UU-Matter

UU-Matter is the IC2 end-game item crafted from raw EU energy in a Mass Fabricator and used to make diamonds, iridium and more.

Description

UU-Matter (IndustrialCraft 2 mod) is the end-game resource of the IC2 tech tree, used to craft virtually any vanilla or modded item through dedicated recipes. UU-Matter is produced exclusively by the Mass Fabricator machine, which converts EU energy directly into raw matter at a base cost of 1,000,000 EU per single UU-Matter unit. Mass Fabricator output is dramatically accelerated by Scrap and Scrap Boxes fed from the Recycler, multiplying production by roughly 6x and reducing the effective energy cost. The Mass Fabricator demands a steady high-voltage supply, so most setups pair it with Nuclear Reactors, Solar Flower arrays, or large MFSU banks. UU-Matter recipes cover diamonds, iron ingots, redstone, lapis lazuli, glowstone dust, snowballs, and crucially iridium ore, the precursor of the Quantum-Suit armor set. UU-Matter is a Java Edition IC2 item with no Bedrock equivalent and exists only as an inventory item, never as a placeable world block. UU-Matter sits at the IC2 progression cap, marking the moment a player transitions from grinding ores to producing them on demand.

Guide

How to produce UU-Matter with a Mass Fabricator in IC2

  1. 1

    Build a Mass Fabricator

    Craft a Mass Fabricator from advanced machine casings, advanced circuits, glowstone dust and a Lapotron Crystal at a standard crafting table.

  2. 2

    Wire high-voltage EU input

    Connect the Mass Fabricator to an HV supply such as an IC2 Nuclear Reactor or an MFSU through HV transformers and glass fibre cable.

  3. 3

    Feed Scrap from a Recycler

    Run a Recycler on cobblestone or dirt to make Scrap, then auto-pipe Scrap or Scrap Boxes into the Mass Fabricator to cut the 1,000,000 EU per UU-Matter cost by about 6x.

  4. 4

    Collect UU-Matter units

    Wait for the progress bar to fill: IC2 Classic drops one UU-Matter item into the output slot, while current IC2 Experimental stores liquid UU-Matter drained with a Universal Fluid Cell.

  5. 5

    Craft target resources

    Turn UU-Matter into diamonds, iron, redstone, glowstone, snowballs or iridium ore — in current IC2 Experimental with a Replicator loaded with scanned patterns, in IC2 Classic with crafting patterns on a standard crafting table.

Tip

Iridium ore is the most valuable UU-Matter product: Iridium Plates pressed from it are required for every Quantum-Suit piece. Rare iridium shards found while exploring or in End Cities can be compressed into ore, but UU replication is the scalable route.

Frequently asked questions

How is UU-Matter produced?

UU-Matter is produced only by the IC2 Mass Fabricator, which converts EU energy into matter at a base cost of 1,000,000 EU per unit.

Does Scrap really speed up the Mass Fabricator?

Yes. Feeding Scrap or Scrap Boxes from a Recycler multiplies output by about 6x, dropping the effective EU cost per UU-Matter to roughly 166,000 EU.

What can you craft from UU-Matter?

UU-Matter recipes include diamonds, iron ingots, redstone, lapis lazuli, glowstone dust, snowballs and iridium ore — the last being mandatory for the Quantum-Suit armor.

Can UU-Matter be placed as a block?

No. UU-Matter exists only as an inventory item in IC2; it cannot be placed in the world like a regular Minecraft block.

Is UU-Matter available on Bedrock Edition?

No. IC2 and UU-Matter are Java Edition only and do not exist in Bedrock Edition Minecraft.
