How Crafting and the 3D Printer Work in MW4 DMZ
Crafting in DMZ runs through a single machine: an upgradable 3D Printer at your FOB. The official Call of Duty Deep Dive, published June 6, 2026, describes it as the center of the between-mission prep loop -- you feed in resources recovered from the field and it manufactures equipment and rarer gear, with each upgrade unlocking "increasingly advanced crafting options."
Per Deep Dive Part 1 (pre-release, October 5, 2026), the Printer is not open from your first deployment: it is one of the FOB stations you unlock as your runs in Hajin succeed. Part 1 says it draws on two inputs, Printer Resources and 3D Printer Ingredients, and that it doubles as the tool for upgrading other FOB stations.
Two conveniences are called out. Materials disassemble automatically during a run, so you are not managing salvage mid-mission, and the blog describes the inventory side as "easy to navigate." What it does not detail is the upgrade path itself -- how many tiers exist, what each costs, or which outputs unlock when.
The Deep Dive lists ten printable categories. Here is how they break down by role.
Survivability -- what you wear and carry
Plate Carriers cover different types of armor vest, and Backpacks come in varying sizes and specializations. Consumables round out staying power, spanning everything from pain killers to radiation blockers.
Offense -- what you throw and deploy
Lethals are offensive equipment built to damage or eliminate threats, with Tacticals as their non-lethal strategic counterpart. Above both sit Fire Support Items -- deployable offensive killstreak support for when a fight escalates past what you are carrying.
Utility and abilities
The Gear category covers tactical equipment like NVGs and Parachutes. Field Upgrades are the standout here, and the blog draws its one explicit DMZ-vs-Multiplayer line on them: unlike in Multiplayer, Field Upgrades in DMZ do not recharge. That single sentence is the clearest mechanical distinction the Deep Dive makes for the whole system -- an ability you print is an ability you spend, not one that cycles back.
The two structural outliers
Two categories are not really "products." Tracked Recipes is a set of tagged recipes you are actively hunting -- a pursuit rather than a finished item. The two blogs each cover part of where recipes come from: the June post ties learning and finding recipes to looting in Hajin, and Part 1 (pre-release) says the DMZ Progression track hands out key Printer Recipes. How a recipe becomes "tracked" is still not explained. Special Items is the catch-all, described only as "a wide variety of items used for a wide variety of purposes."
Rarity is tied to how far you push
The Deep Dive links crafting depth directly to map progression, and the language is blunt: "the deeper players push into the region, the more opportunities they uncover to secure rarer resources needed to support stronger loadouts and specialized playstyles." In practice that ties the FOB crafting loop back to in-mission risk -- the best Printer outputs depend on resources found deeper in, not on what is lying around near your infil.
Still unconfirmed
The Printer's upgrade tiers, per-tier resource costs, and which categories gate behind which tier are all absent from the Deep Dive. So is how a recipe gets onto the tracked list.
