If you’re starting to explore deeper zones in Subnautica 2, you’ll eventually need a Plasteel Ingot. This advanced crafting material is one of the game’s first major progression gates, since it’s required for oxygen upgrades, vehicles, and several important mid-game recipes.
Whether you’re trying to build better survival equipment or prepare for longer dives into dangerous biomes, Plasteel Ingots quickly become one of the most important resources in the game.
The problem is that the game doesn’t clearly explain where to get Lithium early or how to unlock the Processor needed to craft the ingot in the first place. A lot of players end up wandering into high-risk areas without enough oxygen, mobility tools, or supplies, which can make early Lithium farming surprisingly frustrating.
Thankfully, once you know where to look, getting Plasteel Ingots becomes much easier.
Here’s exactly how to get Plasteel Ingots in Subnautica 2, where to find Lithium, the best early farming routes, how to unlock the Processor blueprint, and what you should craft first to make surviving deeper exploration far easier.

How to Get Plasteel Ingot in Subnautica 2
To craft a Plasteel Ingot in Subnautica 2, you’ll need access to the Processor crafting station. This is one of the first advanced crafting systems you unlock in the game, and it’s required for creating stronger materials used in mid-game progression.
Plasteel Ingot Recipe
| Material | Amount |
|---|---|
| Titanium | x2 |
| Lithium | x1 |
You cannot craft Plasteel Ingots inside the normal Fabricator. The recipe only becomes available after building a Processor in your base.
Once the Processor is unlocked, you’ll be able to combine Titanium and Lithium into a much stronger advanced material used for oxygen upgrades, vehicle components, and other important crafting recipes.
Titanium is relatively easy to collect from Metal Salvage and resource nodes, but Lithium is usually the harder ingredient early in the game.
Most players first encounter Lithium while exploring dangerous deeper biomes, so it’s a good idea to prepare extra oxygen and mobility tools before starting a farming run.
Quick Answer: How to Craft Plasteel Ingot Fast
If you just want the fastest way to get a Plasteel Ingot in Subnautica 2, the process is actually pretty simple once you know where to go. Your main goal early on is unlocking the Processor and finding a reliable Lithium source.
Fastest Plasteel Ingot Route
- Scan the Processor blueprint at the Old Habitat
- Build the Processor inside your base
- Farm Titanium from Metal Salvage and resource nodes
- Find Lithium inside The Great Jaw biome
- Combine:
- 2 Titanium
- 1 Lithium
That crafts one Plasteel Ingot.
The hardest part of this process is usually getting Lithium safely. The Great Jaw can be dangerous if you enter too early, especially with low oxygen capacity or limited mobility tools. Bringing extra Air Bladders, fins, and healing supplies can make the trip much safer and help you farm enough Lithium for multiple Plasteel Ingots in a single run.
Processor Blueprint Location
Before you can craft advanced materials like Plasteel Ingots in Subnautica 2, you’ll first need to unlock the Processor blueprint location. This crafting station is essential for mid-game progression and allows you to create several upgraded materials that aren’t available through the standard Fabricator.
Most players find their first Processor fragments inside the Old Habitat, which is located north of the starting Lifepod area. The ruins can be a little dangerous early on, so make sure to bring enough oxygen and supplies before exploring.
How to Unlock the Processor
- Travel north from the Lifepod
- Explore the Old Habitat ruins
- Scan Processor fragments
- Return to your base
- Build the Processor using the Habitat Builder
Once unlocked, the Processor quickly becomes one of the most important crafting stations in the game. It’s used for creating advanced materials like Titanium Ingots, Strong Acid, Mangalloy Ingots, and Plasteel Ingots, all of which are needed for better equipment, vehicles, and deeper biome exploration later in the game.
What the Processor Is Used For
The Processor is one of the most important crafting stations in Subnautica 2 because it lets you craft advanced materials that the normal Fabricator cannot produce. Once you unlock it, a huge portion of the game’s mid-game progression opens up, including better equipment, stronger vehicles, and upgraded survival tools.
The Processor can craft advanced resources including:
- Titanium Ingots
- Gold Ingots
- Silver Ingots
- Strong Acid
- Mangalloy Ingots
- Plasteel Ingots
Many of these materials are required for vehicle components, oxygen upgrades, crafting stations, and deeper biome exploration. For example, Plasteel Ingots are used for advanced tanks and vehicle parts, while Strong Acid and Mangalloy become important later for higher-tier crafting recipes.
Because so many important upgrades depend on processed materials, most players try to unlock the Processor as early as possible. Building one early can significantly speed up progression and make resource farming much more efficient throughout the game.
Where to Find Lithium in Subnautica 2
Lithium is easily one of the hardest materials to find early in Subnautica 2, especially when you first start crafting advanced resources like Plasteel Ingots. While Titanium is fairly common, Lithium is locked behind much more dangerous exploration zones, which is why many players struggle to progress during the early-to-mid game.
If you’re searching for a reliable Subnautica 2 Lithium location, the best early farming area is currently The Great Jaw biome.
Best Early Lithium Location
Inside The Great Jaw, Lithium can be found inside large organic resource nodes that resemble fleshy “tonsils.” These deposits are hidden throughout the biome and usually require quick movement because the area becomes dangerous fast once disturbed.
How to Collect Lithium
To safely farm Lithium:
- Equip the Sonic Resonator
- Break the organic resource node
- Quickly collect the dropped Lithium
- Escape the area before the biome becomes too dangerous
This area can be extremely hostile for underprepared players, especially if your oxygen capacity is still low or you don’t have enough mobility tools. Bringing Air Bladders, fins, healing items, and extra food can make Lithium farming much safer and help you avoid losing resources during early runs.
Recommended Gear Before Farming Lithium
Before attempting a Lithium farming run in Subnautica 2, it’s a good idea to prepare properly. The Great Jaw biome can become dangerous very quickly, and many players end up losing resources simply because they enter the area without enough oxygen, healing supplies, or mobility tools.
To make Lithium farming safer and more efficient, try bringing the following gear:
- Sonic Resonator
- Air Bladders
- Basic Fins
- Wakemaker mobility tool
- Extra food and water
- Spare medkits
The Sonic Resonator is essential for breaking the organic Lithium nodes, while Air Bladders and fins help you escape dangerous situations much faster. The Wakemaker mobility tool is also incredibly useful for navigating tight spaces and quickly retreating if the biome becomes hostile.
A lot of players underestimate how fast oxygen drains during deeper exploration, especially while searching for Lithium deposits. If possible, crafting a High Capacity Air Tank before extended farming runs can make the entire process far safer and reduce the risk of losing valuable materials.
Best Mid-Game Lithium Farming Route
Once you unlock stronger gear in Subnautica 2, farming Lithium becomes much easier and far less risky than the early-game runs through The Great Jaw. By this stage, you’ll usually have better oxygen capacity, improved mobility tools, and stronger survival equipment, which makes exploring deeper biomes much more manageable.
Most players eventually move their Lithium farming routes to:
- volcanic vent cave systems
- deeper thermal zones
- cave networks below the Tadpole Pens
These locations typically contain larger Lithium deposits and provide safer long-term farming opportunities compared to The Great Jaw. Thermal areas especially tend to have multiple resource nodes clustered together, allowing you to collect large amounts of Lithium in a single trip.
By the mid-game, it’s also worth setting up small outposts or storage lockers near major farming zones. Doing this can save a huge amount of travel time and makes it easier to stockpile Lithium for Plasteel Ingots, advanced vehicle upgrades, and other important crafting recipes later in the game.
Best Use for Your First Plasteel Ingot
Most experienced players in Subnautica 2 recommend using your very first Plasteel Ingot on the High Capacity Air Tank instead of rushing straight into vehicle crafting. While building new vehicles can be tempting, the extra oxygen from the upgraded tank provides a much bigger survival advantage during the early game.
High Capacity Air Tank Recipe
| Materials |
|---|
| Standard Air Tank x1 |
| Plasteel Ingot x1 |
This upgrade massively increases underwater exploration time and makes dangerous biome runs far safer. Having more oxygen gives you extra time to search caves, scan blueprints, gather resources, and escape hostile areas without constantly rushing back to the surface.
Honestly, it’s one of the biggest quality-of-life upgrades in the entire early game and makes almost every activity easier afterward.

Is Plasteel Ingot Worth Farming Early?
Yes — absolutely.
Plasteel Ingots are one of the most important advanced materials in the game because they unlock major progression systems, including:
- deeper exploration
- better oxygen upgrades
- advanced vehicles
- mid-game crafting progression
- safer biome exploration
Without Plasteel Ingots, progression slows down significantly once you leave the safer starting regions and begin entering more dangerous zones.
Best Early-Game Strategy for Plasteel Ingots
If you want the smoothest progression route, focusing on Plasteel Ingots early is one of the smartest decisions you can make.
Recommended Progression Order
- Unlock the Processor
- Farm Titanium from Metal Salvage
- Get the Sonic Resonator
- Collect Lithium from The Great Jaw
- Craft your first Plasteel Ingot
- Build the High Capacity Air Tank
- Start preparing for deeper biomes
Following this route makes the early-to-mid game transition much easier and helps prevent many of the survival problems players run into when exploring dangerous areas too early.
Common Mistakes Players Make
Entering The Great Jaw Too Early
One of the biggest mistakes new players make in Subnautica 2 is rushing into The Great Jaw before they’re properly prepared. Since Lithium is required for crafting Plasteel Ingots, many players head there as soon as they discover the biome, only to run out of oxygen or get trapped during exploration.
The area becomes much more dangerous if you don’t have enough mobility or survival gear, especially during longer farming runs.
Before attempting Lithium farming, make sure to bring:
- extra oxygen
- healing items
- escape tools
Having Air Bladders, upgraded tanks, fins, or mobility equipment can make a huge difference when trying to escape quickly. It’s also smart to carry spare food and water since deeper exploration can take longer than expected.
Preparing properly before entering The Great Jaw will save resources, reduce unnecessary deaths, and make early Lithium farming far less frustrating overall.
Using the First Plasteel Ingot on Vehicles
Vehicle crafting can be extremely tempting in Subnautica 2, especially once you unlock new blueprints and start preparing for deeper exploration. However, most experienced players recommend avoiding vehicle upgrades with your very first Plasteel Ingot.
Instead, the High Capacity Air Tank usually provides far better progression value early in the game.
More oxygen means:
- safer dives
- longer farming routes
- easier blueprint hunting
- fewer deaths
The extra oxygen capacity helps with almost every activity in Subnautica 2, from exploring dangerous caves to gathering rare materials like Lithium and scanning important fragments. Even simple resource runs become much less stressful once you’re no longer constantly racing back to the surface.
Vehicles are still important later on, but prioritizing oxygen upgrades first generally makes the early-to-mid game progression smoother, safer, and much more efficient overall.

Final Tips for Farming Plasteel Ingots Faster
If you want to speed up Plasteel Ingot farming in Subnautica 2, a few small preparation steps can make a massive difference. Since Plasteel Ingots are tied to important upgrades and mid-game progression, building an efficient farming routine early will save a lot of time later.
Here are some of the best tips for farming Plasteel Ingots faster:
- Scan the Processor blueprint as early as possible
- Prioritize oxygen upgrades first
- Keep storage near dangerous biomes
- Bring multiple Air Bladders during Lithium runs
- Farm extra Lithium whenever possible
- Avoid deep exploration without mobility tools
A lot of players only collect enough Lithium for a single recipe, then have to repeat dangerous farming runs again later. Stockpiling extra Lithium whenever you visit farming areas can make future upgrades much easier and reduce unnecessary trips into hostile biomes.
Once you establish a reliable Lithium farming route, Plasteel Ingots become far easier to produce and unlock a huge portion of Subnautica 2’s progression system, including advanced survival upgrades, vehicle crafting, and deeper biome exploration.
