Fasteners - screws, bolts, washers, brackets, conduit, nuts, wire - both coated and uncoated
There are many sources of how we will mine the regolith for ores that contain useful quantities of water, iron, aluminum, titanium.
There are also great sources on 3d printing of parts.
My question is for the bulk creation of these fundamental parts of construction, has anyone done an analysis or a paper on the likely processes employed to be sure our martians are well supplied with screws?
I tried to give a small amount of comedy with that last statement, but I am absolutely serious. I am interested in getting past the "magazine cover" issues and get down to the nuts and bolts of colonizing Mars.
And I thought to start with getting this nailed down.
While 3D printing is amazing, I would think we would actually want to re-create many parts of the current industrial practices of milling and shaping metallic parts. Reading about making wire it is a surprisingly sophisticated process and I cannot see us wasting BFR trips with buckets of bolts from Home Depot.
So, any pointers on the first or second order solutions here?
