Among the most critical things in MW4 DMZ is the 3D printer, which helps in manufacturing some useful items and upgrading your equipment. However, one needs to be cautious when choosing the upgrades since cash and resources are scarce at the beginning of the game. Some upgrades will help you store more loot, while others will save you some cash. In this guide, we’ll tell you the best 3D printer upgrades to level up first in MW4 DMZ and explain why each one is worth your resources.
Best Upgrades to Get First

Once you unlock the 3D printer in MW4 DMZ, you need to decide which upgrades to focus on first. Some upgrades make your life easier by giving you more storage space, while others help you save money and craft better items.
Stash Upgrade

The first upgrade you need to consider is your stash. With each match, you will end up with several things, such as medkits, crafting materials, and other items of value. However, a lot of items do not stack, and hence your stash is bound to fill up fast. To expand the capacity of your stash is by upgrading it. The first upgrade will cost you 19 Electronic Sensors, Bridge Synthetics, and $10,000, and it will increase your capacity to 18 slots.
Bank Upgrade

With your stash upgraded, it’s time for the next step, which is to take care of your bank. With every extraction that you perform successfully, you will gain some money, and if you have enough room in your bank, you will be able to save it up for future use. This money that you earn will be useful when creating items and purchasing gear as well as prestige operators.
MIA Recovery Discount

MIA Recovery Discount is yet another useful upgrade that would be well worth buying early on. It can become rather disappointing to lose an upgraded operator when recovering him takes a large sum of money. When you always play with the same operator and have put considerable effort into improving his stats, this particular upgrade would definitely be helpful.
Gunsmith Upgrade

Upgrading Gunsmith is helpful when you acquire a great gun, but you have to make some changes to its attachments. You may acquire a gun with a decent scope and magazine, but with no suppressor or any other attachment. Without this upgrade, making even a few changes to your weapon can cost around $10,000 to $15,000. Upgrading the Gunsmith reduces the cost of weapon modifications, allowing you to customize your guns without wasting too much money.
Weapon Stash Upgrade

Weapon Storage is an upgrade that enables you to carry more weapons that will be used in later matches. You are likely to get many weapons when you loot, but not all of them are worth carrying around in your storage. Weapons that you do not want to keep can be sold instead of storing those guns that you will not use. Once you’ve upgraded the more important systems and have extra resources available, you can invest in additional weapon storage.
Vendor Upgrade

Weapons may be sold by vendors along with good accessories and equipment that will help in your mission. These may cost a lot at times, but will save you time when trying to look out for certain loot. It will become easier for you to get your equipment through upgrading vendors.
Epic Ingredient Printing

Once your stash, bank, MIA recovery, and Gunsmith have been upgraded, you need to move towards unlocking Epic Ingredient Printing. This particular upgrade is extremely significant as far as the progression in MW4 DMZ is concerned. The thing is, many better items will require high-quality materials for their crafting, and obtaining those ingredients might become quite difficult.
You need to start gathering those materials each time you come across them. Besides, it is highly recommended to unlock the recipes needed for ingredient printing as soon as possible. This way, you will be able to craft your own ingredients rather than trying to get them as loot.
