Lesson 11 – Developing CAD skills

Intermediate 3D printing

Recommended age range 13 – 16

This lesson builds upon the previous lesson and developed students CAD skills in parametric modelling skills using Autodesk Fusion 360. They will learn how to design a small cable tidy for their smart phone charger cables using flexible filaments. A core feature of this lesson is the study of the mechanical properties of flexible filaments compared to rigid filaments.

Lesson contents include;

Lesson plan

  • Teaching powerpoint
  • Lesson task
  • Lesson task answer sheet
  • Homework task
  • Homework task answer sheet
  • Exmaple STL files to support the learning objectives

What teachers say ….

“The year 10 group who we are trailing it out with have made rapid progress and become much more confident and informed.” Ges Cocker, Dover Grammar School for Girls.

As with all of the lessons the files can be edited by the teacher allowing for maximum flexibility. This lesson will build on their parametric modelling skills and teach students about the different mechanical and behaviour properties of flexible filaments. It will allow them to get hands on with products that are printed in flexible materials.

The students will also learn how to design a small cable tidy for a phone charger. This can be 3D printed in around 20-30 minutes per student and uses up very little filament, meaning the lesson is cheap to deliver and easy to manage. During the lesson as well as CAD modelling tasks, there is a student theory worksheet for children to work through, along with a homework task.

This lesson will help students prepare for the design challenge lesson where they will have to demonstrate their parametric modelling skills responding to a series of tasks.
