Dyson Sphere Program provides over 200 hours of content, but some players will initially get overwhelmed by the game’s complexity and quit. You may not know what to do after crafting your first Mining Machine. The optimal next step is to build a smelter. This guide will walk you through how to smelt ore automatically in Dyson Sphere Program. Crafting a smelter In Dyson Sphere Program, you can smelt ore manually in your Replicator. But if you want to speed up this process, you can build a smelter. To unlock the smelter, you must first research the Automatic Metallurgy technology in your Technologies menu.
