Speed module 3 — Factorio Production Calculator
Speed module 3 is crafted in the assembling machine in 60 seconds, producing 1 per craft from 4 × Speed module 2, 5 × Advanced circuit, 5 × Processing unit. At 60 per minute you need 120 assembling machines, and the chain behind it draws on 5 raw resources: petroleum gas, copper ore, iron ore, water, coal.

Raw materials
| Resource | Per minute |
|---|---|
| Petroleum gas | 197,250 |
| Copper ore | 98,700 |
| Iron ore | 53,550 |
| Water | 26,250 |
| Coal | 9,300 |
Machine counts are not rounded up. Add a little headroom in game — belt throughput and inserter speed usually mean you want 5-10% more than the exact number.
Speed module 3 recipe
| Machine | Crafting time | Output | Ingredients |

| Assembling machine | 60 s | 1 | Speed module 2 × 4, Advanced circuit × 5, Processing unit × 5 |
What the whole chain needs
60 speed module 3s per minute pulls in 11 intermediate products, and the whole tree comes to 14,019 machines across 3 machine types, fed by 5 raw resources. The table above already sums demand across every branch — if copper cable is used by two recipes, you see the total, not one of them.
Belt check: the busiest input here moves 197,250 per minute, which is 219.17 of a yellow belt's 900 per minute. Above 1.0 and you need a second belt (or a faster tier) before the machines themselves become the limit.
What uses speed module 3
No base-game recipe consumes speed module 3 — it is an end product. Once you build it, the chain stops here, which makes it a good target if you only want to size the sub-factory that feeds your mall.
What speed module 3 is made from
- Speed module 2 — 4 per craft
- Advanced circuit — 5 per craft
- Processing unit — 5 per craft
FAQ
How many assembling machines do I need for 60 speed module 3s per minute?
120 assembling machines. One at standard speed produces 0.5 per minute, so 60 ÷ that number is the count. The calculator above rounds nothing — add 5-10% headroom for belt and inserter losses in a real factory.
How much raw ore does speed module 3 take?
At 60/min the chain consumes 197,250 petroleum gas per minute, 98,700 copper ore per minute, 53,550 iron ore per minute and 2 more. Those numbers are the theoretical minimum — mining productivity research and productivity modules both reduce them.
