Smelting Upgrade

Efficiency Modules

Advanced Upgrade that greatly increases efficiency when crafting Smelting recipes.

Notes

The Smelting Upgrade is an advanced Efficiency Module that significantly reduces resource consumption and craft time for Smelting recipes when placed in a compatible crafting station's module slot. It fits into the upgrade progression after basic modules, with its effectiveness capped at around 25% total reduction alongside other upgrades (as of Update 13). If you run a furnace or smelter, installing a Smelting Upgrade lowers the material and labor cost per batch, making it a worthwhile investment for any dedicated metalworker or refinery operator.
