Utility science pack — Factorio Production Calculator
Utility science pack is crafted in the assembling machine in 21 seconds, producing 3 per craft from 3 × Low density structure, 2 × Processing unit, 1 × Flying robot frame. At 60 per minute you need 14 assembling machines, and the chain behind it draws on 6 raw resources: petroleum gas, water, copper ore, iron ore, heavy oil, coal.

Raw materials
| Resource | Per minute |
|---|---|
| Petroleum gas | 6,100 |
| Water | 3,500 |
| Copper ore | 2,990 |
| Iron ore | 2,000 |
| Heavy oil | 300 |
| Coal | 230 |
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.

| Assembling machine | 21 s | 3 | Low density structure × 3, Processing unit × 2, Flying robot frame × 1 |
What the whole chain needs
60 utility science packs per minute pulls in 18 intermediate products, and the whole tree comes to 465 machines across 3 machine types, fed by 6 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 6,100 per minute, which is 6.78 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 utility science pack
No base-game recipe consumes utility science pack — 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 utility science pack is made from
- Low density structure — 3 per craft
- Processing unit — 2 per craft
- Flying robot frame — 1 per craft
FAQ
How many assembling machines do I need for 60 utility science packs per minute?
14 assembling machines. One at standard speed produces 4.3 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 utility science pack take?
At 60/min the chain consumes 6,100 petroleum gas per minute, 3,500 water per minute, 2,990 copper ore per minute and 3 more. Those numbers are the theoretical minimum — mining productivity research and productivity modules both reduce them.
