Just completing? Unlocking these specific blueprints don't require S rank?
I've done a little more research and it seems that I was wrong, there's more to it than that.
Apparently sample Gummi Ships use certain gummies, which you get as treasures by destroying red and gold enemies, meaning that you can't get a blueprint if you haven't obtained the gummies associated with it. Each sample blueprint has a different level and all of its gummies are found in a specific route (Highwing's, Falcon's and Invincible's level 1 gummies are found in Asteroid Sweep, while their level 2 gummies are found in Stardust Sweep).
So in order to get all the blueprints, you need to:
-Get each sample blueprint's respective gummies
-Get an S rank on all Assault of Dreadnought's missions.
-Get an S rank on all level 2 Gummi missions
-Obtain the Kingdom Model as a treasure in Asteroid Sweep
Hope this clears things up, the game doesn't tell you which gummies you need for a blueprint so your best bet is to get as many treasures as you can. You don't need every single treasure as I've already gotten the trophy and have yet to collect all of them. I'll check my save again tomorrow in case I've missed something or got something wrong.
