{{About/Space age}}
The '''Biolab''' is an upgraded version of the [[lab]] that is unlocked by researching the [[Biolab_(research)|Biolab technology]]{{SA}} using [[Agricultural science pack]]{{SA}} from [[Gleba]]{{SA}}. It boasts a number of advantages over the standard lab:

* Biolabs have a built-in speed bonus, meaning research is processed twice as quickly (effectively a 100% speed bonus)
* Biolabs have 50% science drain, meaning they consume half as many packs for the same amount of research progress
** Put together, the above two points effectively mean the biolab consumes science packs at the same rate as the regular lab, but gives double the research progress. This is like a productivity bonus, except it stacks multiplicatively rather than additively with other bonuses.
* Biolabs have four [[module]] slots instead of two.
* Biolabs are larger (5x5) and have more health.

It features minimal disadvantages:

* They are more complicated to create, involving [[Biter egg]]s which require [[Bioflux]] to acquire.
* They may only built on [[Nauvis]].
* They use more power and pollute more.

The speed bonus granted from [[lab research speed (research)|lab research speed]] multiplies with the Biolab's increased speed.

Inserters

''For the common yellow electrical inserter, see [[Inserter]].''

'''Inserters''' are devices which are used to move items over short distances. When placed, they have a fixed direction. They can move items from behind and place them in front of them. By doing this, they can move items from one transport belt to another, but also extract items from—and insert items into—machines or storage devices.

== Types of inserters ==
{| class="wikitable"
| {{Imagelink|Burner inserter}} || The only [[fuel]]-powered inserter, with the slowest speed.
|-
| {{Imagelink|Inserter}} || The standard electrical inserter.
|-
| {{Imagelink|Long-handed inserter}} || Capable of inserting and removing items from a greater distance.
|-
| {{Imagelink|Fast inserter}} || Much faster than the inserter.
|-
| {{Imagelink|Bulk inserter}} || As fast as the fast inserter, but can move many more items at the same time at once.
|-
| {{Imagelink|Stack inserter|space-age=yes}} || As fast as the bulk inserter, but can stack items on a belt.
|}

== Mechanics ==
Inserters '''will''':
* Pick up items off the ground, off of a [[Transport belts|transport belt]], or from any object that has storage space, such as [[Chests|chests]], [[furnace]]s [[assembling machine]]s or [[vehicle]]s.
* Place the item onto the ground, onto a transport belt, or into any object that has storage space.
* Run at slower speeds when starved for energy.
* Pick up as many items as their [[inserter capacity bonus (research)|stack size]] allows at once, if they do not have to wait too long to pick them up.
* Pick up items and drop them into the void of space or lava, permanently destroying them. This is useful for getting rid of unwanted items.

Inserters '''will not''':
* Pick up any items that cannot be inserted into the adjacent entity.
* Pick up any items if the adjacent entity is a [[ghost]].
* Pick up items to place into an entity with a full inventory.
* Place more than one item at a time onto the same ground tile.
* Place items into an entity that cannot hold them, for example due to [[Stack#Filtered_stacks|filtered]] or [[Stack#Stack_limitation|limited slots]].
* Fill up the entire target inventory of [[boiler]]s, [[nuclear reactor]]s, [[:Category:Producers|production building]]s, [[furnace]]s and [[turret]]s.

If two or more inserters are picking up from the same tile, the inserter who can grab the items the fastest will grab them first. Besides faster inserters, this favors inserters taking from the inner lane of a transport belt.

=== Insertion limits ===
Depending on where an inserter is moving items, it does not always fill up the entire target inventory. This allows other inserters taking from the same transport belt to pick up their share of the items. For example, if a boiler has 5 or more items of fuel in it, an inserter will not insert additional fuel. This allows the other fuel to travel further down the transport belt. When the fuel drops below 5 items, the inserter will resume inserting fuel, up to the limit of 5 items.

An inserter that has a higher [[inserter capacity bonus (research)|inserter capacity bonus]] than 1 can overfill the target building, due to the inserter picking up a higher amount of items than needed. Overfilling can also occur if multiple inserters are used to insert items into one building.

=== Inserters and transport belts ===
[[Transport belts]] have two lanes on which items can travel. Inserters only place items onto one side of the belt, either the far side from the inserter's perspective or if the belt is going the same or the opposite direction as the inserter the right side from the belt's perspective.

{|
| style="width:320px;" | [[File:Inserter_dropoff_locations.gif]] || [[File:Inserter_pickup_locations.gif]]
|-
| style="width:320px;" | Inserters place the item on the furthest lane. If a belt is in the same orientation as the inserter, the item will be placed on the right-hand lane, from the belt's perspective. In curves the inserter always places on the far side.
| style="width:320px;" | If the belt is perpendicular to the inserter, inserters '''prefer''' taking items from the nearest lane. If the nearest lane is empty, the inserter will take from the far lane. If the belt is the same/opposite orientation of the inserter or a curve, the inserter '''prefers''' taking from the left lane, from the belt's perspective. If the left lane is empty it will take from the right lane.
|}

=== Potential issues ===
Inserters may have problems picking up items:

* From very fast belts, because the items are moving too quickly.
* From the entry or exit of an underground belt (because the time they have to pick up is shorter)
* From turning belts if the item is on the inside of the corner

== Power usage ==
Inserter power draw is determined by several factors.

Firstly like most machines, all of the inserters (with the exception of the burner) have drain. Drain is the energy cost of existence, and is expended constantly as long as the inserter exists on the power grid, regardless of activity or lack thereof.

Inserters also have a cost associated with movement. This cost is applied separately and cumulatively for rotational motion as well as extension/retraction.

Lastly, inserters exhibit a power spike when initializing an action or movement. This can be referred to as "item spike" because it is typically observed directly upon picking up an item. This is because after receiving an item, it will initialize its next action, such as unloading the item. We know this spike is a result of the initialization of a new command for the inserter, and not directly as a result of the item, because of behavior that will be covered later. In other words, the spike occurs when switching between loading and unloading behavior.

Here is power graph of a red inserter receiving power for the very first time:

[[File:Red Power Pulse.png|frameless|upright 3]]

Notice there is a spike as it boots, followed by a movement line. This movement line is the cost of rotation + the cost of extension, as inserters start scrunched up when first built, and then the arm extends. This specific behavior is only exhibited by newly built inserters receiving power for the first time, so we can largely ignore the behavior on the left. It is worth remembering for when devising a testing setup though, as this does need to be isolated out of the final results for accuracy. It will also become relevant again further down.

Continuing on, we have the power signature of a single item being transferred chest-to-chest. First there is a spike when retrieving the item. Even though the spike is flattened, implying a duration, upon closer inspection it does appear to only be a single tick duration of spike. It is not clear from the testing why these peaks are flattened while the initial is not. The arm then begins rotating, and its cost of rotation is shown by the valley. It then drops off the item, resulting in a second spike, and proceeds to swing back towards the input. This completes one full cycle.

Notice how when not active, the consumption remains above 0. This is the drain we discussed earlier, which in this example is 400W.

Burner Inserters, despite not using electricity, also have the same power consumption characteristics as the rest of the inserters (excluding drain). Upon accepting fuel they will replenish something resembling an internal battery, and draw from it in the same manner other inserters draw from the power grid, consumption spikes and all. The exact behavior of burners is a bit quirky due to how this works, and that can be found in more detail on their dedicated page [information not yet added].

[[File:Inserter Testing Setup.png|thumb|Inserter Testing Setup]]

=== Energy Costs ===

Using the following equation and empirical testing, we derive the values below. Note that values for burner inserters are derived with coal as a baseline. The fuel density used in the burner actually affects its measured values due to some quirks with how they operate, with higher fuel densities leading to improved performance. More detailed information for all inserters is available in the original forum post here ''https://forums.factorio.com/124635'', where the entirety of the calculations is shown and documented in detail for those interested.

((Max Power Consumption - Drain) * (2 /seconds per tick)) + ((Power Consumption of Motion - Drain) * ((Full Rotation Constant / Rotation Speed) - (2 / seconds per tick))) = kJ per Inserter Rotation

=== Inserter Efficiency ===

The above data can be used to compare inserter efficiency directly. Remember that the transfer cycle cost remains the same regardless of how many items are moved (with one exception that will be covered later). This means that Green Inserters with their larger stack size can outperform other inserters despite their higher transfer cost, since they can achieve a lower cost per item. Here are some graphs of chest-to-chest data showing the efficiency of different inserters at differing stack sizes. Because the other inserters maintain a proportional relationship (as in an identical stack size) these graphs will primarily focus on highlighting the Green Inserter.

<gallery mode="slideshow">
File:Inserter Efficiency Graph (No Capacity Bonus).png||No Capacity Bonus

File:Inserter Efficiency Graph (Capacity Bonus 6) (Zoomed).png|Capacity Bonus 6
File:Inserter Efficiency Graph (Capacity Bonus 7).png|Capacity Bonus 7
</gallery>

Because the Burner Inserter doesn't have drain, its efficiency can only be appreciated in extremely low throughput situations. Thus we use this dedicated graph:

[[File:Inserter Efficiency Graph (Burner Version).png|frameless|upright 3]]

Because of how extremely low the throughput is, generating additional graphs for higher stack sizes is unnecessary. At higher stack sizes simply divide the reference time by the stack size.

=== Belt Differences===
Up until now all data was regarding chest-to-chest use cases, due to their sterile and consistent nature. The introduction of belts creates special conditions that require consideration. Here is a power chart from the game for reference:

[[File:Yellow Inserter Belt-to-Belt Power Signature.png|frameless|upright 3]]

The Yellow Inserter above is doing a belt-to-belt transfer, and it has a stack bonus.

The erratic section of the graph is the loading process. We can see the behavior is irregular as the inserter does not wait for the item, but rather fishes around for them. The exact behavior here is still being studied, and due to its dependence on stack size and belt speed it is very difficult to give any firm answers regarding how much power this actually uses as a quantifiable generalization. Likely a set of tables would need to be generated with every possible combination as a reference, but such data does not currently exist. We can see the movement section seems to as an average indicate the combined cost of rotation and extension/retraction (this is not covered here as detailed data does not exist, but the games code suggests these two costs are identical), which we saw in our original power pulse earlier. This would make sense as the inserter is moving inwards and outwards as well as wiggling side to side as it fishes for items, but this isn't confirmed, and could be inapplicable in faster use cases. To add to the hypothesis, we can assume that faster belts increase inserter efficiency by shortening the loading time. But that's all speculative until more data is collected. What we can confirm is at the end of the loading cycle we have our distinctive power spike, which is indicative the inserter is now switching to unloading.

Looking at the unloading section, we can see the inserter swings around normally, but then there is this dip that doesn't exist in the chest to chest behavior. This is the inserter waiting at the belt to drop off all its items. During this waiting, it uses no power aside from its drain. Once all the items are delivered, it spikes, indicating it is going back to its loading behavior.

What this means in practice is whenever you are loading from a chest, regardless of whether you are delivering to a chest or belt, the efficiency relationship remains the same. The additional duration of drain has no bearing on the energy efficiency. When loading from a belt, we can see there is additional energy consumption for stack sizes greater than 1. Currently there is not much that can advised regarding how to compensate for this, so the best advice is to just pretend it doesn't exist for now.

'''Important:''' The above efficiency graphs only apply when loading from a chest. When loading from a belt, until a more accurate dedicated data set is provided, it is advised to reference the initial no capacity bonus version of the graph for all decisions. With an inserter stack size of 1, the efficiency relationship between chests and belts is identical.

'''Regarding Quality:''' Quality inserters receive a linear speed boost for each level of quality, with a corresponding power cost increase. What this means is that the quality level of an inserter has no impact on its energy efficiency

''More data regarding inserters feeding from belts, as well as more detailed data regarding burner inserter power consumption is still needed. Please reach out via the forum if you would like to help or contribute in collecting this data, either here https://forums.factorio.com/124635 or here https://forums.factorio.com/125710''

'''Note:''' These numbers come directly from the [https://github.com/wube/factorio-data/tree/master/base/prototypes/entity factorio-data github repository].

=== Rotation Speed ===
Convention: 2π rad = 100% of a circle rotation = '''1 turn''' (or one full rotation).

Note: an Inserter doesn't always need to make full turns. When grabbing from a transport belt, it is slightly faster when grabbing items from the closest lane.

Note: If the rotation speed of an inserter would result in an odd number of ticks per full turn, the actual number of ticks per full turn for this inserter is the next higher even number. The reason for this is that the inserter needs to do two half turns to pick and drop an item. This takes a certain number of ticks two times, therefore the number of ticks for the full turn is always an even number. Example: The Fast inserter's rotation speed of 864°/s or 0.04 turns per tick would result in 25 ticks per full turn, but the inserter cannot do a half turn in "12.5 ticks", so it actually takes 2*13 = 26 ticks per full turn.

=== Extension Speed ===
The extension-speed is normally not visible (only when compared to other inserters), but there are measurable speed differences when taking - for example - from the near or the far side of a belt. Also Some mods can alter the pickup and drop locations of inserters, making this stat more relevant.

== Inserter Throughput ==

=== Chest to chest ===
'''Note:''' Experimental data from 2.0.26, recorded in this doc [https://docs.google.com/spreadsheets/d/1L8Td5o6TAicGi-TPwzh4lz2YiH0n7Jkpp3E8FxNpnAs/edit?usp=sharing]. Chest to chest transfer transfers the entire hand size during a single tick, so most of the time is spent during the swing to and from.

=== Chest to belt ===
Throughput going from chest to belt depends on how full the belt is. An inserter will not put down an item on a belt that have items back-to-back (aka full compression) - it waits until there is a gap. However, if the gap is narrower than the item then the items upstream on the belt will stop to make room for the item being inserted. The direction of the belt compared to the inserter does not matter however.

In these measurements inserters move items onto an empty belt. Values are given for the stack sizes at three different [[inserter capacity bonus (research)|capacity bonus]] levels.

=== Chest to splitter ===
When an inserter drops items onto the side of a perpendicular splitter, it always is considered to do so on the input side, enabling the splitter to move half of the items to the other belt (assuming that the splitter filter/priority settings allow it to do so and that there is available space on both belts). This allows the inserter to drop its items twice as fast. A fully upgraded bulk inserter can drop twelve items onto an express splitter every 38 ticks (18.95 items/second) instead of the usual 52.

[[File:Inserter to splitter comparison.png|621px|thumb|center|By inserting onto the side of a splitter, a fully-upgraded bulk inserter can fill 84% of an express belt lane instead of the usual 62%.]]

When picking items from a belt, many more factors come into play besides belt fullness:

* How fast the items move (i.e. if they are queued up on the belt or move at belt speed).
* Whether the belt is perpendicular to the inserter or approaches it head on.
* Whether items are on the near or far lane of a perpendicular belt.
* Whether the belt turns or not, and whether the items are in the inner or outer side of the bend.
* If the belt is an underground entrance or exit. This shortens the time items are visible to the inserter for pickup.
* All sorts of intricate timing factors between the inserter and the items on the belt, since the game simulates the arm homing in on every item.

The test setup used below is with an inserter taking items from a perpendicular belt with items on the far lane only. The belt is fully compressed and timings are both for items that move at full speed and queued up as much as possible. Values are given for the stack sizes at three different [[inserter capacity bonus (research)|capacity bonus]] levels.

<nowiki>*)</nowiki> Throughput for basic/fast/express belt.

Since there are many more factors involved, these measurements exhibit a more complex pattern than chest-to-belt.

* Boldface cells show for which belt each inserter has the best throughput on each bonus level when items move at belt speed. Higher speed belts mean that inserters have to work harder to catch the fast moving items. The effect is most noticeable for slower inserters and smaller stack sizes.
* When items are queued up the belt type hardly matters, so there is only a single column for that. The exceptions are the stack inserters - for basic transport belts it's the belt that sets the limit for stack sizes above 4, and there is also a notable difference between fast and express belts.

=== Belt to Chest (facing inserter) ===
'''Note:''' Experimental data from 1.1

When picking up items from a belt facing the inserter, there are multiple small differences between different setups. The following throughput tests are performed with [[express transport belt]]s and [[bulk inserter]]s with the maximum [[inserter capacity bonus (research)|capacity bonus]].
Each setup in the following picture shows the amount of ticks per cycle of the inserter and the amount of items per second the inserter moves. These measurements are consistent in all orientations of the setup.

[[File:modules_preview.png|right]]'''Modules''' are items used to enhance existing buildings' capabilities. They are expensive, require appropriate [[research]], and are produced slowly, but can eventually greatly improve the efficiency of a factory.

Quick usage summary:
*For more products per second a speed module should be used.
*For more products per input resource a productivity module should be used.
*For more products per watt of energy an efficiency module should be used (except in rare cases when productivity modules are also used - then a speed module might be better).

Note that changing a machine's energy consumption directly affects how much pollution the machine generates. This is the case because the pollution production rate is directly linked to the machine's energy consumption, so this applies even when power is produced in a pollution-free way.

== Types of modules ==

There are three types of modules in ''Factorio'', each with 3 tiers of effect. Higher tiers have stronger effects but are more expensive. Note that the machine's properties (speed, energy consumption and pollution) cannot be reduced below 20% of the original value.

=== Speed module ===
Speed modules increase the speed and energy consumption of a machine.

{| class="wikitable"
|-
! Module !! Speed bonus !! [[Electric system|Energy]] consumption
|-
| {{Icon|Speed module}} || +20% || +50%
|-
| {{Icon|Speed module 2}} || +30% || +60%
|-
| {{Icon|Speed module 3}} || +50% || +70%
|-
|}

Advantages & Disadvantages:

* Increases speed of machine. 
* If used with productivity modules, it can increase the efficiency of the machine in terms of items produced per joule (or items produced per pollution generated). 
* Increases energy use per cycle (exceptions exist). 
** Increased energy usage means increased pollution generation (pollution depends on power usage). 

----

=== Productivity module ===

Productivity modules add a purple "productivity bar" when placed inside item-producing buildings and [[lab]]s. If the productivity bar is already present through completed research, the modules will simply speed up the bar. Each time the machine finishes crafting the recipe it is set to, an amount is added to the bar equal to the percentages of the productivity modules inside the machine. When the bar reaches 100%, an extra set of products is immediately generated without consuming any resources.

Productivity modules can only be used in machines that are set to make [[:Category:Intermediate_products|intermediate products]]. These are all the ores mined by electric drills, the stone brick (and anything else smelted in a furnace) and some of the items listed in the intermediate products tab. Exceptions to the items listed in this tab are the recipes that fill/empty a barrel. Productivity modules cannot be placed in [[beacon]]s either. When a recipe uses the same item as an input and output (e.g. [[coal liquefaction]] and the [[kovarex enrichment process]]) the productivity bonus only applies to the net product [https://www.factorio.com/blog/post/fff-256].

{| class="wikitable"
|-
! Module !! Productivity bonus !! [[Electric system|Energy]] consumption !! Speed !! [[Pollution]] multiplier
|-
| {{Icon|Productivity module}} || +4% || +40% || -5% || +5%
|-
| {{Icon|Productivity module 2}} || +6% || +60% || -10% || +7%
|-
| {{Icon|Productivity module 3}} || +10% || +80% || -15% || +10%
|-
|}

Advantages & Disadvantages:

* Creates an additional free item occasionally. 
* Increases energy use per cycle. 
* Increases pollution generated. 
* Slows the machine. 

----

=== Efficiency module ===
Efficiency modules reduce the required electricity to run the machine. The lowest amount of energy that efficiency modules can be used to achieve is 20% of the machine's base energy usage.

{| class="wikitable"
|-
! Module!! [[Electric system|Energy]] consumption
|-
| {{Icon|Efficiency module}} || -30%
|-
| {{Icon|Efficiency module 2}} || -40%
|-
| {{Icon|Efficiency module 3}} || -50%
|-
|}

Advantages & Disadvantages:

* Reduces energy use per cycle. 
** Decreased energy usage means decreased pollution generation (pollution depends on power usage). 
* Cannot lower energy usage below 20%. 
* If used with productivity modules, sometimes the efficiency gain is lower than what a speed module could achieve. 

=== Quality module ===
{{About/Space age}}
Quality modules increase the chance of items being produced in higher qualities, which in turn grant bonuses which makes items and buildings work more efficiently. Higher quality items have a lesser chance of being created. Note that quality modules themselves can be made with higher qualities, which further increases the chance of higher quality products being made.

{| class="wikitable"
|-
! Module !! Quality bonus !! Speed
|-
| {{Icon|Quality module}} || +1% || -5%
|-
| {{Icon|Quality module 2}} || +2% || -5%
|-
| {{Icon|Quality module 3}} || +2.5% || -5%
|-
|}

Advantages & Disadvantages:

* Can provide higher quality items. 
* Quality modules themselves can have higher quality. 
** Modules with higher qualities have larger bonuses, further increasing the chance of better items being made. 
* Slightly decreases speed of buildings. 
* Not all higher quality items have bonuses. 

== Usage tips ==

As a rule, the effects of multiple modules are '''additive, not multiplicative''', meaning they don't have diminishing returns (except that consumption is capped to -80%), so if an assembler is making 2 items per second, adding one speed module 3 (+50% speed) will increase item production by 1/s, and a second speed module 3 will increase production by another 1/s. Consumption modifiers work the same way, for example if a machine is consuming 180kW, the first efficiency module 1 will reduce energy use by 54kW, the second will also reduce energy use by 54kW. There is no difference between putting two speed module 1's in one machine and two efficiency module 1's in a second machine, compared to putting one of each in both machines - in both cases the total items produced per second and average energy required per item is identical.

There is however synergy between productivity modules and speed modules, productivity modules reduce crafting speed which lowers the production rate of items and increases the energy consumed per item, the speed bonus from speed modules increases production rate of items and lowers the energy consumed per item - in fact when dealing with productivity modules, the reduction in energy consumption from the increased speed from speed modules can be greater than the increased energy consumption. For detailed calculations on the synergy between productivity modules and speed modules refer to [http://www.factorioforums.com/forum/viewtopic.php?f=5&t=5705 this discussion] as well as [https://forums.factorio.com/viewtopic.php?f=16&t=59989 this warning].

Filling the device with '''speed modules''' is useful when a resource is infinite but the amount of resource pools is low. The best example would be '''oil deposits'''. Another good place to use speed modules would be for assembly machines which make products that take a long time to make, for example engine units. Using speed modules allows more compact setups, because one machine can provide materials to more consumers than normal. If used together with productivity modules, they can also increase efficiency (in terms of items produced per watt or per pollution generated) of a machine.

Filling devices with '''productivity modules''' is recommended when resources are scarce. An example would be more advanced products not being produced enough due to bottlenecks. It will take longer and more energy, but the overall amount of products per time will be higher. Productivity is especially useful in recipes that consume a lot of resources per second such as [[electronic circuit]]s, as this will result in a lot of free items being created and quickly cover the cost of the module. Also by saving the need to mine ore, smelt plates and process intermediates for those free items the additional energy cost can be easily covered.

Filling devices with '''efficiency modules''' is recommended for electric furnaces as these use a lot of power. Note that making higher level efficiency modules are not worth it in terms of power saved vs materials used to build a [[solar panel]] setup with same power output so the only incentive is to further reduce pollution or space utilization. Modules are also able to control [[pollution]], as '''pollution depends also on [[Electric system|energy]] usage'''. So reducing a machine's energy usage by 40% with a efficiency module 2 will also reduce its pollution by 40%. Beware as this also works vice versa! Also note that if you're using productivity modules, a speed module can sometimes provide better efficiency gains due to the fact that the machine will now be producing much more items per second. Efficiency modules also generally don't work well in beacons.

=== Examples of usage ===
[[Electric furnace]]s are huge power hogs at 180 kW per furnace. 1 basic efficiency module reduces it by 54 kW (−30%) – almost a [[solar panel]] worth of power. [[Electric mining drill]]s normally create 10 units of [[pollution]], using 3 basic efficiency modules on them reduces their pollution production by 80% to 2 units per minute.

Using productivity module 3s in the [[rocket silo]] reduces the total resource cost for 1 rocket launch by almost 30%, saving 26k copper ore per rocket launch.
