EVE Online Manufacturing Guide: Blueprints, ME/TE, and Real Margins

Blueprints: originals, copies, and runs

Everything manufactured in EVE starts with a blueprint. A Blueprint Original (BPO) never expires: it can run manufacturing jobs forever, be researched to improve its efficiency, and produce Blueprint Copies. A Blueprint Copy (BPC) carries a limited number of runs and cannot be researched further — but copies are how blueprints are traded safely, and they are the required input for Tech II invention.

Tech I BPOs are sold on the market by NPC corporations, so their supply is unlimited — which is worth remembering when someone offers you a "rare" T1 original on contract. BPCs change hands through contracts, and a researched BPO's value is mostly the research time somebody already sank into it.

ME and TE: what research is actually worth

Material Efficiency (ME) research reduces the materials a blueprint consumes per run, up to a maximum of 10% at ME 10. Time Efficiency (TE) research reduces job duration, up to 20% at TE 20. Each research level takes longer than the last — small T1 blueprints reach full research in days, while large hulls can take months.

• ME is money: on high-volume production, the difference between ME 0 and ME 10 is roughly the difference between breaking even and profiting. Research ME first, always.
• TE is throughput: it matters most when your production slots are the bottleneck or you are racing a market window.
• For anything you plan to build repeatedly, research before you produce. Competing against ME 10 industrialists with an unresearched blueprint means their cost floor is simply below yours.
• If you cannot wait out the research time, buying well-researched BPCs on contract is often cheaper than the ISK you would lose building at ME 0.

Job costs and the system cost index

Installing any industry job charges a fee based on the estimated value of what you are building, multiplied by the system cost index — a number that rises with how much industry activity is happening in that solar system. Busy hub-adjacent systems are expensive to build in precisely because everyone builds there; a few jumps into a quiet backwater, the same job can cost a fraction as much. Facility taxes and surcharges stack on top.

Where you build matters as much as what: player-owned engineering structures grant material and time bonuses over NPC stations, and rigged structures push those bonuses further. Serious producers weigh structure bonuses, system cost index, and hauling distance together — the cheapest system on paper is not cheaper if moving materials there eats the savings.

What to build — and the "free minerals" trap

The most common industry mistake in EVE is believing minerals you mined yourself are free, so anything you build with them is profit. They are not free: every mineral you consume could have been sold at market price. If your finished item sells for less than its input materials plus fees, you are converting valuable minerals into a less valuable product and calling the destruction "profit". Always price inputs at what they would sell for.

• Commodity T1 hulls and modules have brutal competition — everyone owns the same BPO — so margins are thin and go negative regularly. Verify before every batch; never assume last month's margin survived.
• Demand concentrates around conflict: doctrine ships, ammunition, and fitting modules sell steadily near staging areas, and local sellers charge a convenience premium over Jita.
• Niche items with steady-but-small demand often out-margin famous ones because fewer industrialists bother to compete there.
• Ammunition, drones, and other consumables are the index funds of industry: low margin, endless volume, and demand that war only increases.

Tech II and invention, briefly

Tech II production is where most full-time industrialists end up, because extra steps keep casual competition out and margins in. The pipeline: copy a T1 blueprint, run invention on the copy using datacores (with optional decryptors to tune the odds and output), and succeed some percentage of the time at producing a T2 BPC. Science skills raise your success chance. The T2 build itself then consumes advanced components derived from moon materials, adding a second supply chain.

Do not start here. Run researched T1 production until pricing chains and job logistics feel routine, then add invention one product at a time. The industrialists who profit from T2 are the ones who know their exact cost per successful copy — chance included — before committing.

A workflow that protects your margin

1. Price the full chain first: materials at market value, job fees at your system's cost index, structure bonuses, and sales fees on the way out.
2. Confirm the sell-side volume. A fat margin on an item that sells twice a week is inventory, not income.
3. Research or source ME before committing to volume production.
4. Batch production to fit your real login schedule, and keep jobs running overnight — idle slots are the silent cost.
5. Re-check margins every batch. Mineral prices and competition move constantly, and industry rewards the person who notices first.

The arithmetic is not hard, but doing it by hand for every product is how people stop doing it. The EVE-HUB Industry tool calculates build profitability with ME/TE and taxes factored in, tracks your blueprints, and monitors running jobs — and pairs naturally with the Watchlist for watching your input and output prices across hubs.
