New 3D printing slicing methods like "Brick Layers" are adding up to 30% tensile strength and significantly increasing waterproofness. The age of 3D printing is upon us and it will be massively disruptive (repo below)

.@StephenABoydPh1 and I postulate the first Martians will use ISL (in situ leaching) to pull salty brine, Thorium and uranium from icy bedrock. This will provide energy and a valuable source of water with a high earth TRL. Do you want to see an article on this?
