manufacturing Building Comparison
Component Factory vs Stellar Forge
Comparing the Component Factory and Stellar Forge, both manufacturing buildings in Starforge MMO. Base plots and energy upkeep are scarce, so use this to decide which structure earns its slot first.
Build & Output Comparison
| Attribute | Component Factory | Stellar Forge |
|---|---|---|
| Max level | 15 | 5 |
| Base cost | 1,800 metal, 1,200 crystal, 400 gas | 30,000 metal, 20,000 crystal, 1,000 antimatter, 5,000 gas |
| Upkeep | 35 energy, 25 metal, 10 gas | 300 energy, 15 antimatter, 100 metal |
| component output per hour / level | +8★ | — |
| module craft cost reduction / level | +0.02★ | — |
| tier5 module craft slots / level | — | +1★ |
| legendary craft quality bonus / level | — | +0.05★ |
★ marks the higher per-level output. Compare against your base's current bottleneck before committing a plot.
Component Factory
Produces intermediate components — alloys, chips, and power cores — used in advanced ship construction and module crafting. Higher levels increase output volume and unlock additional component types.
Requires tech: advanced manufacturing i
Requires building: shipyard
Stellar Forge
A titanic manufacturing facility powered by directed stellar plasma that achieves the temperatures required to craft tier 5 modules — the highest-tier equipment available. The only structure capable of working with antimatter at the precision required for legendary-grade fabrication.
Requires tech: stellar metallurgy
Requires building: module factory
Which Should You Build First?
Both are manufacturing buildings, so the choice depends on your current bottleneck. Prioritise the structure whose highlighted per-level output addresses your scarcest resource, and weigh that against its energy upkeep — a high output that drains your power grid can stall the rest of your base.
