Tell me (Memories of Mars)

Carbon fiber on pipes (wrapped around pipes, you will see it illuminated) in various small buildings and also from laser spiders. But I don't know gunpowder myself. I have already installed all the printers, I thought they were in them, I installed a laboratory and a blast furnace, but gunpowder is not being crafted anywhere and not even in the study.
