For the decorative object found in USCM Bases, see Blueprint Display.
Blueprints are items that allow the player to learn a schematic. Each blueprint is associated with one crafting recipe, called a schematic. Tiy has stated there will be 1300 blueprints at launch, each unlocking a unique schematic.
Blueprints are often found inside chests. Clothing and Weapons Merchants in villages will also sell blueprints of their own race's armor/weapons. While often Tier 1 items, they do occasionally sell higher-tier blueprints.
A schematic can only be learned once. Attempting to use a second blueprint for the same schematic will have no effect, nor will the blueprint be consumed.
