How to unlock the Weapon Smith achievement in Warframe - Definitive Guide
I attained this achievement through story mode. You unlock the foundry by playing through the story. Once you save the merchant from prison he gives you the Ascaris Negator, but you don't have enough parts for it. So you have to complete another mission to get you the parts to make this item. Once you make it, the achievement should pop.
