Designing and Printing a 3D printed Keyring

Lesson Steps:

Introduction to 3D Design

Introduction

• Discuss what 3D printing is and its applications.
• Show examples of 3D printed objects, focusing on keyrings.

Software Overview

• Introduce the 3D design software. Provide a brief tutorial on how to navigate the interface.
• Demonstrate basic shapes and tools used to create a simple keyring design.

Guided Practice

• Students will create their first basic shape (e.g., a simple rectangle) in the software.
• Assist students as they experiment with different shapes.

Design and Creation

Designing the Keyring

• Explain keyring dimensions (e.g., length, width, thickness).
• Students will design their own keyring. Encourage creativity (adding initials, simple shapes, etc.).
• Remind them to keep the design practical for 3D printing (avoid intricate details).

Peer Review

• Students pair up to share their designs and give feedback to each other.

Finalising Designs

• Students make adjustments based on feedback and finalize their designs.
• Save files in the appropriate format for 3D printing (e.g., .STL).

Printing and Reflection

Preparing for Printing

• Teach students how to prepare their files for printing (slicing software).
• Discuss settings like infill, layer height, and print speed.

3D Printing

• Print keyrings. Depending on the number of printers and designs, this may take additional time.
• While printing, students can work on a reflection sheet about their design process.

Reflection and Cleanup

• Once printed, discuss what went well and what could be improved in their designs.
• Clean up workspaces and ensure the area is ready for the next class.
