CAD to CAM in Tinkercad
Lesson details
Learning outcome
I can access, select and edit existing models and prepare them for 3D printing.
Key learning points
- Pre-existing CAD models can be accessed, copied, and edited in Tinkercad using the gallery.
- Designs can be modified by ungrouping, resizing, and combining parts to create more complex models.
- CAD models can be exported and prepared for manufacturing through CAM.
- Most 3D printers in schools use a process called fused filament fabrication (FFF).
- Once prepared, the model is sent to a CNC machine, such as a 3D printer, which builds the object layer by layer.
Keywords
CAD - computer-aided design
CAM - computer-aided manufacture
CNC - computer numerical control
Tinkercad - an online computer-aided design application
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 Tinkercad.
Licence

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.
