Unit: “Introduction to 3D Design and 3D Printing”

The “Introduction to 3D Design and 3D Printing” unit engages students aged 13-16 in understanding the complete process of 3D fabrication. Over 90 minutes, students integrate mathematics, physics, chemistry, material sciences, and arts to design and create a 3D-printed keyring. They start by learning the theoretical aspects of 3D printing, including using CAD software to create a 3D model. They explore geometric properties, design aesthetics, and material properties. The hands-on activity involves using CAD software to design a keyring and CAM software to prepare the design for 3D printing. Students then print their designs and evaluate the final products. This unit emphasises creativity, technical skills, and applying scientific and mathematical principles practically. It helps students understand the entire 3D printing process, from initial design to the finished object, fostering critical thinking and problem-solving skills.
