Efficiency Matrix: What It Does & Savings Calculator

Last Updated: October 26, 2026

Efficiency Matrix is a production enhancer for the Fabricator. It reduces electricity, water, fuel and gas used per craft by 10%. Each module has 20 charges; each craft uses 1. It does not boost power generation.

Where it goes: on one of the two small plates low down on the Fabricator (or Food Processor), not on the ship. Recipe: 1 Alloy Frame + 1 Conduit Wiring, built at the Fabricator for 5 Wh, Tier 8.

Effects and charges checked in November 2025; recipe and unlock level checked against the Update 6 item data (game 0.10.0) on October 26, 2026.

Efficiency Matrix Savings Calculator

Enter the unmodified cost of one item from your game. Assumes one module at a time, replacing it when depleted.

Number of craftselectricity per craft (Wh)water per craft (L)fuel per craft (L)gas per craft (L)

Matrices needed: 0
Charges left in the last matrix: 0
electricity saved: 0 Wh
water saved: 0 L
fuel saved: 0 L
gas saved: 0 L

Zero crafts needs no matrix. A fully used last matrix has no charges left. These are gross resource savings, not net savings or payback.

Compare with Other Production Enhancers

The same crafts with each module fitted instead. Each saving is the module's listed percentage of the per-craft cost you entered. Every effect matches on the in-game tooltip or skill card and the wiki. Efficiency Matrix figures predate Update 5.5. Module counts are only shown for Efficiency Matrix.

Resources saved by each production enhancer for the crafts entered above
Module	water saved	fuel saved	gas saved	Crafting speed	Modules needed
Efficiency Matrix	0 L	0 L	0 L	No change listed	0
Voltage Minimizer	No change listed	No change listed	No change listed	−40% (slower)	—
Resource Optimizer	0 L	0 L	0 L	−30% (slower)	—

Each row assumes that one module alone is fitted. Voltage Minimizer cuts electricity the most, Resource Optimizer cuts all four resources by more than Efficiency Matrix, and both make crafting slower. Only Efficiency Matrix has a verified charge count.

Where to Put the Efficiency Matrix

Move the module near the metal mounting plates below the Fabricator to snap it into place. The plates are small metal panels with a 2×4 grid of holes, low down on the Fabricator or Food Processor itself. Hold the module against one and it snaps on; it does not go anywhere else on the ship.

Two modules can be fitted at once, one on each plate: the Fabricator has 2 mounting plates. The calculator counts the saving of one module at a time.

Efficiency Matrix also fits the Food Processor.

Remove the module once its charges run out. Plan replacements from the number of items you want to craft.

Recipe and Unlock

Efficiency Matrix requires Tier 8. Recipe: 1 Alloy Frame + 1 Conduit Wiring, built at the Fabricator for 5 Wh.

Checked against Early Access 0.8.5 (Update 5.5) and the Update 6 item listing (game 0.10.0) on 2026-10-26.

Is the Efficiency Matrix Worth It?

One module covers 20 crafts and saves 10% on each, so over its life it saves the electricity, water, fuel and gas of about 2 crafts. It costs 1 Alloy Frame + 1 Conduit Wiring, built at the Fabricator for 5 Wh. That pays off on crafts that use a lot of power, water or fuel, or where those are scarce; for cheap crafts it hardly matters. Unlike the other three listed below, it lists no crafting slowdown.

Short of electricity
Voltage Minimizer
−80% electricity
crafting 40% slower
Short of water, fuel or gas
Conservation Coil
−60% fuel, gas and water, −10% electricity
crafting 50% slower
Short of a bit of everything
Resource Optimizer
−50% electricity, −30% water, fuel and gas

Short of time
Efficiency Matrix
−10% electricity, water, fuel and gas
no slowdown listed; 20 crafts per module

Other Production Enhancers

These modules serve different crafting needs. Effects that match on the in-game skill card and the wiki feed the comparison table in the calculator above. Charge counts and recipes vary between readings, so we do not count how many of these modules you need or rank a best enhancer.

Voltage Minimizer (Voltage Minimiser)

Voltage Minimizer substantially reduces crafting electricity use and can be fitted to a Fabricator. It can also reduce the energy needed to make batteries.

Limits of These Observations

These are single observations, not a success rate or a complete module count.

One doubling module never doubled its output before being used up, while another doubled 3 of 4 crafts. This is a small sample, not a measured success rate.

Efficiency Matrix FAQ

What does Efficiency Matrix do?

It is a production enhancer for crafting. Each craft uses 10% less electricity, water, fuel and gas. It does not increase generator output. This evidence predates Update 5.5 and has not been re-verified against it.

How long does one Efficiency Matrix last?

One module has 20 charges and uses 1 charge per crafted item. Remove the module when its charges run out.

Where do I put the Efficiency Matrix?

On the Fabricator, not the ship. Move the module near the metal mounting plates below the Fabricator to snap it into place. The plates are small metal panels with a 2×4 grid of holes, low down on the Fabricator or Food Processor itself. Hold the module against one and it snaps on; it does not go anywhere else on the ship. Efficiency Matrix also fits the Food Processor.

Do two Efficiency Matrices stack?

Two modules can be fitted at once, one on each plate: the Fabricator has 2 mounting plates. The calculator counts the saving of one module at a time.

What is the Efficiency Matrix recipe?

1 Alloy Frame + 1 Conduit Wiring, built at the Fabricator for 5 Wh. It unlocks at Tier 8 in the Skills menu.

Is the Efficiency Matrix worth it?

How is Efficiency Matrix different from Voltage Minimizer and Resource Optimizer?

Efficiency Matrix lowers electricity, water, fuel and gas use by 10% and has 20 charges. Voltage Minimizer: electricity consumption −80%, crafting speed −40%. Resource Optimizer: electricity consumption −50%, water consumption −30%, fuel consumption −30%, gas consumption −30%, crafting speed −30%. Both of those make crafting slower. Their effects are confirmed, so the calculator compares what each module saves on the same crafts. Their charge counts are not, so it counts modules needed for Efficiency Matrix only.
