i have a few suggestions for this:
1: add a blueprints tab in the inventory/crafting area to see what blueprints you have
2: whenever you have a blueprint it appears in the crafting menu
3: blueprint/non blueprint wipes
i just find it so annoying when you get raided and have to farm for ALL of the blueprints you had before
this could also allow for a tech tree of sorts and maybe even different tier workbenches
