Each lesson is designed to last approximately one hour. All worksheets and homework sheets come with answer sheets so students can self assess or peer assess their work, reducing teacher workload and involving the students fully in assessment for learning. All worksheets, homeworks, tutorials and STL files as part of the expert curriculum are downloadable.
In lesson 25, 26 and 27 there are 12 Fusion 360 tutorials that teach learners how to design jewellery for resin 3D printing. The tasks that learners have to complete have been designed to be small and quick to 3D print out of resin. This helps keep the costs of projects down and also allows for multiple models to be printed off at once.
The final assessment is split into two sections. Section one is a practical assessment using Fusion 360 where learners have to complete a series of quick modelling tasks and then analyse them to find out the mass/density/area. If they have modelled the tasks to scale they will be able to recognise the correct answer (all questions are multi choice). The second part of the assessment tests students on the learning of the theory element of 3D printing.
This lesson pack compliments the Advanced 3D printing lesson pack and it can be used to introduce students to resin 3D printing as a follow on from the Advanced pack. Alternatively, it can be used as a stand-alone series of lessons with students who have not experienced any 3D printing before. It is recommended that students have experience of CAD before teaching this lesson pack.
Lesson resources include;
- Read through lesson plans for each lesson
- Lesson powerpoint presentations to cover each lesson/tutorial
- Homework tasks with answer sheets
- Video tutorials for all 12 modelling tasks
- Links to case studies
- 1 Final assessment powerpoint with answers
- Examples STL files to 3D print

- Discuss the environmental impact of using thermoset resins during resin 3D printing.
- Discuss the environmental impact of using thermoplastics during filament-based 3D printing.
- Recognise the difference in outcomes from DLP printers and SLA printers.
- Explain why models need to be post processed.
