The 3Doodler is a 3D printing pen that allows students to create three-dimensional objects by drawing with heated plastic that quickly hardens into solid shapes. It provides a hands-on way to explore design, engineering, and creativity without needing a traditional 3D printer. Students can build structures, models, and artistic designs while developing spatial thinking and problem-solving skills.
