I think an important thing to bring up is that the modern economy is fast on track to international integration. Violence or Earthquakes in China can have rippling effects throughout the international economy as many consumer goods at least raise in price due in part to disturbed supply. Violence in the middle east can raise oil prices across the world. So somewhere there had to be advancement that reconditions societies for some economic independence, or the belligerent sides somehow break down in alliances that somehow give all sides enough of a share of resources they only need to worry about how to ration it.

But one thing's for sure when we're done, the international market and the face would most likely shift as post-war sanctions take effect, or during-war sanctions on other nations continue stubbornly.

This will in turn not only re-shape the face of government in the military and its functions, but the public conscious as they argue if the "old way" is better or if they should pursue a "new way". 3D printing could very well become a thing modern socialists cling to, parading it as the means for public production all throughout society as the traditional capitalist elements seek to control it to protect their self interests.

You could also have situations where the ASF itself can find it very, very easy to arm itself with custom parts and become a majority independent of the world market through 3d printing, which could be a part of growing manufacturing independence, which adds to economic independence all over. Why have china build your cars when you can print and assemble the parts in the garage? Or why let the common man do it when traditional bourgiese bodies can clamp down on public use and use 3d printing for cheap at-home production?
