Once you get there, you can go to the UC Distribution Center and meet with the vendor. She may have the Substrate Molecule Sieve listed, among other items.
How to craft Substrate Molecule Sieve
You can also craft this component using the Industrial Workbench or the Multiplex Fabricator. You can head directly to an industrial workbench on your Outpost or ship to start crafting. Then, you will need the following materials to craft the Substrate Molecule Sieve successfully in Starfield.
| Resource Name | Item Id | Quantity | Credits |
| Memory Substate | 5060 | 3 | 61 |
| Biosuppressant | 6542 | 2 | 15 |
| Molecular Sieve | 6557 | 1 | 86 |
| Sterile Nanotubes | 6729 | 2 | 123 |
Moreover, you can also use the Multiplex Fabricator at your Outpost to craft the Substrate Molecule Sieve. The items and the quantity required will be the same as above.
Console Command to get the Substrate Molecule Sieve
If you are tired of visiting different vendors and cannot craft the Substrate Molecule Sieve, you can use the command line to add it to your inventory.
You must add the following command to your command console.
player.additem 202782 1
This way, you can add one Substrate Molecule Sieve to your inventory. The 202782 is the Substrate Molecule Sieve item ID, and 1 at the end shows the quantity. You can increase the number at the end of this command cheat to add more Substrate Molecule Sieves.
Substrate Molecule Sieve Uses
Now that you have the Substrate Molecule Sieve, you can use it for various purposes in Starfield. This unique resource’s first and foremost use can be exploited using a Special Project (Tier 4).
You will also need to ensure that your science skills are ranked up to craft this special project. Similarly, you can use it for other Research Projects, such as Domestication 2, which is useful for your Outpost Development in Starfield.
Apart from that, you can also craft the different Outpost Modules using the Substrate Molecule Sieve, and these will include the following Industrial examples:
