Made to Order
In order for you to make items, you need crafting materials. To obtain crafting materials you take any item go to the blacksmith, hit RB to the salvage part. Just about every item in the shop also requires a new thing called Common Debris which you get from salvaging white items, so in order for you to obtain this achievement (especially for Imported characters) You need to find some common debris or salvage white items.
Once you have some materials just go to the armor area or weapons and build anything you can 5 times, if it doesn't unlock, dont worry the games achievements are buggy atm and it will unlock sometime later, I have had several achievements do this to me.
