Bloodhound Education have kindly shared the STL 3D model files for a complete Bloodhound car model. The model has been created from original Bloodhound Car CAD files and is in modular form consisting of five parts that can be printed separately and assembled together.
The model provides a interesting hook for introducing the 3D printing processes but also for extended STEM and Science activities, for example:
- Students can design their own wheels for the model to learn basic 3D modelling skills, then when these have been sliced and 3D printed they can test them on the car and explore how different variables such as the size and thickness and internal geometry of the wheels affect the distance the car will travel when released down a ramp.
- Investigate friction by covering the ramp with different surface materials.
- Investigate Forces and the relationship between mass and acceleration (F=ma) by 3D printing two identical models with different infill percentages to produce models with different masses that can be tested against each other.
To print the complete model at 100% will require two separate prints to be run. The screenshots below, show the best orientation for setting up and slicing the model parts ready for 3D printing. Supports will be required in order to print the parts. If you are scaling the model down, it may be possible to fit all the parts onto a single print bed.
The CREATE Education Project would like to thank Bloodhound Education for sharing this resource.
