Marscraft Keystone Silicone Sandfilled Sacs

thingiverse

3d Printed silicone ( similar material that maintains shape) sacs that would be filled with sand in Mars to create buildng blocks. Part of the building would be dug into the earth as chambers (Trenches) of different sizes. A reusable printed structure would be used to build the Arcs with the Keystones and then repeated until the desired length is attained. Communication between Chambers can be done via tunnel or a slim Trench depending on the distance. A 3d printed thin tube ( or sheet that can be sealed ) would be used to cover the inside of the chambers that would need to ( long passage trenches or warehouse trenches might not need it. This efficient method can be used to cover long areas of development that can contain the greenhouse, water treatment plant and even to cover the arriving spacepods Martians will like this design as the arriving pods will be small and limited, and with this technique they can even build a movie theater just steps away from their ships ( ships that can also be covered and protected by these means) This is inspired by sandbags that we used on a city that was being flooded by a huge river. Seeing how a simple sandbag wall lined with a plastic sheet between them could contain a river was amazing. And also the enormous Stone Bridges that have survived until our modern times.
