CAM: communal areas
Lesson details
Learning outcome
I can prepare and manufacture a 3D model using computer-aided manufacturing.
Key learning points
- 3D printing is also known as additive manufacturing process.
- Most 3D printers in schools use a process called fused filament fabrication (FFF).
- 3D models need to be prepared for printing using a slicing application.
- 3D printing allows manufacturers to change the design quickly and easily.
- There are basic design for manufacture rules to follow when producing models for 3D printing.
Keywords
Filament - thermopolymer material used by 3D printers to create objects
FFF - fused filament fabrication
DFM - design for manufacture
Common misconception
Any model can be 3D printed using fused filament fabrication 3D printing.
Design for manufacture rules need to be considered when 3D printing. Not all models are suitable.
Teacher tip
3D print a set of the reference models found in the lesson to give pupils a better understanding of the limitations of FFF 3D printing.
Equipment
Computers/laptops, mice, access to a 3D CAD applicaiton and slicing software. Access to a 3D printer.

We use learning cycles to break down learning into key concepts or ideas linked to the learning outcome. Each learning cycle features explanations with checks for understanding and practice tasks with feedback. All of this is found in our slide decks, ready for you to download and edit. The practice tasks are also available as printable worksheets and some lessons have additional materials with extra material you might need for teaching the lesson.
The assessment exit quiz will test your pupils' understanding of the key learning points.
Our video is a tool for planning, showing how other teachers might teach the lesson, offering helpful tips, modelled explanations and inspiration for your own delivery in the classroom. Plus, you can set it as homework or revision for pupils and keep their learning on track by sharing an online pupil version of this lesson.
