Project box

This advanced level lesson will take students through the process of designing an original product. Having been challenged to create a protective case for a Raspberry Pi 4, Arduino Uno, BBC Microbit or other microcomputer of your choice, and received a client brief, market research, and a product specification, students will be supported to produce a Product Design Specification (PDS). Students should detail their process from analyzing the information they have been provided with to producing a 3D printed final prototype design and presenting it to a client (you) for sign off. During the lesson, they will learn about prototyping techniques, the iterative design cycle, the importance of giving/receiving feedback and why modifying a design based on the client’s feedback is essential.

Objectives

  • Compile a PDS as specified in the lesson plan
  • Produce 3 initial prototype designs meeting the client brief and product specification
  • Complete at least one cycle of the iterative design process
  • Produce 1 final prototype design meeting the client brief, product specification and modifications required following the client and peer critical review
  • 3D model the final prototype design using a CAD program
  • 3D print the final prototype design
 

Tools and equipment

  • 1 x Raspberry Pi 4 / BBC Microbit / Arduino Uno or alternative suitable microcomputer
 

Skill requirements

This is an advanced level lesson aimed at senior students and requires a moderate level of technical knowledge and ability. You may adapt this lesson to suit junior students but please be aware that this will alter the curriculum alignment and lesson goals.

To participate in the lesson, students should be able to:
  • Have an intermediate understanding of Additive Manufacture (AM) and CAD
  • Be comfortable using technical language and producing simple technical drawings
  • Be comfortable producing simple technical drawings 
  • Use TinkerCAD, Fusion 360 or Similar CAD software at an intermediate level
  • Be comfortable using DeeControl2 software including adjusting print settings
  • Using the BE3D EDEE 3D printer
