【Factorio】Research Priority and Early-Game Route (Beginner's Guide)

Right after the tutorial, red science flows smoothly—but as you keep hand-crafting belts and inserters, research grinds to a halt. In Factorio, this is where most players hit their first wall. This guide walks beginners through vanilla 2.0 early-game research, offering a time-tested approach: prioritize research that eliminates manual work and logistics bottlenecks before chasing powerful upgrades.

My strategy is straightforward: start by automating red science, move into green science automation, stabilize power, then scale steel and circuit board production. Using the official belt capacities—yellow 15 items/sec, red 30/sec, blue 45/sec—I'll explain where factories typically jam and walk through three early-game route variations. Space Age shifts the tech tree significantly, so I'll touch on those differences separately; but the foundational principles remain the same. Before flooding the labs with science packs, transfer the tasks you're doing by hand to machines—that's the design philosophy that makes early-game expansion smooth.

How to Think About Early-Game Research Priority: Start with Automation Research

When planning your early research order, I focus on "what research cuts out bottlenecks?" rather than "what research unlocks something powerful?" As explained in the official Research article, labs consume science packs and maintain progress even after you switch topics. Nothing is wasted, so you can pivot research toward whatever's causing the most friction.

The key is not getting distracted by the research tree's visual appeal. Early-game research speed gains matter little if iron plates and copper plates are clogged—the flow upstream is still broken. I initially wanted to boost research speed, but discovered that belts were jamming and materials weren't reaching the lab anyway. Research's real value comes from the whole pipeline: mining, smelting, transport, and assembly. Faster labs don't help if the copper can't get there.

Decision Framework

Focus on three pillars: manual labor reduction (automation), transport efficiency (logistics), and power stability (generation/distribution). First priority: get machines doing what your hands have been doing. Assembling machine 1 has 0.5 crafting speed, so a 1-second recipe takes 2 real seconds. That's slow, but it runs 24/7 while you handle other tasks. The sooner you switch from hand-crafting to machine production, the sooner you unlock growth.

Second: examine logistics. Yellow belts carry 15 items/sec; red carry 30; blue carry 45. A 2x jump from yellow to red is dramatic. Early-game feels fine with yellow, but once iron plates, copper plates, gears, and circuits all compete on one lane, yellow saturates fast. Copper especially gets underestimated—it disappears into circuits and research—so watch material flow carefully.

Power is just as critical. Adding labs without sufficient generation leaves the whole factory limping. One boiler supports two steam engines at 900 kW each—so one boiler + two engines = 1.8 MW theoretical output. Power shortages mask themselves as slow research, sluggish inserters, and disappointing throughput. Treat power expansion as urgent as research priority itself.

This mindset aligns with the official Tutorial:Quick start guide. Red → green automation, then widening the factory base beats grabbing one powerful tech. The right research order isn't a fixed formula; it's whatever removes your current bottleneck fastest. Think in terms of flow, not headlines.

Target Version and Goals

This guide centers on Vanilla 2.0. I'm covering red/green science automation, logistics setup, steam power stability, and steel/circuit scaling. I'm deliberately keeping Space Age separate to avoid confusion.

Space Age (released October 21, 2024) is paid DLC with new planets, space platforms, and a restructured tech tree. The rocket silo's role changes—it's no longer an end-game goal but a mid-game checkpoint. However, the early fundamentals don't shift: automation, logistics, and power must come first, or nothing that follows will work. I'll address Space Age differences at the end; for now, the goal is solidifying vanilla 2.0 early-game judgment.

This section isn't a rigid table. Official sources confirm research mechanics and belt speeds; building practical priority from there is the real skill. You need "research that keeps production flowing," not "the flashiest research." Internalize that, and the rest clicks into place.

Foundation: Resources and Equipment to Stabilize First

Fuel-Mining Setup and Stone Furnaces

Before optimizing research, lock down coal. Iron and copper ore are visible—but without coal, fuel-mining drills and stone furnaces grind to a halt. Coal isn't just material; it's the engine starter. My early factories often stall because coal supply thinned. Mining and smelting both need it.

Build a reliable iron plates, copper plates, and stone supply using fuel-mining drills and stone furnaces. The official Tutorial:Quick start guide emphasizes this foundation. Fuel drills are your first mining option, and stone furnaces smelt ores with coal. Research follows on top of this—if the base is weak, research suffers immediately.

Lay out coal extraction on a coal patch using a fuel mining drill, then route that coal to iron ore smelting and copper ore smelting. Grab stone early too; it prevents stone furnace and wall construction from bottlenecking. You won't burn through stone quickly yet, but having it available beats constant shortages mid-expansion.

Crucially: separate iron and copper smelting into different rows from the start. Early-game feels fine with a few furnaces, but Factorio saturates fast. Later you'll want to stack more furnaces vertically and horizontally. Leave 2-3x expansion room so you don't rebuild constantly. Close layouts invite chain teardowns when you hit bottlenecks.

Minimal Red Science Supply Line

Once resources stabilize, feed the labs with a barebones semi-automated red science line. Don't target full automation immediately. Science packs preserve progress, and you can switch research anytime. Stability beats perfection. One or two labs is plenty early-game; a continuous trickle of packs matters more than research speed.

My recommendation: assemble red science packs, hand-resupply one ingredient, let the output flow to labs uninterrupted. This requires few parts and doesn't strain iron heavily. Automation science pack production is detailed— the recipe time isn't always 5 seconds. One assembler can't supply huge volumes, so early-game prioritizes "never stop" over "maximize speed." One or two labs feeding steadily trumps four labs that hiccup.

Early-game's most-overlooked resource is copper plate allocation. Iron gets attention (belts, gears, obvious demand), but copper flies under the radar. Plenty remains until circuits hit, then it evaporates. Copper scales deceptively fast.

Position the red science line off to the side with room to add green science and intermediates later. If you cram it centrally, you'll lose space for belts, inserters, and circuits when you need them. A single belt in front of the lab and extra space to expand the supply assembler buys huge flexibility.

Don't Underestimate Copper Distribution

Early-game's most-overlooked resource is copper plate allocation. Iron gets attention (belts, gears, obvious demand), but copper flies under the radar. Plenty remains until circuits hit, then it evaporates. The Copper plate wiki page warns exactly this: copper scales deceptively fast.

I see it every run: I expand gears (iron-heavy), feel iron-starved, so I add iron furnaces. Then I layer on green circuits, and suddenly copper vanishes. Iron shortage feels obvious; copper starvation creeps up. Early split allocations favor iron by default, then circuits collapse from copper depletion.

Split iron and copper smelting from the start, and give the copper row its own expansion buffer. Circuits are a universal dependency—research, logistics, manufacturing. Copper shortages radiate across the factory. Plan accordingly.

Stone completes the trio: stone furnaces consume it, and later stone bricks become critical. Establish stone supply early. Pair stone + coal + iron + copper as your baseline, and research gains traction naturally.

Recommended Research Priority | Red-to-Green Science Core Route

Standard Route

To smoothly transition red to green science, follow this axis: automation → logistics → lab upgrades → power → steel → green science launch. This mirrors the official beginner flow. Belt and inserter hand-crafting disappear first, then transport and power solidify, then you escalate production. Fewer bottlenecks overall.

First: automation research for Assembling machine 1 and inserters. Assembling machine 1 has 0.5 speed—1-second recipes take 2 real-time seconds. Slow, yes, but it frees you from hand-crafting belts, gears, and science. Any one production line becoming automatic cascades: the next research prep gets lighter, materials flow better.

Next: logistics research—belts, splitters, underground belts. Yellow belt capacity (15 items/sec) works early-game. What matters more is splitter 1:1 distribution and underground belts dodging intersections. Basic underground belts span 4 tiles underground; that alone untangles furnace rows, research lines, and parts lines. Skipping this cramped factories fast. Experience shows rebuilds cost way more than early logistics investment.

Research infrastructure comes next, but not more labs—continuity matters. Labs scale by count but drain packs quickly. Running a few labs on steady supply beats stuffed labs that starve. One or two working labs advance faster than six hungry ones. Emphasize supply reliability, not speed.

Once production runs smoothly, add one power tier. Assembling machines, inserters, and labs consume way more power than you expect. One boiler + two steam engines should run routinely; expand in lockstep with demand. If power dips, inserters slow, research pauses. Voltage problems feel invisible until everything lags.

Then steel unlocks, prepping for green science. Steel costs 5 iron plates per plate—a heavy demand. Research that now, when iron and power have cushion. Steel-using upgrades transform the factory from "temporary setup" to "expansion-ready base."

After green science goes live, pump intermediate upgrades before chasing new colors. Circuits appear everywhere—circuits limit everything. Early green typically chokes on circuits, copper, or inserters. Before advancing, shore up these bottlenecks. Circuits early-game spreads thinly; boost circuit supply, and the whole pipeline relaxes.

Stability-First Route

If your factory stalls on blackouts and material shortages rather than enemy pressure, push power and intermediates earlier than standard. Automate the same early cascade, but insert power and circuit buffers before expanding labs. Research crawls slightly, but factory uptime soars. Real playtime often favors uptime.

Boost power infrastructure and generation capacity ahead of research acceleration. Running red + green packs on multiple labs drinks enormous power. When generation falters, inserters lose rhythm, assemblers choke, research halts. Upgrading labs without power is hollow. Stability-first bumps power up, so the factory breathes easier when stepping up production.

Jump on circuit supply early. Green science, belts, inserters, assemblers, and labs all crave circuits. Copper starves fast once circuits roll. Pre-emptively widen the circuit line—copper furnaces, copper wire production, circuit assembly—before green science comes online. Smooth progression beats mid-crisis expansion.

Logistics early helps too: splitters and underground belts unlock immediately. Route resources cleanly: research, parts, smelter feeding. Underground belts clear congestion. A tidy, spacious layout survives additions without collapse.

Military-First Route

On high-threat maps—nests close, pollution spreads fast, biters are already raiding—fast-track turrets and ammo. Grab early automation, then pivot to defense before pushing green aggressively. The logic: a destroyed factory teaches no lessons; alive factories beat dead ones.

Unlock turrets and ammo research while red science runs. Time-buy with defense, shore up automation/logistics/power/steel on the back. By the time core production stabilizes, turrets feed steady ammo, and raids diminish. Return to standard routes once breathing room exists.

Defense demands power too. Turrets, ammo production, and supply inserters all draw juice. Defend-first means extra power infrastructure. Blackouts break ammo supply chains, defeating the exercise.

Expansion-First Route

Low enemy pressure but want a scalable early-game footprint? Push logistics aggressively. Automate red, then heavy logistics before boosting labs. Minimal research labs, power follows demand, early steel ties it together, then green science unlocks full intermediate research.

Core idea: squash spaghetti early. Yellow belt (15 items/sec) carries enough volume but stumbles on routing. Splitters split resources cleanly; underground belts cross cleanly. No splitters? Tap-offs build up, merging becomes messy. Underground belt skipped? Ground-level crossing chains compound. Each expansion multiplies friction. Expansion-first pays logistics friction in research upfront, reclaiming speed via clean geometry.

Steel unlocks earlier too. Steel recipes consume 5 iron per plate—heavy. But expansion-first sees value: iron-hungry upgrades (electric furnace, higher-tier assemblers) run on steel tech. Unlock steel early, teeth it, iron supply climbs to match—all before mid-game pressure spike.

Green science → chase immediate foundational upgrades, not colors. Circuits, inserters, belts. Skip shiny mid-tier research; shore up the base. A wide, clean, supply-heavy factory scales better than a tall, narrow, supply-starved one. Expand-first captures this by locking down geometry early.

Why Each Research Belongs Early: Factory-Centric Reasoning

Automation

Automation unlocks early because it converts hand-work into factory work. Assembling machine 1 and inserters let you stop hand-crafting recurring items: belts, gears, science packs. A slow 0.5-speed machine running forever beats you hand-crafting intermittently. The switch frees your attention for expanding, and continuous production stabilizes supply.

Moreover, research speed depends on stable science supply. Labs multiply research rate if packs keep arriving. Bottleneck is upstream: automating red science is the prerequisite to scaling research labs. Your first auto-production line becomes the template for everything after.

Logistics

Logistics research accelerates early because transport architecture solves cascading jams. Yellow belt (15 items/sec) seems sufficient until gears, circuits, and red science all crowd one lane. Splitting load, distributing fairly, and crossing intersections via underground belts untangles the whole layout.

The math is stark: 15 items/sec divided among three demands starves all three. Splitters divide; underground belts dodge. Result: flow resumes. Skipping logistics breeds spaghetti; rebuilds cost more than early logistics.

Power / Distribution Priority

Power weakness masks itself as slowness, not failure. Ore shortage looks visible; power drought feels like lag. Everything slows slightly, research drags, belts move sluggishly. The cause hides.

Early steam power (1 boiler + 2 steam engines) yields 1.8 MW theoretical. Small, scalable units. Pre-emptively expand power in step with demand growth. Research labs, assemblers, mining rigs, inserters all leap online together—demand jumps hard. Power prepared in advance irons out stops. Power deferred breeds invisible chokepoints.

Pylons matter too. Tight distribution forces rebuilds when expanding. Clean pole routes cost more upfront but scale smoothly. Factory speed depends on power continuity, not just raw generation.

Steel (Iron Plate → Steel Plate)

Steel costs heavy: 5 iron plates → 1 steel plate. Unlocking steel means accepting that iron demand doubles at the furnace. Why unlock it early, then? Because unlocking it reorganizes your smelting for the future.

Steel users appear mid-game (turrets, upgrades, advanced assemblers, walls). Requiring steel is a "foundation transformation" signal. Your factory shifts from "running the present" to "preparing to scale." Delaying steel means every mid-game expansion hits a "add more iron" loop. Pre-emptively boosting iron capacity (via steel unlock) shortens those delays.

Military / Turret Research Timing

Military research timing hinges on pollution reach and biters. Don't always prioritize it; instead, reserve a research slot for when enemies threaten. Pollution spreads with production. Defense isn't preemption; it's operational continuity under pressure.

When bites start, ammo supply chains matter as much as turrets themselves. Splitters route ammo priority; underground belts carry supplies across the perimeter. Clean supply chains make defenses work. Splitters and underground belts from logistics research again prove their worth.

Overcommit to military, and intermediate bottlenecks strangle expansion. Balance matters: logistics + military + production upkeep.

Circuit Line Optimization

Green science often bottlenecks on circuits. Circuits feed into inserters, research, higher-tier assemblers, everywhere. When multiple goals choke simultaneously, circuits frequently underpin the issue.

Strengthen circuits by isolating the line: copper plates → copper wire → circuits in a straight path, separate from iron demands. Inserter geometry matters—orient them for minimum transit. A linear circuit line outproduces a tangled one. Later, circuit demand only grows, so a solid line built early sustains expansion.

Circuit strength is really future-proofing. Clean copper → wire → circuit flow becomes the backbone. Build it right, and mid-game research additions don't derail it.

Early-Game Timeline | Red Science Automation Through Green Science Launch

30-Minute Mark: Red Science Automation and Power Ramp

Target: separate red science from hand-work and establish continuous lab feeding. Automating the supply keeps research rolling; hand-crafting interrupts it constantly.

Path: bulk up mining/smelting first, overlay red science production, push toward full auto. Don't aim for perfection—semi-auto (with one hand-supplied ingredient) works. But orient it so adding a belt converts it to full auto later. Bad semi-auto layouts force teardowns.

Research labs stay minimal. Feed them with a stable trickle, not speed. Small flows beat large starvation. Simultaneously establish steam power generation: boiler 1 + steam engine 2 is the minimum, 1.8 MW theoretical. Expand in lockstep with demand.

Power growth ties to automation growth. More labs, more assemblers, more mining rigs, all mean more power draw. Anticipate demand; the power screen graph shouldn't dip.

60-Minute Mark: Logistics Overhaul and Green Science Prep

Assumption: red science feeds labs smoothly.

Focus: untangle transport with splitters and underground belts. Yellow belts (15 items/sec) seem fine until you overload them. Splitters distribute fairly; underground dodge intersections. Move smelting and parts off the main axis slightly, leaving room for research and supplementary lines.

Identify bottleneck type: is production slow due to iron shortage or copper shortage? Symptoms differ. Iron scarcity halts belts, inserters, gears and steels. Copper scarcity chokes circuits, which in turn strangle inserters, research, and higher-tier assemblers. Treat them separately.

Iron-short? Boost mining and furnace count. Copper-short? Expand copper furnaces and move circuit production closer to the copper source to minimize transport lag. Circuits are hungry enough that proximity helps dramatically.

Labs can multiply by count but not without supply. Keep red flowing first, add green capacity, then increase lab count. Research labs are consumers, not producers.

90-Minute Mark: Green Science Stability and Steel / Defense Fork

Assumption: red science runs; green science unlocks.

Task: ensure green packs arrive continuously. New ingredients (belts, inserters, circuits) mean new bottlenecks. Splitters here ensure research supply wins priority over other builds. Semi-automated → fully automated; hand-supplements vanish.

Identify next fork: steel or defense?

Steel path: Steel costs 5 iron plates. Pursuing steel without iron headroom strangles research or building. Expand iron capacity first, then steel. Place steel furnaces separately, feeding from dedicated iron lines. Steel's weight is real; mismanaged, it craters the whole factory.

Defense path: Pollution neared nests? Biters ramping up? Research military + ammo tech, build supply lines for bullets and turrets. Splitters priority-route ammo; underground belts carry supplies to turrets. Defense only holds if bullets arrive fast.

Power expands too. Green science, circuits, steel (or military ammo), and extra labs all demand more watts. Boiler 1 + steam engine 2 units keep popping up—grid capacity follows factory growth.

Common Pitfalls and Fixes | Research Lags, Resources Vanish, Enemies Overrun

Research Crawls: Bottleneck Diagnosis

Feeling research is slow? Before adding labs, ask: where do materials stop?

Check power first. If the generation graph maxes out, power is your culprit, not research. Boiler 1 + steam engine 2 units scale neatly; add what you lack. Steam engines each do 900 kW, so the math is transparent. Beyond generation, verify stone coal arrives steadily. Furnaces without fuel produce nothing.

Power stable? Next, check science supply. Red or green? Red stalls? Assembler 1 (0.5 speed) struggles. Add a second assembler, or ensure iron/copper flow freely. Green stalls? Circuits, likely. Circuits depend on copper and iron wire. Isolation matters: copper → wire → circuits in a direct line, not tangled through the factory.

A wild card: if you started steel, iron demand explodes. Steel (5 iron → 1 steel) robs iron from research, inserters, and belts. Green research stalls because iron diverts to steel. Symptom: research is slow, not "no science packs," but "too few iron plates to feed everything."

Systemic cause: research halts from supply failure, not research lab failure. Labs scale by number if supplied. If not, more labs just stall.

Resource Gaps: Shortage Triage and Boost Order

Resources feel scarce? Treat each shortage separately. Blanket expansion wastes effort.

Coal drought hits hardest: both steam engines and furnaces depend on it. Furnaces starve, power drops, entire factory cascades. Add fuel-mining drills to the coal patch, individual machines, ramping output. Boilers and furnaces burn coal; route it via splitter to prioritize power, let excess supply smelters. Coal starvation is compounding, so fix immediately.

Iron bias (expanding iron, ignoring copper) leads to copper starvation mid-green. Copper circuits spread everywhere: research, inserters, turrets, higher assemblers. Red science shows full, but green science pieces are missing circuits. Symptom: green slows despite plentiful red. Copper, not iron, is the real issue. Expand copper furnaces and move circuit production close-by (to minimize transit waste). Copper → wire → circuit in a tight line beats a sprawling chain.

Iron pure shortage (gears, steel, belts competing) appears once steel unlocks. Split iron demand: research line, building material line, steel line. Shared short belts breed contention. Dedicated lanes per user avoid this.

Enemies Overrun: Pollution, Scouting, and Defense Ramp

Biters pressure climbs, threatened? Don't delay defense for research. Assaults break production worse than research delay.

Scan pollution reach first. Which nests touched your pollution? That direction needs defense priority. Splitters can direct ammo to threatened zones. Underground belts route supplies across borders. Ammo auto-feed is critical—manual ammo supply bleeds time mid-raid.

Turrets and ammo research bump priority. Military research early-game steals other research time, but factory survival is non-negotiable.

Spatial Cramping: Minimize Rebuild Costs via Early Design

Factories grow and cramped layouts force rebuilds. Best fix: plan 2-3x expansion space upfront. Seems wasteful early; saves enormous time mid-game.

Lay a central main bus or transport corridor early, with side branches for builds. Furnace rows, circuits, research—all organized sideways, not stacked. Spare ground prevents intersections; future structures fit without touching existing ones.

Underground belts help (basic max 4 tiles underground), but space is the real hero. Don't pack furnaces, circuits, labs, and power into tight proximity. Lateral room lets you add rows without redoing central corridors.

Space Age: What Changes? Research Path Shifts from Vanilla

Tech Tree Restructuring Highlights

**Vanilla 2.0 and Space Age feel similar early, but diverge mid-game.** Red and green automation, priority on automation/logistics/power—same foundation. The destination differs.

Space Age (paid DLC, released October 21, 2024) reorganized the research tree. Milestones you'd normally hit—the traditional "end-game checkpoint"—now serve different roles. Early-game bottleneck-solving stays the same; where research leads changes.

Factory design logic mirrors this: early plumbing resembles vanilla, but mid-game targets shift. Self-taught vanilla instinct (e.g., "rocket silo = near ending") doesn't translate. Space Age's silo is a transition gate, not a culmination.

The foundational philosophy persists: automation first, logistics second, power third, then intermediates. But recognize: "which milestone comes next" requires updated mental maps.

Space Age

Rocket Silo Timing Shift

Vanilla places the rocket silo deep in late-game: a hard-won endpoint after massive infrastructure. Feels like a finish line.

Space Age repositions it to mid-game, unlocked via chemical science, as the gateway to space platforms, not the finale. Same silo, wholly different meaning. Reaching it feels like opening a new chapter, not wrapping up.

Implications: if you approach Space Age with vanilla pacing, you'll underestimate what comes after silo launch. I've miscalculated: "reached silo, job done," then discovered the actual silo's role is supply-side of space platforms, and underpreparation hit hard.

Space Platforms as the Real End Target

Space Age shifts from "launch rocket" to "establish foothold off-world." The silo is a tool, not a trophy. Spatial Networks (Space Age required) shows the scale of what awaits: ground and space in tandem.

This reshapes factory thinking. Vanilla asks: "how do I maximize ground production into rocket ingredients?" Space Age asks: "what should I funnel skyward, and in what ratio?" The silo is supply source to off-world needs, not a monument.

Early-game strategy (automation, logistics, power, circuits) works unchanged. The pivot comes mid-game when silo context reshapes research urgency. Plan accordingly, and mid-game transitions smoothly.
