Blueprint

Normal =

Rare =

A Blueprint is an item that lets the player learn a craftable recipe without having to prototype it first. When used, it restores 15. Blueprints themselves do not actually create an item; they only allow the player to craft the item away from the station normally used to prototype it.

Blueprints can be found in some Set Pieces and at the beginning of each world in Adventure Mode.The player can find more than one Blueprint that unlocks the same recipe, and all Blueprints will restore Sanity when used, even if the player has already researched the item.

In the Reign of Giants DLC, Blueprints can also be obtained by destroying Tumbleweed in Sandbox Mode. It is possible to find Blueprints for items in the Ancient Tab, but an Ancient Pseudoscience Station will still be needed to actually craft the item. Ancient Tab Blueprints do not restore any Sanity. Old Bell recipe can only be obtained from a Blueprint.

In the Shipwrecked DLC, Blueprints can be obtained from X Marks the Spot treasure chests.

Don't Starve Together
In the A New Reign DLC for Don't Starve Together, a rare variant of the Blueprint may be dropped, when killing a Dragonfly or a Toadstool. These can used to prototype the Scaled Furnace, the Funcaps, the Mushlight and the Glowcap. Additionally the Rare Blueprint for the End Table can be acquired by hammering the Stagehand.
