2 different blueprints that creates legendary Foundries.
First blueprint - Legendary Foundry Using (almost only) Common Items
This factory is not very fast as most of the items are common item, yet it's fast enough for most practical needs. If you simply needs legendary foundries, use this blueprint.
Notes:
- Some of the bulk Inserters must be legendary - do not change it
- Quality modules can be any, put your best modules up to epic.
- 50-100 logistics bots
Second blueprint - Late game factory with lots of legendary items
Who needs 10 legendary foundries / minute? No one, but it is simply too fun to not have it :) The second blueprint is fast legendary foundry factory. It is based on lots of legendary quality items.
- Self powered
- Overflow control included
Notes:
- All legendary Items are required
- Provide 250-400 bots (exact number depends on quality of bots and your current speed research)
- When you see several inputs to the same belt - it means that the items needs to be stacked in that belt
- DON'T CONNECT it to main logistics network as it will drain it
- DON'T CONNECT the solar panel to the main power network
Updates
14/Jan/2026 - Normal legendary foundry bp improvements:
- Switched to legendary Level 2 quality modules instead of epic Level 3 modules (easier to mass-produce)
- Added a proper stone disposal
- Simplified inputs:
- 1 lava input instead of two
- Changed input location + added balancers, so it can start working even when input is not at full capacity
- Changed all belts to green belts
- Flood control now activates only when the logistics network is actually flooded, so it won’t drain the whole network
8/March/2025 - Complete redesign of the late game blueprint - half the size, half the power, and faster
