The 3D Printer in Modern Warfare 4 DMZ allows you to create some equipment like the Tempered Armor Vest. But in order to do that, you must first unlock the recipes. In this guide, we’ll explain how to unlock the 3D Printer, defeat the Doctor, find his key, and get the Tempered Armor Vest recipe.
How to Unlock the 3D Printer
The 3D printer is available in MW 4 DMZ after achieving Level 2 and finding it in your FOB. You can fast-level up by playing a game where you get loot and extract successfully. You don’t have to finish all missions or extract successfully in order to achieve this level. Once you get your hands on the 3D Printer, you can start working on acquiring new recipes for crafting. Another thing that you will need is a key, which will help you enter a locked room with a blueprint.

The first thing you need to do is find and beat the Doctor, who is available in the medical zone. Be sure you have all the necessary gear before entering the battle with him, since there are also some enemies around. After you defeat the Doctor, get his loot and find the key that drops from him.
Do note that the boss’s dog tag and key are not one and the same; while the former allows you to complete the bounty mission and update the board, the latter is the key to entering the locked room that houses the blueprint. Once you obtain the key, remain in the zone and prepare to explore the upper-floor offices. Once you obtain the key, remain in the zone and prepare to explore the upper-floor offices.

This key is used to unlock a room in the upper-floor office areas. Go up the stairs and locate the conference room with the lock using the key. The room you will find here is known as the converted conference room. Using the key, unlock the room and enter.
Inside, you will find a weapon manual that holds the recipe for the Tempered Armor Vest 3D Printer. Get the manual to unlock the recipe. Once obtained, the recipe becomes accessible on your 3D printer. This lets you create the Tempered Armor Vest after getting all the resources.
How to Use the 3D Printer
First, you need to unlock recipe blueprints to use at the 3D Printer. The only way to unlock recipes is to continue completing missions and obtain them randomly as rewards. Then, you can make your way to the 3D Printer placed at your FOB and select the recipe that you wish to craft. Crafting items will require several different material types, and you can find the requirements while checking out the recipe. You can obtain these materials during missions too, so collect whatever you can and exfil with it so you can use it to craft various types of gear.
