Advanced Smelting Upgrade

Efficiency Modules

Advanced Upgrade that greatly increases efficiency when crafting Advanced Smelting recipes.

Notes

The Advanced Smelting Upgrade is an Efficiency Module that reduces the resource cost and craft time of Advanced Smelting recipes when installed in a compatible crafting station. It belongs to the "Advanced" tier of upgrades, meaning it requires the station to be inside a room of sufficient quality (tier-2 or higher) to function. For efficient mid-to-late game metal processing, prioritize installing this module on your furnaces or smelters—each upgrade level contributes up to roughly 5% efficiency improvement, capped at about 25% total.
