The Crafter block is a redstone-powered crafting station that automates item production. Unlike a regular crafting table, it stores ingredients and crafts on demand.

What Is a Crafter Block?

A crafter is a low-capacity storage block that can use its contents to craft items when given a redstone signal, ejecting the results into the world or into a container it is facing.

Inventory and Slot Locking

A crafter has nine slots of inventory space, arranged in a 3-by-3 grid like a crafting table. Its GUI can be accessed by using it. A slot can be enabled or disabled, which can be toggled by clicking on it when empty. Disabled slots cannot have items put in them.

Its inventory slots can be individually locked so hoppers and similar blocks cannot fill them, while not affecting crafting recipes.

Redstone Crafting

When a crafter receives a redstone signal, it waits for 4 game ticks (0.2 seconds) before ejecting one crafted item using the ingredients from the nine inventory slots. The crafted items are subsequently ejected from the front of the crafter. If the front of a crafter is facing a container (including another crafter), the crafted items are transferred into the container.

Automatic Crafting

Because disabled slots prevent items from entering the slot, crafters can be used to craft any item in the game automatically without any input from the player, using a series of hoppers and/or droppers and the correct configuration of disabled slots for the recipe.

Comparator Output

A comparator placed next to a crafter can read its state. The signal strength equals the number of crafting slots that are either disabled or occupied by an item. The stack size of the items does not affect the signal. This is useful for monitoring the crafter's status in redstone circuits.

Edition Differences

In Java Edition, unlike dispensers and droppers, crafters are not affected by quasi-connectivity. Additionally, crafters cannot be moved by pistons in Java Edition. These differences matter when designing compact redstone circuits. For more on choosing between editions for speedrunning, see our guide on Java vs Bedrock for speedrunning.
