This thesis investigated the way in which microgravity can affect the solidification process of metals. An understanding of this process is essential to improve the structures of metals and to support the merit of manufacturing in space. Materials that are processed in a microgravity environment can often exhibit unique properties such as an increase in ductility or stronger thermal properties.

The main objective of this thesis was to outline a design of a drop package to be tested in the UQ drop tower. Other microgravity facilities were also explored to ensure the best conditions for testing.

Testing in the UQ drop tower provided only 2s of microgravity. Thus it was challenging to design a drop package which would allow the metal to solidify in that short timeframe. Using Matlab, I was able to determine the necessary dimensions (30cm Length x 10 cm Height) of the design in order for solidification to occur. This design is able to test an aluminium sample of 5cm radius. Hopefully after future testing is conducted, We will be able to improve the quality of material processing and therefore enhance the properties of metals.
