You'll have to wait until you've unlocked at least 5 blueprints to complete this achievement. Once you have the blueprints, interact with an upgrade station and ensure you have enough materials to create each blueprint at least once.
The beauty of Atomic Heart is that you can dismantle any found/created weapons for 100% of their materials. So you could craft a weapon, dismantle it and then use those materials to then make the next weapon.
At the moment you'll need to do all 5 in one sitting as the achievement tracking resets back to 0% when you close down your game.
