Sequential Fabricator

Sequential fabricator

A sequential fabricator (also known as a crafter) is a machine that crafts items.





A sequential fabricator is initially at the lowest tier (basic). It can be upgraded to higher tiers using upgrade kits and conversion kits.



When placed, a sequential fabricator faces the player. It can face any of the four cardinal directions, and can be rotated using a wrench.


A sequential fabricator must be configured to perform a specific crafting recipe in order to function.

When the required items for the configured recipe are placed in a sequential fabricator’s input slots, the machine will start consuming Redstone Flux to craft items. The machine requires 400 RF per operation. When enough energy has been consumed for an operation, the input is consumed and the output is placed in the output slot.

When installed, fluidic fabrication allows a sequential fabricator to use fluids, which are stored in an added input tank.

The speed at which a sequential fabricator crafts items depends on how much energy it can use per tick. This in turn depends on how much power is being supplied, and on the machine’s maximum power usage. A basic sequential fabricator has a maximum power usage of 20 RF/t. This can be increased by upgrading the machine to a higher tier, and by installing certain augments.

Input and output

Items and fluids can enter and exit a sequential fabricator through its sides. Every side of a sequential fabricator may correspond to its input slots (and possibly its input tank), its output slots, or certain slots/tanks at the same time.

A sequential fabricator can automatically transfer items out of any sides that directly correspond to one of its output slots. This is called auto-output. If pattern validation is installed, it can also transfer items from adjacent inventories into any sides that directly correspond to its input slots. This is called auto-input. Auto-output and auto-input occur whenever the machine finishes crafting an item, or every 32 ticks (1.6 seconds) if the machine is inactive.

A basic sequential fabricator can automatically transfer up to 16 items at a time. This amount can be increased by upgrading the machine to a higher tier.


Redstone control

A sequential fabricator may be configured to respond to redstone signals. It can be in one of three modes:

Redstone control is disabled. The sequential fabricator works whenever possible. This is the default mode.
The sequential fabricator works when not powered. When powered, it stops working.
The sequential fabricator only works when powered.

The current mode can be set using the Redstone Control tab in the machine’s GUI.


A sequential fabricator can have a signalum security lock installed to restrict who can access it.


A sequential fabricator’s configuration can be saved on a redprint to be copied to other sequential fabricators.

Light source

When a sequential fabricator is active, it emits a light level of 7.


Sequential fabricators come in five tiers.

Tier Max. power usage Augment slots Max. items per auto-transfer
Basic 20 RF/t 0 16
Hardened 30 RF/t 1 16
Reinforced 40 RF/t 2 28
Signalum 50 RF/t 3 44
Resonant 60 RF/t 4 64


A sequential fabricator can have augments installed to improve certain properties or to change how it works. The amount of augments that can be installed depends on the machine’s tier. A basic sequential fabricator cannot be augmented.

Augments can be installed in the Augmentation tab in a sequential fabricator’s GUI.

Augment Installable in Description
Auxiliary Reception Coil Auxiliary Reception Coil Any machine Increases a machine's maximum power usage (speed). However, also increases the amount of energy required per operation. Can be installed multiple times.
Pattern Validation Pattern Validation Sequential Fabricator Allows for a sequential fabricator to handle item input more intelligently. Two input slots are designated for each crafting slot. Also allows auto-input to be enabled.
Fluidic Fabrication Fluidic Fabrication Sequential Fabricator Allows for a sequential fabricator to craft recipes that include a fluid container item (such as a filled bucket) using fluids from an added input tank.
