How to unlock: You have to craft a weapon or an armor with at least three Augments.
Commentary: You can install augments while crafting high-level gear (Level 2 and higher). You have to have at least three augments in your inventory - they can be found, crafted, or bought. This mechanic is described in detail in the crafting chapter.
The trophy is easy to get, but you will need two things - a weapon that you can install at least 3 Augments in and at least 3 Augments. Augments can be purchased from vendors, as well as researched at the Research Center. There will be more problems with the weapon - you have to research a proper blueprint at the Research Center, but you shouldn't have problems with Research Data when you have access to the mentioned Augments.
Once you've got all the necessary ingredients, interact with the Research Station, go to the Development tab, select the weapon / armor blueprint with at least 3 Augments slots and place those Augments into the slots. Now craft the weapon to get the trophy. Don't worry - you can deconstruct the item to regain all of the Augments used in the process.
