The IC Blueprint is an item by Project Red. It's used to create own individual redstone circuits on the IC Workbench, which may then be integrated into an empty IC Chip with the IC Printer. The created IC Chip can than converted into an individual IC Gate.
If the mod MineChem is installed, then you can decompose the IC Blueprint with the Chemical Decomposer into 4 Lazurite and possible some other compounds of MineChem.
