Their Work:

Create a platform for kids to showcase their 3D-printed creations, such as an exhibition at school or an online portfolio.

9. Continuous Learning:

Encourage children to keep exploring 3D printing. As they gain more experience, introduce them to advanced concepts and software for more complex designs.

10. Resources for Further Learning:

Provide a list of recommended books, websites, and online courses that kids and their parents can explore to enhance their 3D printing knowledge.


Teaching 3D printing to kids can be an immensely rewarding experience. By following this guide, you can nurture their creativity, problem-solving skills, and understanding of technology while sparking a lifelong passion for innovation and design. Remember, the journey is as important as the destination, and the process of learning is where young minds truly flourish. Start their 3D printing adventure today!
