Zero-Gravity Cup and Bowl – A Prototyping Project
This second year project challenged us to try out as many different prototyping methods as possible within the space of one nine week module. The brief was to design a better way for astronauts to eat on the International Space Station.
The prototyping methods that I chose to explore were:
- Oil Clay Modelling
- CAD Modelling on Solidworks
- FDM PLA 3D Printing
- SLS Ceramic 3D Printing
- Laser Cutting
- Vacuum Forming
- 2 Part Plaster Mould Making
- Silicone Casting
- Oil Sand Mould Aluminium Casting
- Lathe Turning
My two final pieces were a zero-gravity cup and bowl set.
The zero-gravity cup was based on the form of astronaut Don Petit’s plastic sachet which holds fluid in a zero-gravity environment through surface tension. Through prototyping with oil clay I developed this into a more ergonomic and beautiful form. The final piece was cast in aluminium using a two-part oil sand mould.
The zero-gravity bowl was shaped using Solidworks and 3D printed in ceramic. The concept is that the texture on the surface of the bowl would hold food through surface tension and the halogen bulb mounted to the lid would heat the food.
Together, the cup and bowl create a more pleasant and familiar eating experience for the astronauts.
This booklet details the design process behind the project. To read in depth details, my blog posts about the process can be found here.
