This page is meant to list the blueprint pages in a more useful manner than just the Category Page

Blueprints are items that can be equipped on user bases and enable a user to build the item stated in the blueprint. They specify what initial and periodic materials are required to build the item, the cost to build, the time taken (in Manhours), and the skill specific requirements if any. Blueprints do have tech levels, and a blueprint cannot be equipped on a base unless the person equipping has the prerequisite skills. You can equip blueprints of higher tech on a lower tech base if you have the station management required for the blueprint.
