The Fabricator is the central crafting station and base workbench. It is an Interior Facility placed inside a habitat using the Habitat Builder. All tools and most items in the game’s hundreds of item entries are crafted here.
You can build multiple Fabricators at different outposts, which matters in a large, mapless world — a forward Fabricator near a deep biome saves long return trips. In co-op, shared blueprints mean any party member can fabricate what anyone has unlocked.
