Overview and Background
Create a 3D printed spaceship with basic wiring, switch, batteries and LED's
This small project will inspire students to;
- Print a complex model with a high degree of success (supports etc.. provided)
- Allow them to wire and assemble a basic circuit
- Require relatively fine soldering skills
- Work out a step-by-step means of assembly
Lesson Plan and Activity
3D printer and software (Repetier, Simplify3D, Slic3r etc..)
- Introduction - Bringing virtual reaility into reality (Inspire with NMS video)
- Navigate to this model in Thingiverse and download to computer. Final model should look like attached STL file.
- Highlight supports and layout of model (why are supports required? etc..)
- Ideally printed in PLA (explain filament differences etc..)
- Layout models in 3D software, set printer settings etc..
- Print model
Lesson 2 & 3
- Hand out printed models
- Careful removal of supports and parts (hood, landing gear and stand)
- Tidying up of model - cleaning rough edges, making sure parts fit etc..
- Paint if necessary using acrylic paints and fixers
- Prep for next lesson - lighting it up!
Lesson 4 & 5
- Overview of basic circuit diagram and components (example finished model)
- Work out what needs assembly first, soldering and other considerations (e.g. extra length of wire etc..)
- Soldering of LED's and switches, battery tabs etc..
- Testing and appraisal
- PLA filament (white 1.75mm)
- Acrylic paints and fixers
- 2x 2.5mm white LEDs
- 1x 5mm blue/white LED
- 1x 8x8x13mm DPDT push switch
- 2x LR44 1.5V batteries
- 2 colour wire reels (red/black)
- Soldering iron, solder
- 3D printing
- Basic electronics
- 3D printer setup
5 hours (excluding print times)
